    Appeal from the Iowa District Court for Scott County, Mark J.
    Smith, Judge.
    A personal injury plaintiff seeks further review of court of appeals
    decision ordering a new trial on her premises liability claims. DECISION
    OF COURT OF APPEALS VACATED; DISTRICT COURT JUDGMENT
    REVERSED AND CASE REMANDED FOR NEW TRIAL.
    Mark McCormick of Belin McCormick, P.C., Des Moines, for
    appellants.

    WATERMAN, Justice.
    We must decide whether a new trial is required in this premises
    liability action.   Brenda Alcala, a business guest at the Courtyard by
    Marriott1 in Bettendorf, slipped and fell on its icy sidewalk, breaking her
    ankle. The jury found Marriott ninety-eight percent at fault and Alcala
    two percent at fault and awarded her damages of $1.2 million. The court
    of appeals concluded the district court’s jury instructions were erroneous
    and ordered a new trial.      The court of appeals held the district court
    abused its discretion by denying Marriott’s requested jury instruction on
    the continuing-storm doctrine, erred by submitting a negligent-training
    theory without substantial evidence, and erroneously instructed the jury
    on private industry safety codes.           One judge dissented in part,
    concluding the district court correctly declined to instruct on the
    continuing-storm doctrine based on the lack of evidence of the requisite
    storm. The dissent invited our court to clarify whether our standard of
    review for rulings declining requested instructions is for abuse of
    discretion or correction of errors at law. We granted Alcala’s application
    for further review.
    For the reasons explained below, we conclude a new trial is
    required.   We hold that our standard of review for rulings denying a
    requested jury instruction is for correction of errors at law. We conclude
    the district court erred by submitting a negligent-training theory without
    evidence of the standard of care for training employees on deicing or
    breach of that standard. Because the jury returned a general verdict, a
    new trial is required. A new trial is also required because the district
    1Appellants     are Marriott International, Inc. and Courtyard Management
    Corporation, doing business as Quad Cities Courtyard by Marriott. We refer to the
    appellants collectively as Marriott.

