Snow and Ice Expert Witness for Slip and Fall Cases
Snow and ice slip and fall cases often depend on understanding what the weather was doing before and at the time of an incident. I analyze historical weather conditions to determine whether snow, freezing rain, sleet, freezing temperatures, melting, or refreezing may have contributed to hazardous surface conditions.
The analysis can help establish when precipitation began and ended, whether temperatures were below freezing, whether a freeze and thaw cycle occurred, and whether conditions were favorable for snowmelt or ice formation. I compare the reported incident timeline and location with available meteorological evidence to provide attorneys, insurance carriers, and other parties with a clear reconstruction of the relevant weather conditions.

Personal Injury/Weather-Related Vehicular Accident Case
After a harrowing experience of being involved in a motor vehicle accident during a severe winter storm last year, I found myself in an unexpected and challenging situation. The storm brought not just snow but also lots of ice and freezing rain. After the accident, as I stepped out of my car, I slipped on the ice, adding to the complexity of my case. I was initially at a standstill with my insurance company. They disputed the claims about the weather conditions, specifically at the time of the accident. This is when I turned to the expertise of John Bryant. His analysis and reconstruction of the precise weather conditions at the time and location of my accident were remarkable. John’s report detailed the specific weather conditions, including the exact type of precipitation, temperature, and ice conditions at the time and my location. This level of detail was crucial. It was his expert testimony and report that made all the difference. Thanks to his analysis, I was able to settle the dispute with my insurance company quickly after they received his report. I am deeply grateful for John Bryant’s professionalism and expertise. His work not only provided clarity and evidence in my case but also showcased his commitment to applying expert weather knowledge to help people in need when facing challenges like mine. This experience left me with such a respect for forensic meteorology and its significant role in our lives, especially in critical times of need.

Slip-and-Fall Case
I recently worked with John Bryant of Weather and Climate Consulting, LLC, on a New York slip-and-fall matter in which the ‘Storm in Progress’ defense was the central issue. John’s analysis of NEXRAD radar and site-specific temperature trends was surgical. He pinpointed the exact minute precipitation ceased and tracked the freeze/thaw cycle with a level of precision I haven’t seen from larger national firms. His work provided the objective evidence we needed to establish the timing of the hazard. He is easy to work with, highly responsive, and very cost-effective. If you have a case where the “when” and “how” of ice formation are in question, he is your guy.

Flash Flood Case
John’s Forensic Meteorology expertise was invaluable to a Flash Flood case. When a tragic flash flooding incident occurred in an isolated area, the closest weather reports did not reflect the true conditions at the site. There was not a certified storm report to be found. This posed a serious challenge. However, through his meticulous analysis and reconstruction of the weather patterns, John was able to demonstrate precisely what conditions were like when an individual encountered flood waters that unfortunately led to a loss of life. Despite what the broad regional data showed, he proved beyond a doubt that intense rainfall did occur in that location on that day and weather conditions played a part. John has an uncanny ability to dissect complex weather events and present the findings in a clear, easy to understand manner. His customized report helped bring a bit of justice to such a tragic incident. I would highly recommend retaining John for any legal matter involving the reconstruction of past weather or climate conditions. His skills and precision give attorneys and insurance companies the meteorological facts they need to effectively argue critical cases.

FAQs
- What is a snow and ice expert witness?
A snow and ice expert witness uses meteorological evidence to reconstruct weather conditions related to an incident. The analysis may address snowfall, freezing temperatures, freezing rain, precipitation timing, melting, refreezing, and other factors relevant to possible snow or ice formation.
- Can a forensic meteorologist determine whether black ice was possible?
Meteorological records can show whether temperatures, precipitation, melting, refreezing, and other conditions were favorable for black ice formation. The conclusion depends on the quality of the available weather and case evidence.
- Can historical weather data show when ice formed?
Historical data can help identify periods when conditions were favorable for ice formation. Temperature trends, previous precipitation, snowmelt, freezing rain, and freeze and thaw cycles may help narrow the likely timing, although weather data alone may not establish the exact moment ice formed on a particular surface.
- How do you determine weather conditions at the accident location?
I evaluate observations from relevant weather stations along with radar data, precipitation records, temperature trends, and other available meteorological evidence. The relationship between each source and the incident location is considered rather than relying solely on the nearest weather station.
- What weather records are useful in a snow and ice slip and fall investigation?
Useful evidence can include temperature and precipitation observations, snowfall and snow depth records, radar data, visibility, dew point, wind, and historical weather reports. Photographs, surveillance footage, maintenance records, and witness accounts may also provide useful context.
- Can you determine