    court, over conflicting expert testimony, erroneously instructed the jury
    that an icy walkway violated a private safety code governing slip-resistant
    construction materials.   We decline to decide the applicability of the
    continuing-storm doctrine.    On remand, the parties and district court
    may address whether the doctrine should be abandoned in light of our
    adoption of section 7 of the Restatement (Third) of Torts, Liability for
    Emotional and Physical Harm.      We vacate the opinion of the court of
    appeals, reverse the district court judgment, and remand the case for a
    new trial consistent with this opinion.
    I. Background Facts and Proceedings.
    Alcala, a software consultant, often traveled away from her Texas
    office and visited clients that were implementing new software. Alcala
    made these in-person visits so that she could assist clients with final
    tests and troubleshooting.     On January 18, 2010, Alcala arrived in
    Bettendorf on one such business trip, intending to spend an entire
    workweek with the client before returning to Texas. She checked into the
    Courtyard by Marriott in Bettendorf, a few blocks from the office where
    Alcala would be working.     Just before 8 a.m. on January 21, Alcala
    slipped and fell while exiting the hotel en route to her client’s office,
    breaking her ankle.
    In January 2012, Alcala filed suit against the defendants, alleging
    Marriott negligently caused her injuries because it allowed ice to
    accumulate on its outdoor walkways, failed to maintain safe premises,
    failed to properly train their employees responsible for addressing icy
    sidewalks, and failed to warn guests of the dangerous condition.       The
    case proceeded to trial in February 2014.
    A. The Weather. An official weather recap encompassing a broad
    thirteen-county portion of eastern and southeastern Iowa described “an
    4
    ice storm over much of eastern Iowa . . . with widespread ice
    accumulations of ¼ to ½ inch” that occurred on January 20. The recap
    did not mention anything about conditions in that thirteen-county area
    on January 21, the day Alcala fell.
    Witnesses at trial testified about the weather on the morning of
    January 21. The Marriott restaurant employee who attended to Alcala
    immediately after her fall testified “it was bad that morning” but stated
    she had no difficulty entering the building when she arrived for her shift
    at 5:15 a.m. and it was not raining or misting at the time Alcala fell
    nearly three hours later. The employee staffing the front desk recalled no
    mist at the time Alcala fell.   The hotel manager on duty at the time
    stated, “It was very gray, and I know there was a lot of moisture.” One of
    the paramedics who responded to the 911 call acknowledged “it was
    rough conditions out.” The other paramedic confirmed “there was some
    bad weather,” “it was quite icy,” and “[t]here had been an ice storm” but
    could not remember precise details. The on-call physician who treated
    Alcala at the hospital after her fall explained that on his morning
    commute, sidewalks and roads were slick and icy and “there were
    accidents all over town.”    Alcala’s contact with her Bettendorf client
    testified “the weather conditions were not good” and affirmed “everyone
    in the Quad Cities was dealing with the effects of th[e] storm that
    morning.”
    When asked if she recalled the weather on January 21, Alcala’s
    client contact testified, “We had some freezing rain” without quantifying
    the precipitation or specifying when it occurred in relation to Alcala’s
    injury.   A paramedic testified generally that “[t]here was a storm that
    morning.” A restaurant employee testified, “[W]e had just had, like, one
    of those freak ice storm things.”         However, she further testified she
    5
    “believe[d]” the freak ice storm went “into the morning hours as well.”
    She acknowledged that “the weather may have been kind of waxing and
    waning that morning, as it often does during storms.” Marriott witness
    Margaret DePaepe, the maintenance employee responsible for exterior
    walkways during the overnight shift, testified that whatever precipitation
    occurred “was slowing down” when her shift ended around 6 a.m. on
    January 21 and that any precipitation “had pretty much stopped” by
    5:40 a.m.
    Certified weather records from the National Climatic Data Center
    show mist and freezing rain at the Quad City International Airport in
    nearby Moline, Illinois—about eight miles south of the Marriott—
    beginning on the morning of January 20. The records show freezing rain
    last fell at the airport around 6 p.m. that day, while mist was virtually
    continuous throughout the day and into the night. About half an inch of
    precipitation accumulated that day, with only trace amounts accruing
    after 3 p.m. and the last trace accumulating no later than 7 p.m. Mist
    continued overnight and into the morning of January 21, ending around
    noon.     However, there were no new accumulations, even in trace
    amounts. Ambient temperatures fluctuated slightly, reaching thirty-four
    degrees Fahrenheit by 2:15 a.m. on January 21 but decreasing to thirty-
    two degrees by 7:52 a.m. Overall data shows 0.53 inches of precipitation
    accumulating on January 20, with no accumulation after 7 p.m. on that
    day or at any point on January 21.2
    Data from the Davenport Municipal Airport, about eight miles
    northwest of the Marriott, provides less detail. Unlike the Moline data,
    2The records list total precipitation as “0.00” for January 21. In context, this
    does not include even trace amounts because other dates in January show total
    precipitation as “T,” standing for “trace.”
    6
    the Davenport data does not display a log of observations by hour.
    Rather, it is a daily summary.     On January 20, the Davenport data
    reflects 0.32 inches of precipitation with “fog or mist” and “freezing rain
    or drizzle.” On January 21, it reflects trace amounts of precipitation, the
    same two conditions and an additional condition of “smoke or haze”—but
    because the data is a twenty-four-hour summary, it contains no specific
    timeline for these observations.
    B. Training of Marriott Employees.        No witness testified as to
    the standard of practice for training employees on deicing walkways or
    what employees should be taught on that subject.         DePaepe testified
    about her protocol for clearing ice and snow during a shift:
    Q. Why don’t you tell the jury what your procedures
    are for shoveling and salting throughout your shift. A. We
    just go outside and take a bucket of salt, and then we—take,
    at the time, a water thing.
    Q. Like a pitcher, a scooper? A. It was a water
    pitcher. And we just sprinkled it everywhere that we could
    possibly find the ice.
    Q. Okay. Now, if there’s snow or if there’s ice, as it’s
    falling, do you just do the sprinkling, or do you shovel as
    well? A. We shovel as best we could.
    Q. And when you do shovel, do you do that before or
    after the saltings? A. Before, and then we put the salt
    down.
    Q. So you try to get as much stuff out of the way and
    then you sprinkle salt on it? A. Yes.
    ....
    Q. When you’re out there salting throughout the
    night, are you checking your own work? Are you walking
    over the areas that you’re salting? A. We check our own
    work.
    Q. Okay. So you’re sprinkling and you’re walking
    behind it; is that right? A. Yes.
    Q. Now, what if you’re walking, walking as you’re
    sprinkling, walking back to put your salt and materials back
    in the shed, what if you notice a slick spot? A. Then we put
    more . . . salt and we take care of that spot as soon as
    possible.
    7
    ....
    Q. So you have a standard operating procedure of
    going out at least three times in your shift and walking the
    premises and inspecting and shoveling and salting if
    necessary. A. Yes.
    DePaepe added that no supervisor ever told her to limit the quantities of
    deicer used on exterior walkways.
    On cross-examination, DePaepe elaborated on the extent of her
    training on snow and ice removal techniques:
    Q. When you were trained by Marriott, did you have
    an understanding that if people did not properly attend to
    the outside sidewalk, if there was, say, an ice storm and the
    sidewalk became slippery, that it could become dangerous
    for people to walk on it? A. Yes.
    Q. You were trained about that? A. Yes.
    Q. That was important to you? A. Yes.
    ....
    Q. How long were you taught that either salt or de-
    icing compound could be on that sidewalk before it would
    become inert and not effective? Were you ever taught that?
    A. Hum-um.
    Q. Is that a no? A. No.
    Q. All right. Were you ever taught that you have to be
    concerned that simply spreading salt would simply melt the
    ice and it might refreeze? A. Yes.
    Q. And if it refroze, you would have to actually use a
    shovel, true? A. Yes.
    Alcala’s counsel asked DePaepe to comment on a copy of Marriott’s
    training materials:
    Q. Do you recognize this [document entitled] outdoor
    safety measures? A. No.
    Q. This was produced by a Marriott lawyer, saying
    that these are the type of training that you received. You
    don’t remember seeing this? A. It’s been a while. I haven’t
    seen these for a while . . . .
    Q. Fair enough. It may not be fair. But would you
    agree that snow and ice on an exterior sidewalk can be a
    hazard? A. Yes.
    8
    Q. And would you agree that when ice forms, it would
    be important for a Marriott employee to remove it at once?
    A. Yes.
    Q. And if a Marriott employee didn’t do that, that
    would be a problem for the customers. A. Yes.
    Q. And my understanding is that when I asked you in
    your deposition if you had received any specific training
    whatsoever from Marriott as to the proper way to remove ice,
    you just said they told us to go out there and shovel and
    salt. A. Yes.
    On redirect examination, DePaepe clarified the types and frequency
    of training she received from Marriott:
    Q. What kinds of training did you guys receive at the
    Marriott? A. What we did was go through videos, and when
    it gets close to the winter season, we have a meeting with all
    of the house people, all of our maintenance people, I should
    say, and they go through the procedures of what should . . .
    be done and how it should be done.
    Marriott’s counsel offered, and the court received as an exhibit, the
    packaging from the deicer DePaepe testified she used:
    Q. Now, you can see from this bag—it says that it
    works—it has melting power down to negative 15 degrees; is
    that fair? A. Yes.
    Q. Okay. Now, on the back it has different things
    about how to use, and the storage, it cautions you not to use
    too much, tells you only to apply about a quarter cup per
    square yard. Does it say anything on here about needing to
    reapply every 15 minutes, every half-hour? A. No.
    Q. Does it say anywhere here that this won’t work
    longer than an hour and a half or two hours? A. No.
    Q. Did you have any reason to believe that it
    wouldn’t? A. No.
    Q. Had it been working appropriately when you’d been
    taking two-and-a-half to three-hour breaks in between
    throughout the night? A. Yes.
    DePaepe testified she observed no ice problem on the sidewalk at
    those intervals.    However, other witnesses contradicted her.         One
    paramedic who responded to the 911 call estimated the sidewalk in the
    location where Alcala fell was “eight or higher” on a ten-point scale of
    9
    slipperiness—where ten denotes “as slippery as it possibly could be”—
    even though DePaepe testified she had applied deicer at approximately
    5:30 a.m. that day. The paramedic further testified the fire department’s
    personnel spread their own deicer on the sidewalk to allow the
    paramedics sufficient traction to reach and rescue Alcala safely.
    Other evidence relevant to the training of Marriott’s employees
    came from the company’s operations manager for the Bettendorf
    location. The manager explained each maintenance person completes a
    checklist of tasks during each shift, and she affirmed DePaepe’s
    statement that “standard operating procedure” under the checklist
    required at least three inspections of walkways and floors during each
    eight-hour shift.   The operations manager further stated, “[I]t was
    understood with . . . anyone working those shifts, that if it needed to be
    done more often, to absolutely do it more often.” No witness testified as
    to any deficiency in Marriott’s training procedures or documents.
    C. Private Safety Standards. Alcala and Marriott each presented
    an expert addressing industry standards for slip resistance and snow
    and ice removal.    Russell Kendzior testified on Alcala’s behalf about
    standards promulgated or approved by the American Society for Testing
    and Materials (ASTM) and the American National Standards Institute
    (ANSI).    He   opined   the   standards   were   applicable   under   the
    circumstances of this case even though they are voluntary, not
    mandatory.   Section 5.13 of ASTM Standard F1637 requires walkway
    surfaces to be slip resistant under expected environmental conditions
    and use, especially when conditions may be reasonably foreseeable.
    Kendzior opined that the phrase “expected environmental conditions”
    accommodates the notion that during some weather events it may be
    impossible to provide a perfectly slip-resistant surface.   Kendzior also
    10
    discussed sections 5.7.1.1 and 5.7.1.2 of the standard, which state
    exterior walkways “shall be slip resistant” and consider a slippery surface
    substandard. Kendzior testified, “[B]room-finished sidewalks are the
    industry standard. That’s what’s required by code. . . . [T]hey provide a
    very ample degree of slip resistance when dry.” In Kendzior’s opinion,
    however, an icy surface is by definition slippery and therefore
    substandard under that code.
    ANSI standard A1264.2, to which Kendzior also referred, provides
    suggested protocols for clearing snow and ice from walkways and parking
    lots. Specifically, section 10.3.1 of the standard instructs land occupiers
    to use deicing compounds according to manufacturer instructions that
    may include reapplication after a length of time. Kendzior read from the
    ASTM and ANSI standards during his testimony while the jury viewed
    them via a projector, but neither party introduced a copy of them into
    evidence.
    In contrast, Marriott’s expert, architect Alan Bowman, testified the
    slip resistant ASTM standard applied to the finish applied to the concrete
    surface, not slipperiness from snow or ice.        He noted ASTM once
    considered promulgating a standard for snow and ice removal but
    scrapped the proposal because the organization’s members could not
    agree on an appropriate global standard. Bowman testified the Marriott’s
    sidewalk was constructed with broom-finished concrete that met the
    ASTM standard:
    Q. Now, let’s look at the cement itself. What kind of a
    finish is on this concrete? A. Well, the metric that you use
    in terms of sidewalk performance is its slip resistance, and
    the most cost effective way to achieve slip resistance with
    concrete is to broom finish it. You take a stiff bristle broom
    while the concrete is, what we call, thumbprint hard, and
    you drag the broom across the concrete and then let it finish
    curing, and that creates a fine corduroy effect. It’s about
    11
    l6th-of-an-inch-high grooves in the concrete. All of the
    measures that I’m familiar with, ASTM standards, for
    example, and the ANSI standards, consider broom-finished
    concrete to be slip resistant, and that’s on the scale of,
    basically, from zero, which would be just slick as glass, to
    one. And broom-finished concrete, wet or dry, always ranks
    between 0.5 and 0.8, so it’s considered, under wet or dry
    conditions, to be a slip-resistant surface.
    Q. And      this     was     broom-finished     concrete.
    A. Everything, according to the Donahue site plan
    documents and everything that I witnessed in a walk-around
    of the Marriott facility, everything is broom-finished concrete.
    Q. And that, I think, even Mr. Kendzior mentioned, is
    really the standard in the industry. A. Pardon me?
    Q. Mr. Kendzior mentioned that’s the standard in the
    industry, broom-finished concrete. A. Yes.
    Q. Now, just to make it clear, though, that means that
    this surface is slip resistant wet or dry? A. Wet or dry, yes.
    D. The Jury Instructions.       Before submitting the case to the
    jury, the parties made a record on jury instructions. Marriott sought a
    jury instruction detailing the continuing-storm doctrine. This doctrine
    provides that, absent unusual circumstances, a premises occupier may
    “await the end of the storm and a reasonable time thereafter to remove
    ice and snow from an outdoor entrance walk, platform, or steps.” Reuter
    v. Iowa Tr. & Sav. Bank, 
    244 Iowa 939
    , 943, 
    57 N.W.2d 225
    , 227 (1953)
    (quoting Walker v. Mem’l Hosp., 
    45 S.E.2d 898
    , 902 (Va. 1948)). Marriott
    contended it was entitled to this instruction because several witnesses
    testified generally that the weather was bad on the morning of January
    21 and because the certified weather records from nearby locations
    reflected mist that day. See Rochford v. G.K. Dev., Inc., 
    845 N.W.2d 715
    ,
    718 (Iowa Ct. App. 2014) (concluding the doctrine includes freezing rain,
    not just blizzards).   Thus, Marriott asserted the jury should decide
    whether the storm was continuing when Alcala fell or, if it had ended,
    whether Marriott waited a reasonable time after the storm passed to
    remove the ice from the sidewalk where Alcala fell.
    12
    The district court refused to give the instruction because it
    concluded there was insufficient evidence supporting it.         The district
    court concluded trace precipitation and mist do not constitute a “storm”
    within the plain meaning of the word or under our caselaw applying the
    continuing-storm doctrine. Indeed, the district court noted the weather
    records considered mist to be an obscuration like fog, not a type of
    precipitation.    Furthermore, the district court concluded witnesses’
    general testimony that roads and sidewalks were slick and icy on the
    morning of January 21, that “it was rough conditions out,” or that “the
    weather conditions were not good” spoke only to the persisting effects of
    the storm, not whether it was actively continuing at times relevant to this
    case.
    The court also overruled Marriott’s objections to two additional
    instructions. First, Marriott contended the ASTM and ANSI standards
    were not applicable and it was therefore inappropriate to instruct the
    jury it could conclude violation of the standards was evidence of
    negligence. Second, Marriott contended there was insufficient evidence
    to support improper training, one of Alcala’s asserted specifications of
    negligence. The district court concluded a jury instruction on industry
    standards was appropriate despite the experts’ conflicting opinions on
    the standards’ applicability. It also concluded DePaepe’s testimony was
    substantial evidence supporting an instruction including improper
    training as a specification of negligence.
    Instruction No. 20, as submitted to the jury, stated,
    American Safety and Testing Materials (ASTM)
    Standard Practice for Safe Walking Surfaces requires exterior
    walkways shall be maintained so as to provide safe walking
    conditions (5.7.1). In addition, said standards require that
    exterior walkways shall be slip resistant (5.7.1.1). Finally, if
    13
    an exterior walkway is slippery, it is to be considered
    substandard (5.7.1.2).
    American National Standards Institute (ANSI) require
    that where snow and ice exists in pedestrian walkways, safe
    maintenance techniques shall include plowing, shoveling,
    deicing, salting or ice melting chemicals, and sanding, as
    needed (10.3.1).
    You may consider a violation of these standards as
    evidence of negligence.
    Instruction No. 16 allocated to Alcala the burden of proving Marriott was
    negligent in at least one of four ways: (1) improper training, (2)
    inadequate maintenance, (3) failing to inspect the walkway, or (4) failing
    to provide a slip-resistant walkway.
    E. The Verdict and Appeal. The jury returned a general verdict
    finding Marriott negligent without identifying which specification or
    specifications of negligence Alcala proved. The jury allocated ninety-eight
    percent of the fault to Marriott, two percent to Alcala, and awarded
    Alcala total damages of $1.2 million for medical expenses, lost wages,
    pain and suffering, and loss of bodily function.      Marriott moved for
    judgment notwithstanding the verdict, remittitur, or new trial, asserting
    the district court erred in denying a continuing-storm instruction and in
    submitting the other instructions to which Marriott objected.          The
    district court denied the motion.
    Marriott appealed, and we transferred the case to the court of
    appeals. The court of appeals ordered a new trial because it concluded
    the evidence supported a continuing-storm instruction and did not
    support the instructions on industry standards and improper training.
    One judge dissented in part, concluding the district court correctly
    refused to instruct on the continuing-storm doctrine.         We granted
    Alcala’s application for further review.
    14
    II. Standard of Review.
    We have said “[w]e review a court’s refusal to give an instruction
    for an abuse of discretion, while we review challenges to jury instructions
    for correction of errors at law.” Anderson v. State, 
    692 N.W.2d 360
    , 363
    (Iowa 2005).    However, this distinction is relatively recent, growing
    primarily out of a 2003 decision. See State v. Piper, 
    663 N.W.2d 894
    ,
    914 (Iowa 2003), overruled on other grounds by State v. Hanes, 
    790 N.W.2d 545
    , 551 (Iowa 2010).       In Piper, we stated “review of alleged
    instructional error depends on the nature of the supposed error” and
    cited a case indicating the refusal to give an inference instruction on
    alleged spoliation is properly reviewed for an abuse of discretion.        
    Id. (citing State
    v. Langlet, 
    283 N.W.2d 330
    , 336 (Iowa 1979) (holding the
    district court did not abuse its discretion in denying a spoliation
    instruction as there was no evidence of an intent to destroy evidence)).
    We conclude Langlet correctly states the standard of review of the
    district court’s refusal to give an inference instruction on spoliation
    because that instruction acts as a discovery sanction and discovery
    sanctions are discretionary. See Hendricks v. Great Plains Supply Co.,
    
    609 N.W.2d 486
    , 491 (Iowa 2000) (discussing the spoliation inference
    and its remedies); Farley v. Ginther, 
    450 N.W.2d 853
    , 856 (Iowa 1990)
    (noting the discretionary nature of discovery sanctions).      However, the
    standard of review applied in Langlet and referenced in Piper does not
    extend to all refusals to give a requested jury instruction.
    “Iowa law requires a court to give a requested jury instruction if it
    correctly states the applicable law and is not embodied in other
    instructions.” Sonnek v. Warren,

    2000); Herbst v. State, 
    616 N.W.2d 582
    , 585 (Iowa 2000).          The verb
    15
    “require” is mandatory and leaves no room for trial court discretion.
    Thus, we clarify today that absent the discretionary component present
    in Langlet, we review refusals to give a requested jury instruction for
    correction of errors at law. See, e.g., DeBoom v. Raining Rose, Inc., 
    772 N.W.2d 1
    , 5, 11–14 (Iowa 2009) (reviewing multiple jury instruction
    claims, including refusal to give a requested pretext instruction, for
    errors at law); Koenig v. Koenig, 
    766 N.W.2d 635

    instruction for errors at law); Banks v. Beckwith,

    instruction for errors at law); Pexa v. Auto Owners Ins. Co., 
    686 N.W.2d 150
    , 160 (Iowa 2004).          To the extent our cases perpetuate the Piper
    distinction     and      extend      the     abuse-of-discretion        analysis      to
    nondiscretionary refusals to give requested jury instructions supported
    by the evidence and applicable law, we overrule them on that issue.3
    III. Analysis.
    A. Negligent Training. We must decide whether the district court
    erred by submitting the negligent-training theory without any testimony
    on the standard of care for training or its breach. It is axiomatic that
    proof of the applicable standard of care and its breach are required to

    does not disturb the substantive legal conclusions in these decisions.
    16
    recover in tort. See Thompson v. Kaczinski, 
    774 N.W.2d 829
    , 834 (Iowa
    2009) (“An actionable claim of negligence requires ‘the existence of a duty
    to conform to a standard of conduct to protect others, [and] a failure to
    conform to that standard . . . .’ ” (quoting Stotts v. Eveleth, 
    688 N.W.2d 803
    , 807 (Iowa 2004))). Dismissal is required when the record contains
    no evidence regarding the applicable standard of care or its breach. See
    Godar v. Edwards, 
    588 N.W.2d 701
    , 709–10 (Iowa 1999) (affirming
    directed verdict in defendant’s favor on claims against employer for
    negligent hiring, retention, and supervision); Hartig v. Francois, 
    562 N.W.2d 427
    , 430–31 (Iowa 1997) (holding defendant was entitled to
    directed verdict on negligence claims based on insufficient evidence of
    the standard of care or its breach); Fisher v. Dallas County, 
    369 N.W.2d 426
    , 431 (Iowa 1985) (affirming dismissal because the “record contains
    no evidence regarding that standard of care” or its breach).
    Marriott argues on appeal that reversal is required because “[t]he
    record contains no evidence of a standard of care imposing a discrete
    duty on Marriott to instruct employees about a specific period of time
    that a particular deicing compound will remain effective.” Alcala argues
    expert testimony was not required to establish the standard of care for
    training employees on ice removal.       Regardless, there must be some
    evidence or testimony to support the instruction on negligent training.
    No witness, lay or expert, testified that Marriott should have trained
    DePaepe on the durational effectiveness of the deicer.         Cf. Tomeo v.
    Thomas Whitesell Constr. Co., 
    823 A.2d 769
    , 777 (N.J. 2003) (affirming
    summary judgment dismissing negligent-training claim as to employee’s
    use of snowblower, concluding “[n]o special training was required to be
    given . . . because it is a consumer product” with adequate warnings and
    instructions). No expert or lay witness testified about any shortcoming
    17
    in Marriott’s training or what training should be provided. Alcala argues
    the jury can find Marriott breached a duty to train DePaepe by
    connecting these dots: there was ice on the sidewalk; therefore, DePaepe
    did not apply deicer properly; therefore, Marriott did not train her
    properly.   If that is sufficient, then going forward, employers could be
    sued for negligent training whenever there is an avoidable accident. We
    conclude that the evidence in this case was insufficient to support a
    negligent-training instruction or specification of negligence.
    Other courts have held that negligent-training claims fail as a
    matter of law without testimony establishing the standard of practice for
    training employees for the job at issue. Judge Merrick Garland recently
    surveyed many such decisions in Burke v. Air Serv International, Inc., 
    685 F.3d 1102
    , 1106–07 & n.2 (D.C. Cir. 2012) (affirming summary judgment
    dismissing negligent-training claim).      See also Moore v. District of
    Columbia,   
    79 F. Supp. 3d 121
    , 144–45 (D.D.C. 2015) (surveying
    authorities and granting summary judgment dismissing negligent-
    training claims).   It is not enough to show the mistakes or negligent
    conduct of the employee; rather, to recover against the employer under a
    negligent-training theory, evidence of a specific standard of care for
    training and its breach is required. See Carter v. Nat’l R.R. Passenger
    Corp., 
    63 F. Supp. 3d 1118
    , 1156–57 (N.D. Cal. 2014) (granting summary
    judgment dismissing negligent-training claim because “[p]laintiffs do not
    link any of the evidence [of the errors of an Amtrak train engineer] to any
    specific federal standard of care [for training] . . . or explain how the
    evidence, if credited by the jury, would establish a violation of such a
    standard”); Wimer v. State, 
    841 P.2d 453
    , 455 (Idaho Ct. App. 1992)
    (affirming summary judgment dismissing claim that the state negligently
    trained game officers who charged elk hunters with criminal violations;
    18
    concluding affidavit testimony that the “training and supervision must
    have been deficient because of the manner in which this investigation
    was conducted” was insufficient to support an inference based on a
    “single incident standing by itself” (quoting Anderson v. City of Pocatello,
    
    731 P.2d 171
    , 181 (Idaho 1986))).
    In Inmon v. Crane Rental Services, Inc., the Arizona Court of Appeals
    affirmed a partial summary judgment dismissing a negligent-training
    claim. 
    67 P.3d 726
    , 733 (Ariz. Ct. App. 2003), overruled on other grounds
    by Tarron v. Bowen Mach. & Fabricating, Inc., 
    235 P.3d 1030
    , 1036 (Ariz.
    2010) (en banc). Charles Inmon and Mark Cummings, ironworkers, were
    injured when a loaded crane operated by Eddie De La Torre tipped over
    at their jobsite. 
    Id. at 727–28.
    They sued his employer, a crane rental
    company, alleging it was independently negligent in training him. 
    Id. at 728.
    The plaintiff’s expert testified he “could not say that De La Torre
    was improperly trained, but only that his actions did not demonstrate
    proper training.”   
    Id. at 733.
      The trial court granted the crane rental
    company’s motion for summary judgment on that issue, noting the lack
    of testimony “to indicate what training was omitted” and concluding the
    “[f]ailure to demonstrate competence is not automatically a showing of
    inadequate training.”   
    Id. The appellate
    court agreed and rejected the
    plaintiffs’ argument that the fact finder could infer negligent training,
    stating, “[I]n the absence of facts specifying in what way De La Torre’s
    training or lack thereof was negligent, . . . there is no evidence showing
    that such negligent training was the proximate cause of Plaintiffs’
    injuries.” 
    Id. We see
    the same failure of proof as to Alcala’s negligent-
    training claim.
    Alcala cites no case from any jurisdiction upholding a recovery on a
    record devoid of testimony as to the standard for training for the job at
    19
    issue and devoid of testimony as to how the training fell short. We hold
    it was error to submit negligent training as one of the specifications of
    Marriott’s negligence.    The jury returned a general verdict without
    specifying which grounds of fault Alcala proved. A new trial is required
    after a general verdict is returned for the plaintiff if the evidence was
    insufficient to submit one of several specifications of negligence. Asher v.
    OB-Gyn Specialists, P.C., 
    846 N.W.2d 492
    , 497 (Iowa 2014). That is what
    happened here.
    B. Private Safety Codes.        We conclude a new trial is also
    required based on the district court’s prejudicial error in the jury
    instruction on the ASTM standards. “We have on a number of occasions
    found instructions that unduly emphasized certain evidence were flawed
    and required reversal.”   Burkhalter v. Burkhalter, 
    841 N.W.2d 93
    , 106
    (Iowa 2013); see also Olson v. Prosoco, Inc., 
    522 N.W.2d 284
    , 287 (Iowa
    1994) (“[E]ven instructions correctly stating the law should not give
    undue emphasis to any particular theory, defense, stipulation, burden of
    proof, or piece of evidence.”).   The district court went beyond unduly
    emphasizing certain evidence—the trial judge adopted the position of
    plaintiff’s expert over conflicting testimony of the defense expert in
    Instruction No. 20:
    American Safety and Testing Materials (ASTM)
    Standard Practice for Safe Walking Surfaces requires exterior
    walkways shall be maintained so as to provide safe walking
    conditions (5.7.1). In addition, said standards require that
    exterior walkways shall be slip resistant (5.7.1.1). Finally, if
    an exterior walkway is slippery, it is to be considered
    substandard (5.7.1.2).
    ....
    You may consider a violation of these standards as
    evidence of negligence.
    20
    The defense expert, Bowman, testified the ASTM standard is inapplicable
    to snow and ice removal and instead governs the methods and materials
    used for constructing walkways. Experts for both sides agreed the type
    of slip-resistant, broom-finished concrete used in the construction of
    Marriott’s sidewalk complied with ASTM standards when dry. The only
    reason the sidewalk was slippery was the presence of ice.          Bowman
    further gave uncontroverted testimony that ASTM had considered
    adopting a standard for snow and ice removal but abandoned the idea
    due to lack of agreement on such a standard.           The existing ASTM
    standards do not mention ice or snow.        Yet the jury was essentially
    instructed that an icy sidewalk is substandard.       That is not how we
    interpret the ASTM standard. Alcala cites no case from any jurisdiction
    holding ASTM standard 5.7 is violated when an otherwise compliant
    broom-finished concrete surface is icy, and we found no such case in our
    own research.
    Even assuming the expert testimony was sufficient to generate a
    jury question regarding the applicability of the standard, the district
    court erred by taking one side and telling the jury the standard was
    violated by icy conditions. See Almonte v. Averna Vision & Robotics, Inc.,
    
    128 F. Supp. 3d 729
    , 744 (W.D.N.Y. 2015) (“Usually, when there is a
    factual question about the applicability of two competing industry
    standards, it is for the fact-finder to determine which standard applies.”).
    When experts disagree, the jury should be instructed to decide whether
    the standard applies.       See Rupolo v. Oshkosh Truck Corp., 
    749 F. Supp. 2d 31
    , 43 (E.D.N.Y. 2010) (“[T]he applicability of the ANSI and
    OSHA standards is a factual question. . . . Accordingly, . . . it should be
    for the fact-finder to determine whether [the expert’s] reliance on the
    21
    ANSI and OSHA standards is appropriate.”). The district court erred in
    giving Instruction No. 20, and that error requires a new trial.
    C. The Continuing-Storm Doctrine.            The court of appeals
    majority concluded Marriott was entitled to its requested instruction on
    the continuing-storm doctrine.      The dissenting judge concluded the
    evidence was insufficient to support a jury instruction on the doctrine.
    Because we have determined that the instructional errors discussed
    above require a new trial, we need not decide whether the district court
    erred by refusing Marriott’s requested instruction on the continuing-
    storm doctrine.   We recognize the issue will arise again on remand if
    Marriott renews its request for an instruction on the doctrine.
    We adopted the continuing-storm doctrine in 
    Reuter. 244 Iowa at 943
    , 57 N.W.2d at 227. Quoting from a Virginia case, we established
    the rule that a business establishment, landlord, carrier, or
    other inviter, in the absence of unusual circumstances, is
    permitted to await the end of the storm and a reasonable
    time thereafter to remove ice and snow from an outdoor
    entrance walk, platform, or steps. The general controlling
    principle is that changing conditions due to the pending
    storm render it inexpedient and impracticable to take earlier
    effective action, and that ordinary care does not require it.
    
    Id. (quoting Walker
    , 45 S.E.2d at 902).
    In Rochford, the court of appeals concluded inclement winter
    weather could constitute a storm even if it is not a 
    blizzard. 845 N.W.2d at 718
    .   In that case, however, it was undisputed the plaintiff’s fall
    occurred during freezing rainfall. See 
    id. Thus, the
    holding in Rochford
    does not clearly extend to mist or other precipitation leaving no
    accumulation.
    Iowa courts have applied the continuing-storm doctrine in a few
    other cases. For example, in Wailes v. Hy-Vee, Inc., the court of appeals
    concluded the district court correctly gave a jury instruction on the
    22
    continuing-storm doctrine when the plaintiff challenged the timing of the
    defendant’s snow removal but snow was still falling when the plaintiff
    was injured. 
    861 N.W.2d 262
    , 265–68 (Iowa Ct. App. 2014). We also
    applied the continuing-storm doctrine and granted a defendant judgment
    notwithstanding the verdict when “a trace of snow was recorded” on the
    day of the plaintiff’s fall, “[i]t had been snowing off and on all morning,”
    and “it was still snowing” at the time the plaintiff fell. Hovden v. City of
    Decorah, 
    261 Iowa 624
    , 628, 
    155 N.W.2d 534
    , 537 (1968), superseded by
    statute, 1984 Iowa Acts ch. 1002, § 1.
    This court has acknowledged “[t]he feebleness of human . . . efforts
    in attempting to cope with the power of the elements.” Staples v. City of
    Spencer, 
    222 Iowa 1241
    , 1244, 
    271 N.W. 200
    , 202 (1937).                 The
    continuing-storm doctrine suspends a property owner’s general duty to
    exercise reasonable care in warning of or removing snow and ice hazards
    until a reasonable time after the storm because continually clearing ice
    and snow during an ongoing storm would be impracticable. Reuter, 244
    Iowa at 
    943, 57 N.W.2d at 227
    ; Mattson v. St. Luke’s Hosp. of St. Paul, 
    89 N.W.2d 743
    , 745 (Minn. 1958); 
    Walker, 45 S.E.2d at 902
    .
    Alcala in her application for further review argued for the first time
    that the continuing-storm doctrine is no longer good law under the
    Restatement (Third) of Torts, Liability for Physical and Emotional Harm.
    The parties, however, did not address the impact of the Restatement
    (Third) on the continuing-storm doctrine in their appellate briefs
    preceding the court of appeals decision or in district court before the jury
    was instructed. Neither the district court nor court of appeals addressed
    whether the continuing-storm doctrine should be abandoned in light of
    our adoption of section 7 of the Restatement (Third) of Torts in Thompson
    in 
    2009. 774 N.W.2d at 834
    –35; cf. Crawford v. Extended Stay Am., LLC,
    23
    No. 2007-CA-001127-MR, 
    2008 WL 2610456
    , at *4 (Ky. Ct. App. July 3,
    2008) (Acree, J., concurring) (inviting Kentucky Supreme Court to revisit
    “no-duty” rule for natural snow and ice accumulations in light of section
    7 of the Restatement (Third)). We prefer to wait to decide the issue with
    the benefit of a district court ruling and full adversarial briefing.
    Accordingly, we decline to decide it now. See Hagenow v. Schmidt, 
    842 N.W.2d 661
    , 677 (Iowa 2014) (“[N]either the parties nor the district court
    raised the provisions of the Restatement (Third) when instructing the
    jury in this case. We defer for another day our consideration of these
    provisions . . . .”). The parties are free to brief and argue that issue on
    remand and may develop a different evidentiary record on weather
    conditions in the new trial.
    IV. Disposition.
    For the foregoing reasons, Marriott is entitled to a new trial. We
    vacate the decision of the court of appeals, reverse the district court
    judgment, and remand the case for a new trial consistent with this
    opinion.
    DECISION OF COURT OF APPEALS VACATED; DISTRICT
    COURT JUDGMENT REVERSED AND CASE REMANDED FOR NEW
    TRIAL.
    All justices concur except Hecht, Wiggins, and Appel, JJ., who
    concur in part and dissent in part.
    24
    #14–1058, Alcala v. Marriott Int’l, Inc.
    HECHT, Justice (concurring in part and dissenting in part).
    I join Part II of the majority opinion clarifying that the scope of
    review regarding refusal to give a requested jury instruction is for
    correction of errors at law. Beyond that threshold question, however, the
    majority and I part ways significantly.               I dissent because I find no
    reversible error in either of the jury instructions Marriott challenges on
    appeal.      I also conclude the district court correctly declined on this
    record to submit the instruction proposed by Marriott on the continuing-
    storm doctrine. I would vacate the decision of the court of appeals and
    affirm the judgment the district court entered on the jury’s verdict.
    I. Negligent Training.
    The law governing this issue is well established. “In considering
    whether [an] instruction is supported by substantial evidence, we give
    the evidence the most favorable construction it will bear in favor of
    supporting the instruction.”           Asher v. OB-Gyn Specialists, P.C., 
    846 N.W.2d 492
    , 496–97 (Iowa 2014). The majority orders a new trial in part
    because it concludes no testimony established the parameters of
    Marriott’s duty to exercise reasonable care in training its employees on
    proper approaches in removing ice from sidewalks.                         But Marriott
    concedes it owed a duty.4 Its objection to the training specification of
    4It  comes as no surprise that Marriott did not deny it owed a duty to exercise
    reasonable care in training its employees on the subject of removing ice from its
    sidewalks. Under section 7(a) of the Restatement (Third) of Torts, an “actor ordinarily
    has a duty to exercise reasonable care when the actor’s conduct creates a risk of
    physical harm.” 1 Restatement (Third) of Torts: Liab. for Physical & Emotional Harm
    § 7(a), at 77 (2010) [hereinafter Restatement (Third)]; see Thompson v. Kaczinski, 
    774 N.W.2d 829
    , 835 (Iowa 2009) (adopting the Restatement (Third)’s duty framework).
    “Thus, in cases involving physical harm, courts ordinarily need not concern themselves
    with the existence or content of this ordinary duty. They may proceed directly to the
    elements of liability . . . .” 1 Restatement (Third) § 6 cmt. f, at 69. Those four elements
    of a prima facie claim for negligence are “(1) failure to exercise reasonable care;
    25
    negligence was instead that Alcala failed to present substantial evidence
    of a breach of that duty.
    Alcala did not present expert testimony on the standard of care
    hotels must meet in training their employees on proper snow and ice
    removal techniques or on Marriott’s breach of that duty.                  In my view,
    however, expert testimony was not required on these subjects.                      “The
    question of what a reasonable person would do . . . in training and
    supervising employees is one permissibly resolved on the basis of the
    knowledge and experience of lay persons.”              Graves v. N.E. Servs., Inc.,
    
    345 P.3d 619
    , 628 (Utah 2015).5
    Some weather-related phenomena are clearly within a layperson’s
    understanding:
    _________________________
    (2) factual cause; (3) physical harm; and (4) harm within the scope of liability (which
    historically has been called ‘proximate cause’).” 
    Id. § 6
    cmt. b, at 67–68. Thus, Alcala
    had no burden to present express testimony that Marriott owed a duty to exercise
    reasonable care in training its employees on the proper methods of clearing ice from its
    sidewalks.
    5Although   expert testimony was not required to justify submission of the issue
    to the jury, it would of course have been admissible. In a 1963 slip-and-fall case where
    the fall occurred on an indoor dance floor, we concluded a court properly admitted
    expert testimony from those familiar with “care of waxed floors and the safe practices in
    wax application thereon.” Smith v. Cedar Rapids Country Club, 
    255 Iowa 1199
    , 1210,
    
    124 N.W.2d 557
    , 564 (1963). The testimony was helpful because it aided jurors in
    understanding the interplay between the particular chemical used and the material
    comprising the dance floor on which the injury occurred, as well as “the proper
    application and slipperiness of” the floor wax. 
    Id. at 1211,
    124 N.W.2d at 564.
    However, Smith does not stand for the proposition that expert testimony was required in
    this case on the question whether Marriott breached its duty to train its employees
    properly. First, I believe laypeople are more familiar with ice, deicer, and concrete
    sidewalks than the properties of the floor wax when applied to the flooring material at
    issue in that case. Second, and more importantly, we concluded in Smith only that
    expert testimony was permissible, not that it was required to engender a jury question.

    567 N.W.2d 431
    , 437 (Iowa 1997) (concluding expert testimony about crossing guard
    training was sufficient—not that it was required—to support a failure-to-train
    specification of negligence).

    We know that it is dangerous to be in or near certain
    structures, or even trees, during lightning storms. We also
    know that, if we are in an area of high lightning frequency,
    we should be cautious, and that the height of the structures
    in relation to the surrounding terrain might attract lightning.
    In other words, . . . risk assessment factors [regarding
    lightning damage protection] [a]re not complicated or novel
    ideas or even foreign to a layperson’s understanding about
    the phenomenon of lightning.

    564 N.W.2d 376
    , 381 (Iowa 1997). Similarly, a
    plaintiff need not present an engineer to opine that stacking logs
    haphazardly might result in the pile toppling over and injuring a
    bystander:
    Where the construction of a given pile of timber is properly
    explained, it appears to us that a jury of [people] not
    especially experienced in piling timber would have no
    difficulty in forming an opinion for themselves as to the
    liability of the pile to fall and injure a person who should be
    near it. Such work, it seems to us, does not in any proper
    sense involve the mystery of technical knowledge or skill.

    68 Iowa 37
    , 39, 
    25 N.W. 918
    , 919
    (1885).   Likewise, I would hold deicer’s durational effectiveness and
    Marriott’s duty to address the subject when training its employees on
    proper techniques for removing ice from sidewalks does not require
    expert testimony.   Information on the durational effectiveness of the
    deicer Marriott used is discernable from the product manufacturer
    without special knowledge, education, or expertise. Indeed, Bowman—
    an expert in architecture but a layperson with respect to commercial
    snow and ice removal—demonstrated his ability to discern the durational
    effectiveness simply by reading available product literature. See Spencer
    v. Wal-Mart Stores E., LP, 
    930 A.2d 881
    , 888–89 (Del. 2007) (noting an
    architect was not “an expert on ice and snow removal”).
    I now turn to the question of whether the record—when viewed in
    the light most favorable to the instruction, see 
    Asher, 846 N.W.2d at 27
    496–97—includes substantial evidence of a breach of Marriott’s duty to
    properly train its employees. Unlike the majority, I conclude the record
    does include evidence from which the jury could find Marriott breached
    its duty to exercise reasonable care in training.
    The evidence on the condition of Marriott’s sidewalk and the
    presence of adequate quantities of deicer is conflicting and greatly in
    dispute. DePaepe testified there was already “salt all over the sidewalks”
    when she arrived for her overnight shift at 10:00 p.m. on January 20.
    Although a reasonable fact-finder could find on this record that there
    was no new measurable precipitation during her shift, DePaepe
    testified—and her nightly checklist represents—that she applied more
    deicer three times during her eight hours: from 12:03 to 12:20 a.m., 2:29
    to 2:59 a.m., and 5:24 to 5:40 a.m.        If Bowman’s testimony that the
    deicer generally remains effective for three to four hours is correct, and
    DePaepe’s testimony is true, any failure to train DePaepe about
    durational effectiveness of the deicer arguably did not cause Alcala’s
    injury because DePaepe testified she reapplied the deicer within the
    product’s durational effectiveness.
    But the jury was entitled to make credibility determinations and
    sort out conflicts in the evidence. DePaepe testified there was plenty of
    deicer on the sidewalk both when she arrived at 10:00 p.m. on
    January 20 and when she left after 6:00 a.m. on January 21. Marriott’s
    operations manager testified she remembered the deicer granules
    crunching under her boots as she entered the building around 7:00 a.m.
    on January 21. However, other evidence tended to show that at the time
    Alcala fell, the sidewalk was treacherously slick. The paramedics who
    responded to the 911 call testified they “had a hard time getting to”
    Alcala and “were having a hard time staying” upright themselves. One
    28
    even testified the sidewalk was “eight or higher” on a ten-point
    slipperiness scale and that the fire department dispensed its own
    chemical to provide the paramedics with better traction. Furthermore,
    another witness who was a guest at the Marriott testified that when he
    left the hotel just before Alcala, the sidewalk was so slippery that he
    opted to walk on the adjacent grass instead to avoid falling.
    A reasonable juror could infer from this conflicting evidence that
    DePaepe did not apply the deicer with the frequency she claimed.         A
    reasonable fact finder could also find from DePaepe’s testimony that she
    had not been trained on the deicer’s durational effectiveness. The jury
    could find that had DePaepe been provided this information during
    training or instructed to seek out such information and follow it, she
    would have understood any deicer applied before 3:00 a.m. (and certainly
    before 10:00 p.m. the night before) would no longer be effective after four
    hours if temperatures remained around freezing.        In other words, if
    DePaepe’s testimony about distribution of the deicer and the condition of
    the sidewalk at material times was rejected as not credible in whole or in
    part, the jury could have found on this record that her failure to apply
    the deicer properly was a result of Marriott’s inadequate training on the
    durational effectiveness of the deicer.   Put yet another way, the jury
    could have found that DePaepe did not apply the deicer in a timely
    fashion because she was not properly trained on its durational
    effectiveness.   This conclusion would require the jury to make several
    inferences, but fact finders properly utilize inferences in almost every
    case.
    I also reject the majority’s conclusion that a jury question on
    negligent training must fail because Alcala did not offer express
    testimony that Marriott breached its duty to exercise reasonable care in
    29
    training its employees.    All manner of negligence claims that do not
    require expert testimony to establish a standard of care are submitted to
    juries—and have been for decades—without express testimony from a
    witness that the defendant breached a duty owed to the plaintiff. For
    example, in automobile negligence cases, trial judges commonly submit a
    specification of negligence on the duty to keep a proper lookout without
    express testimony—lay or expert—that the defendant breached the duty.
    See, e.g., Graber v. City of Ankeny, 
    616 N.W.2d 633
    , 643–44 (Iowa 2000)
    (concluding the record contained sufficient evidence to support an
    instruction on proper lookout when both drivers testified about what
    they saw immediately before the collision); Luther v. Jones, 
    220 Iowa 95
    ,
    103, 
    261 N.W. 817
    , 821 (1935) (concluding the trial court correctly
    submitted proper lookout to the jury even though there was “no
    evidence, aside from the fact of the accident, that [the defendant] failed to
    keep a proper lookout”).
    Similarly, in premises liability cases against grocers, specifications
    of negligence are commonly submitted to juries without express
    testimony that grocers breached the duty to keep walkways free of
    hazards. See, e.g., W. Supermarkets, Inc. v. Keith, 
    528 So. 2d 317
    , 320–
    21 (Ala. 1988) (concluding a negligence claim was properly submitted to
    the jury based on the plaintiff’s testimony about what she observed and
    the store employees’ testimony that they swept and cleaned at regular
    intervals); Strack v. Great Atl. & Pac. Tea Co., 
    150 N.W.2d 361
    , 363 (Wis.
    1967) (concluding a jury’s finding that a store “failed to inspect and
    sweep within a reasonable time before the accident” had “adequate
    support in the evidence” even though there was “no direct testimony
    establishing the Italian prune [on which the plaintiff slipped] was on the
    floor” for a lengthy period). Just as the court in Strack did not require
    30
    the plaintiff to produce express testimony that the defendant grocer
    breached its duty to keep its aisles safe for customers by leaving a prune
    on the floor too long, Alcala had no burden to produce testimony that
    Marriott breached its duty to properly train DePaepe when it failed to
    train her on the durational effectiveness of the deicing compound she
    was required to use on the company’s sidewalks. And just as we do not
    require a plaintiff to produce express testimony that the defendant failed
    to keep a proper lookout while driving her car at the time of a crash,
    Alcala had no burden to produce express testimony on Marriott’s breach
    of its duty to train DePaepe in this case.
    I acknowledge the jury could conclude on this record that DePaepe
    was credible and that she dutifully applied deicer three times during her
    shift at the times she recorded on her checklist. But in evaluating the
    sufficiency of the evidence supporting a jury instruction, “we give the
    evidence the most favorable construction it will bear in favor of
    supporting the instruction.”    
    Asher, 846 N.W.2d at 496
    –97.       Perhaps
    Alcala could have presented more evidence supporting the improper
    training specification of negligence, but what she did present—testimony
    permitting the jury to conclude DePaepe was not trained on the
    durational effectiveness of the deicing compound—was in my view at
    least minimally sufficient to engender a jury question on the training
    specification of negligence. I would therefore hold the district court did
    not err in submitting Instruction 16.
    II. Private Industry Standards as Evidence of Negligence.
    I also disagree with the majority’s conclusion that the district court
    erred in giving Instruction 20. The majority holds that because Russell
    Kendzior and Alan Bowman provided different opinions as to the
    industry safety standards’ applicability, the district court should have
    31
    permitted the jury to determine whether the ASTM and ANSI standards
    were applicable.     This conclusion misunderstands the allocation of
    responsibility between the court and the jury on the issues of duty and
    breach.
    While industry standards may have “no legislative sanction, it is
    difficult to conceive a better test of care than compliance with [their]
    provisions.” Smith v. Iowa Pub. Serv. Co., 
    233 Iowa 336
    , 337, 
    6 N.W.2d 123
    , 123 (1942). As the New Jersey Supreme Court has explained,
    A safety code ordinarily represents a consensus of opinion
    carrying the approval of a significant segment of an industry.
    Such a code is not introduced as substantive law, as proof of
    regulations or absolute standards having the force of law or
    of scientific truth. It is offered in connection with expert
    testimony which identifies it as illustrative evidence of safety
    practices or rules generally prevailing in the industry, and as
    such it provides support for the opinion of the expert
    concerning the proper standard of care.
    McComish v. DeSoi, 
    200 A.2d 116
    , 120–21 (N.J. 1964). In other words,
    industry   standards,    if   relevant,   properly   inform    the   court’s
    determinations whether the defendant owes a duty to the plaintiff and
    what that duty is.
    The existence of a legal duty and the scope of that duty are
    questions of law for the court, not questions of fact for the jury. See,
    e.g., Van Fossen v. MidAmerican Energy Co., 
    777 N.W.2d 689
    , 693 (Iowa
    2009); Sweeney v. City of Bettendorf, 
    762 N.W.2d 873
    , 880 (Iowa 2009);
    see also 1 Restatement (Third) of Torts: Liab. for Physical & Emotional
    Harm § 6 cmt. b, at 67 (2010) [hereinafter Restatement (Third)]. Thus,
    the court—not the jury—must decide whether a proffered industry
    standard is applicable to a given set of facts. See Hansen v. Abrasive
    Eng’g & Mfg., Inc., 
    856 P.2d 625
    , 628 (Or. 1993) (en banc) (discussing an
    ANSI standard and noting “[d]etermination of the appropriate standard of
    32
    care is an issue of law”). “ ‘[A]pplicability’ connotes no . . . compulsion to
    conform with a particular standard. Rather, ‘applicability’ connotes mere
    relevance . . . .” Keller v. United States, 
    38 F.3d 16
    , 26 (1st Cir. 1994)
    (citation omitted). Typically the court determines applicability of industry
    standards through rulings in advance of trial or relevance objections
    during trial. If a standard has no application to the circumstances of the
    case, it is irrelevant to the court’s duty analysis. See Aller v. Rodgers
    Mach. Mfg. Co., 
    268 N.W.2d 830
    , 840–41 (Iowa 1978) (affirming a trial
    court’s exclusion of some industry safety standards, in part because
    some of the standards were for completely different industries and
    therefore irrelevant).
    Marriott notably did not challenge the applicability of ASTM
    Standard F1637 or ANSI Standard A1264.2 in its motion in limine, nor
    did it make a relevance objection at trial when Kendzior relied on the
    standards during his testimony. Instead, Marriott chose to contest the
    standards’ applicability through Bowman’s expert opinion.           Bowman
    opined the standards were not applicable to Marriott because they were
    not binding through state law or a municipal ordinance and because
    they were developed primarily to address employee—not pedestrian—
    traction and safety. Both of Bowman’s opinions are without merit.
    The ASTM and ANSI standards discussed in this case “have not
    been given the force of law.” See Jorgensen v. Horton, 
    206 N.W.2d 100
    ,
    103 (Iowa 1973) (concluding industry standards are “not conclusive on
    the issue of negligence”). But Alcala did not assert negligence per se, so
    the fact the industry standards do not carry the force of law does not
    mean they have no relevance in this case. See 
    Hansen, 856 P.2d at 628
    (concluding an ANSI standard was “relevant to the jury’s consideration of
    whether defendant met the standard of care” even though the standard
    33
    was “purely advisory and not binding on anyone”); see also Kent Vill.
    Assocs. Joint Venture v. Smith, 
    657 A.2d 330
    , 337 (Md. Ct. Spec. App.
    1995) (concluding “the fact that [an ANSI s]tandard has not been
    officially adopted as a regulation” did not “destroy its relevance as
    articulating a standard of care”). The majority erroneously attributes a
    negligence per se claim to Alcala when it states the district court told the
    jury the standard was violated by icy conditions. The district court did
    no such thing; it merely told the jury what the standard says and
    permitted the jury to conclude a violation, if one occurred, was some
    evidence of negligence.
    Likewise, Bowman’s opinion that the standards primarily address
    employees and not pedestrians does not preclude their relevance to the
    existence of a duty or its breach in this case.      By analogy, although
    OSHA regulations normally set forth an obligation only between
    employers and employees, a violation of OSHA regulations is “evidence of
    negligence as to all persons who are likely to be exposed to injury as a
    result of the violation,” even if the person exposed to injury is not an
    employee.   Koll v. Manatt’s Transp. Co., 
    253 N.W.2d 265
    , 270 (Iowa
    1977); see also Smith v. Kris-Bal Realty, Inc., 
    576 A.2d 934
    , 938 (N.J.
    Super. Ct. App. Div. 1990) (“[T]he OSHA code . . . may be relied upon to
    illustrate industry standards and to provide support for the opinion of an
    expert on the proper standard of care . . . even though plaintiff was a
    business guest at the marina, not a worker.”). The same principle is true
    here. Even if the ASTM and ANSI standards primarily address employee
    safety, “there are numerous areas traversed by both” employees and
    hotel guests—like the outdoor walkway on which Alcala fell. Sorrels v.
    NCL (Bahamas) Ltd., 
    796 F.3d 1275
    , 1282 (11th Cir. 2015). Accordingly,
    even assuming Bowman’s opinion as to the primary purpose of the
    34
    standards is correct, it would not make them irrelevant in determining
    whether Marriott owed a duty of reasonable care to Alcala under the
    circumstances of this case. See 
    id. at 1283.
    The determination of whether a proffered industry standard is
    relevant to the existence of a duty under a given set of facts is a question
    of law for the court—not the jury. See 
    Hansen, 856 P.2d at 628
    . Thus,
    in deciding the relevance of industry standards to the existence of a
    defendant’s duty, the district court must make the decision—as the
    district court did in this case—even when presented with conflicting
    expert testimony.     Some courts conclude industry standards are
    applicable and some conclude they are not, depending on the
    circumstances of the case—but the court decides the question of their
    relevance.   Compare Briere v. Lathrop Co., 
    258 N.E.2d 597
    , 604 (Ohio
    1970) (concluding the trial judge did not err in determining industry
    standards were inapplicable “[i]n light of the conflicting testimony about
    industry adherence to the [proffered] rules”), and Landsiedel v. Buffalo
    Props., LLC, 
    112 P.3d 610
    , 617 (Wyo. 2005) (finding no reversible error in
    the trial court’s “decision not to accept . . . industry standards as
    defining the minimum standard of care” given the parties’ conflicting
    evidence as to the standards’ applicability), with Dixon v. Int’l Harvester
    Co., 
    754 F.2d 573
    , 582 (5th Cir. 1985) (“Although the testimony was in
    dispute there was substantial evidence to indicate the relevancy of the
    ANSI standards . . . .”), and Eagleburger v. Emerson Elec. Co., 
    794 S.W.2d 210
    , 231 (Mo. Ct. App. 1990) (en banc) (concluding a decision on ANSI
    standards’ relevance “was a determination to be made by the trial court”
    even though “there was substantial evidence by plaintiffs that the ANSI
    35
    standards applied . . . and substantial evidence by [the defendant] that
    they did not”).6
    By giving Instruction 20 in this case, the district court clearly
    concluded the ASTM and ANSI standards were applicable and therefore
    relevant to the existence of Marriott’s duty under the circumstances of
    this case. The majority concludes the instruction was erroneous because
    it means the court adopted Kendzior’s opinion on applicability over
    Bowman’s.      But because the court, not the jury, decides whether the
    standards are relevant, that was its prerogative, and because the experts
    in this case were completely at odds, the district court could not have
    adopted both experts’ views on relevance.               Furthermore, even when a
    court    concludes     industry     standards     are    applicable,    it   does    not
    automatically follow that the court credits an expert’s opinion as to
    breach of those standards.          See 
    Keller, 38 F.3d at 29
    .           A jury could
    conclude, for example, that noncompliance with relevant industry
    standards “was excusable, and therefore not negligent.” Morgan v. State,
    
    862 P.2d 1080
    , 1083 (Idaho 1993).
    I conclude Kendzior’s expert testimony is substantial evidence
    amply supporting the district court’s determination that the standards
    6I acknowledge the highest court in New York has reached a different
    conclusion. See Sawyer v. Dreis & Krump Mfg. Co., 
    493 N.E.2d 920
    , 925 (N.Y. 1986)
    (“The ANSI requirements . . . could be considered by the jury as some evidence of
    negligence if it first found that the standards set forth in the booklet represented the
    general custom or usage in the industry.”). Accordingly, federal district courts applying
    New York law have also left the question of relevance of industry standards to the jury.
    See Almonte v. Averna Vision & Robotics, Inc., 
    128 F. Supp. 3d 729
    , 744 (W.D.N.Y.
    2015); Rupolo v. Oshkosh Truck Corp., 
    749 F. Supp. 2d 31
    , 43 (E.D.N.Y. 2010). My
    research reveals that many other courts addressing the question take a different
    approach allocating to the court the responsibility of deciding the relevance of industry
    standards to the existence of a duty. I find that approach consistent with the
    traditional allocation of responsibility between the court and the jury and would
    therefore adopt it in this case.
    36
    were relevant to Marriott’s duty to exercise reasonable care.                   Having
    clarified the question of relevance of the standards was a question of law
    for the court, not a question of fact for the jury, I now turn to consider
    whether the court committed legal error by concluding ASTM Standard
    F1637 and ANSI Standard A1264.2 were relevant to the duty issue in
    this case.
    My analysis of this question is slightly more difficult than it might
    be in other cases because neither party marked the ASTM and ANSI
    standards and caused them to be made part of the record. Nonetheless,
    the trial transcript reveals they were presented to the court and shown to
    the jury via a projector during Kendzior’s testimony. Kendzior read from
    the standards and Instruction 20 contains verbatim language from them.
    Additionally, the standards’ substance is published and available to this
    court. Thus, this is not a case where “the content of the [standard]s is
    not specified,” which might make us “unable to determine from the
    record before us the relevance of the sections cited.” Gerace v. 3-D Mfg.
    Co., 
    522 N.W.2d 312
    , 318–19 (Iowa Ct. App. 1994).
    While    we    often    address      industry     standards     in    terms    of
    admissibility, I conclude admission of them as an exhibit is not a
    condition precedent to their applicability and their relevance to the
    court’s determination of the existence of a legal duty.7 I find support for
    this conclusion in three cases.
    In a Colorado case, the parties debated whether OSHA regulations
    were applicable. Scott v. Matlack, Inc., 
    39 P.3d 1160
    , 1168 (Colo. 2002)
    7Although   admitting industry standards as an evidentiary exhibit is not a
    condition precedent to the court’s consideration of them in its determination of the duty
    question, I encourage the bench and bar in future cases to mark and identify them for
    inclusion in the record.

    (en banc). “Specific regulations were not entered into evidence but were
    discussed extensively by various witnesses.”     
    Id. The court
    concluded
    “the jury should be permitted to hear evidence of [OSHA] regulations as
    some indication of the standard of care.” 
    Id. at 1170
    (emphasis added).
    The court spoke in terms of “admitting evidence,” but it is clear the
    evidence came solely—and permissibly—through testimony, not through
    an evidentiary exhibit. See 
    id. at 1164,
    1170.
    In a Missouri case, an expert was “not allowed to cite . . . specific
    [standard]s” but did testify that “ANSI standards exist . . . and that he
    reviewed and considered those standards” in forming his opinion.
    Ratcliff v. Sprint Mo., Inc., 
    261 S.W.3d 534
    , 550 (Mo. Ct. App. 2008). The
    Ratcliff court found no reversible error resulted from the ruling
    precluding the expert’s reference to specific standards because the jury
    heard their substance through the expert’s testimony. See 
    id. Finally, we
    have noted that private safety codes are on occasion a
    subject of trial testimony even when documents evidencing them are not
    received in evidence.   See Isaacs v. E. Iowa Light & Power Coop., 
    236 Iowa 402
    , 408, 
    19 N.W.2d 208
    , 211 (1945).        In Isaacs, we noted the
    appellate record did not show a private safety code was offered into
    evidence.   See 
    id. at 408,
    19 N.W.2d at 211.     We concluded that fact
    alone resulted in no reversible error given that “some reference in the
    testimony to said code” was permitted and because compliance with the
    private safety code was not determinative of the defendant’s compliance
    with the standard of care. See 
    id. at 408–09,

    848 (1965) (concluding “[a]ctionable negligence may exist even though” a
    defendant complies with an industry standard or private safety code).
    38
    I conclude Alcala adequately presented the ASTM and ANSI
    standards at issue in this case in the district court so that the court
    could determine whether they were relevant to the existence of Marriott’s
    duty of care. Cf. Porter v. Omni Hotels, Inc., 
    579 S.E.2d 68
    , 71 (Ga. Ct.
    App. 2003) (concluding a plaintiff did not show an ANSI standard applied
    when he neither placed the standard into evidence nor presented expert
    testimony regarding the standard).
    After reviewing the language of the standards discussed by the
    experts at trial and incorporated in Instruction 20, I would hold the
    district court did not err in finding them applicable and relevant to
    Marriott’s duty of care. The ANSI standard clearly addresses snow and
    ice removal from pedestrian walkways.            It is not part of a statute or
    ordinance, but the district court instructed the jury only that it could
    consider violation of the standard as evidence of negligence.
    The ASTM standard is a closer question.               Marriott contends
    Standard F1637 addresses only construction materials and design, so
    the notion that walkways must be slip resistant and that a slippery
    exterior walkway is substandard evaluates only the characteristics of the
    construction material used to build the walkway (in this case concrete),
    not any effects of weather on the walkway.            That position has some
    intuitive   appeal,   but   section   1.1   of   Standard   F1637    addresses
    construction     standards     and    “minimum        maintenance     criteria.”
    Furthermore, the standard also provides walkways should be slip
    resistant under “expected environmental conditions and use.” Notably,
    the standard does not expressly exclude from its scope this particular
    class of persons, property, or circumstances. Cf. Lynch v. Reed, 
    944 P.2d 218
    , 224 (Mont. 1997) (concluding an ANSI construction standard was
    inapplicable because the provision setting forth the scope of the standard
    39
    expressly stated the standard did not apply to residential projects);
    Kalish v. HEI Hosp., LLC, 
    980 N.Y.S.2d 80
    , 82 (App. Div. 2014) (noting
    Standard F1637 “specifically identif[ies] bath tubs and showers as
    beyond the scope of the practices contained therein”).           Nor is the
    standard obviously inapplicable because it is directed at an entirely
    different industry. Cf. 
    Aller, 268 N.W.2d at 840
    –41 (concluding “safety
    standards in the metalworking industry” were inapplicable and irrelevant
    in a case involving the woodworking industry). Although ASTM Standard
    F1637 is couched in much more general terms than the ANSI standard, I
    conclude the district court did not err in finding it relevant to the court’s
    determination of Marriott’s duty and to the jury’s determination of
    negligence.    See Williams v. Crane, No. 2:14-CV-241 TS, 
    2015 WL 7176370
    , at *2 (D. Utah Nov. 13, 2015) (concluding, in a slip-and-fall
    case involving snow and ice, that “the ASTM Standard Practice for Safe
    Walking Surfaces”—which is number F1637—“may be helpful to the jury
    in determining reasonable safety practices for safe walking surfaces”).
    Accordingly, the district court did not err in giving Instruction 20.
    C.      Continuing Storm.       The district court concluded the
    continuing-storm doctrine had no application under the facts of this case
    and declined Marriott’s request for an instruction. Although the majority
    does not reach this issue, I conclude that, even without reaching the
    doctrine’s continued vitality under the Restatement (Third), the district
    court did not err and should be affirmed.
    We adopted the continuing-storm doctrine in 1953. Reuter v. Iowa
    Tr. & Sav. Bank, 
    244 Iowa 939
    , 943, 
    57 N.W.2d 225
    , 227 (1953).              I
    generally agree with the majority’s recitation of the history of the doctrine
    in Iowa, but I offer one additional point: There is a difference between a
    claim challenging the timing of snow removal efforts and a claim
    40
    challenging the manner of snow removal efforts. Wailes v. Hy-Vee, Inc.,
    
    861 N.W.2d 262
    , 267 (Iowa Ct. App. 2014).          A claim challenging the
    manner of snow removal is not subject to the continuing-storm doctrine
    because it merely seeks to enforce “the general rule that an actor
    ordinarily has a duty to exercise reasonable care when the actor’s
    conduct creates a risk of physical harm.” Id.; see 1 Restatement (Third)
    § 7(a), at 77; see also Robinson v. Park Cent. Apartments, 
    248 F. Supp. 632
    , 635 (D.D.C. 1965) (“The defendants undertook the task of clearing
    the sidewalk . . . . Even if there was no legal duty to do so, once a person
    voluntarily undertakes to perform a task, he [or she] is held to the
    requirement that it should be done free of negligence . . . .”); Estep v. B.F.
    Saul Real Estate Inv. Tr., 
    843 S.W.2d 911
    , 914 (Ky. Ct. App. 1992) (“In
    this case, [the land occupiers] opted to attempt to clear their lot and
    sidewalks of ice and snow . . . . Since they chose to so act, they must act
    in a reasonable manner or be liable for their failure.”); Danner v. Myott
    Park, Ltd., 
    306 N.W.2d 580
    , 583 (Neb. 1981) (reversing a verdict in a
    defendant’s favor, remanding for new trial, and disapproving of the
    continuing-storm instruction the trial court gave because it erroneously
    allowed the jury to find “that improper clearing of snow and ice . . . was
    of no consequence because defendant had a right to wait until the end of
    the storm before doing anything at all”). Because I conclude the evidence
    here did not justify a continuing-storm instruction in any event, I find it
    unnecessary to decide whether Alcala challenges the timing or manner
    (or both) of Marriott’s snow and ice removal.
    41
    We have not had occasion to define the word “storm” precisely,8
    nor have we prescribed an outer limit of what might be considered a
    reasonable time for removing snow or ice from walkways after a storm
    ends under the continuing-storm doctrine.            See Frykman v. Univ. of
    Minn.—Duluth, 
    611 N.W.2d 379
    , 381 (Minn. Ct. App. 2000) (declining to
    resolve a case as a matter of law because the facts did not establish “a
    clear-cut storm incident”); see also Batie v. City of Humboldt, 
    228 Iowa 528
    , 532–33, 
    292 N.W. 857
    , 859 (1940) (declining, in a pre-Reuter case,
    to conclude three hours between the end of a snowstorm and a plaintiff’s
    fall was as a matter of law an unreasonable delay in addressing the
    hazard).   However, in considering whether the evidence in this case
    supports Marriott’s requested continuing-storm instruction, I keep in
    mind the rule’s purpose and animating principle, as this court does in
    many other contexts.       See, e.g., Baker v. Bridgestone/Firestone, 
    872 N.W.2d 672
    , 678 & n.4 (Iowa 2015) (acknowledging the longstanding
    principle that the “humanitarian and beneficent purpose” of workers’
    compensation statutes informs our interpretation of them); Iowa
    Supreme Ct. Att’y Disciplinary Bd. v. Howe, 
    706 N.W.2d 360
    , 378 (Iowa
    2005) (keeping in mind “the underlying purposes of attorney discipline”
    when determining a sanction for ethical misconduct); Renander v. Inc.,
    Ltd., 
    500 N.W.2d 39
    , 42 (Iowa 1993) (declining to interpret a statute to
    “expand the legislature’s narrow purpose”).
    The rule’s purpose is essentially to prevent land occupiers from
    having to undertake Sisyphean tasks every time it snows. See Reuter,
    244 Iowa at 
    943, 57 N.W.2d at 227
    . But not every weather event thwarts
    8In particular, we have not been called upon to decide how severe a weather
    event must be to support a continuing-storm instruction.
    42
    cleanup. See Powell v. MLG Hillside Assocs., L.P., 
    737 N.Y.S.2d 27
    , 29
    (App. Div. 2002). “[I]f the storm has passed and precipitation has tailed
    off to such an extent that there is no longer any appreciable
    accumulation, then the rationale for continued delay abates, and
    common sense would dictate that the rule not be applied.” 
    Id. A weather
    event not presenting an ongoing deluge of subzero temperatures and
    blowing and drifting snow, see Olejniczak v. E.I. du Pont de Nemours &
    Co., 
    79 F. Supp. 2d 209
    , 217 (W.D.N.Y. 1999), freezing rain, see Rochford
    v. G.K. Dev., Inc., 
    845 N.W.2d 715
    , 718 (Iowa Ct. App. 2014), or slush
    and snow pedestrians might track into a building’s vestibule, see Parsons
    v. H.L. Green Co., 
    233 Iowa 648
    , 648–49, 
    10 N.W.2d 40
    , 41 (1943), does
    not present the kinds of changing conditions the continuing-storm
    doctrine addresses. See Reuter, 244 Iowa at 
    943, 57 N.W.2d at 227
    .
    Courts in other jurisdictions have addressed allegedly ongoing
    storms and concluded a lack of changing conditions might render the
    continuing-storm doctrine inapplicable.      For example, in Powell, the
    court found it important in rejecting the doctrine’s application that “there
    was nothing more than trace amounts of precipitation during the two
    hour and 20 minute period . . . prior to the 
    accident.” 737 N.Y.S.2d at 29
    .   In another New York case, the court questioned whether the
    analogous storm-in-progress rule applied when there was a two-hour
    window “between the cessation of freezing rain and the accident” during
    which normal (not freezing) rain fell.   Vosper v. Fives 160th, LLC, 
    973 N.Y.S.2d 589
    , 590 (App. Div. 2013).
    Of course, the continuing-storm doctrine “does not foreclose
    submission to the jury, on a proper evidentiary foundation, of the factual
    determination[] of whether a storm has ended.” Kraus v. Newton, 
    558 A.2d 240
    , 243–44 (Conn. 1989).        In one Connecticut case, the court
    43
    found sufficient the evidentiary foundation for a requested continuing-
    storm instruction because “climatological records . . . detailed a number
    of different types of weather between 7 a.m. and 4 p.m. on the day of the
    plaintiff’s fall, including light snow, freezing rain, heavy rain, light rain
    and mist.”     Umsteadt v. G.R. Realty, 
    1 A.3d 243
    , 248 (Conn. App. Ct.
    2010). However, when I evaluate this record while keeping in mind the
    continuing-storm doctrine’s purpose, I conclude the district court
    correctly rejected the proposed instruction in this case.
    The certified weather records in this case unquestionably show
    mist continuing from January 20 through the morning of January 21 in
    Moline and mist at some point on January 21 in Davenport. While those
    locations are a few miles from Bettendorf, we have long acknowledged
    that a certified weather record from a nearby observation point is
    “competent and relevant” evidence “for the purpose of showing the
    temperature and snowfall during the time it purport[s] to cover.” Huston
    v. City of Council Bluffs, 
    101 Iowa 33
    , 39, 
    69 N.W. 1130
    , 1131 (1897)
    (accepting weather records from Omaha, Nebraska as indicative of
    weather in Council Bluffs, Iowa during the same time). But the mist did
    not   present    the   types   of    changing    conditions   undergirding   the
    continuing-storm doctrine.          By 7:00 p.m. on January 20, over twelve
    hours before Alcala fell, the weather system was no longer producing
    measurable quantities of precipitation in nearby Moline and Davenport;
    nor did it feature other phenomena—like strong gusts of wind or blowing
    snow—that would have made cleanup and sidewalk safety precautions
    impractical.
    Meteorological      data       from     nearby   Moline    indicates   no
    accumulations of precipitation after 7:00 p.m. on January 20. At most,
    the data from Davenport indicates a trace amount of precipitation was
    44
    observed on January 21.        But the Davenport data lacks temporal
    specificity, so if the district court had given Marriott’s requested
    instruction, the jury would have had to speculate that the trace accruing
    on   January   21   occurred    before   Alcala   fell   around   8:00   a.m.
    “[S]peculation is not substantial evidence.” Sleeth v. Louvar, 
    659 N.W.2d 210
    , 215 (Iowa 2003); cf. La Due v. G & A Grp. Inc., 
    660 N.Y.S.2d 215
    ,
    216 (App. Div. 1997) (declining to grant summary judgment based on the
    storm-in-progress rule because while it was undisputed some snowfall
    occurred “on the date of plaintiff’s accident, the meteorological records do
    not demonstrate the specific hours during which the snow fell”).
    Furthermore, the Davenport data reflects 0.01 inches of precipitation on
    January 25. Thus, the trace amounts on January 21 totaled even less
    than that. I would conclude as a matter of law that precipitation totaling
    less than 0.01 inches on January 21 did not impede Marriott’s efforts to
    clear the ice from the sidewalk.
    Indeed, the fact that Marriott claims to have made repeated efforts
    to clear ice and snow after all accumulation associated with the storm
    event stopped is compelling evidence that the weather in the early
    morning hours of January 21 posed no obstacle making removal of ice
    from Marriott’s sidewalk impractical.    This is not a case where a land
    occupier tried once in vain to clear a path but howling winds and
    relentless snowfall forced them inside to await the storm’s passage, or a
    case where “[a] fairly warm autumn day . . . suddenly changed into a
    freezing winter’s evening by an outburst of elemental fury.” Parks v. City
    of Des Moines, 
    195 Iowa 972
    , 983, 
    191 N.W. 728
    , 733 (1923) (De Graff,
    J., dissenting). Rather, Marriott’s employees attempted to clear—or at
    least represented that they did clear—the sidewalks at least six times
    between 6:00 p.m. on January 20 and 6:00 a.m. on January 21.
    45
    Nor did the lay testimony about the weather conditions on
    January 21 constitute substantial evidence supporting a continuing-
    storm instruction. Like the district court, I would conclude the majority
    of statements—for example, that “it was quite icy” and “there were
    accidents all over town”—simply described the effects of the January 20
    storm event, not its continuation at a time material to Alcala’s fall. At
    best, one or two witnesses testified that there was mist in the air on the
    morning of January 21. But I find no substantial evidence in this record
    tending to prove the weather was so inclement as to make it impractical
    to clear Marriott’s sidewalk of ice before Alcala fell. Accordingly, I find no
    error in the district court’s refusal to give the continuing-storm
    instruction Marriott requested.
    Finding no error in the instructions given by the district court, I
    would vacate the decision of the court of appeals and affirm the district
    court judgment in Alcala’s favor.
    Wiggins and Appel, JJ., join this concurrence in part and dissent
    in part.
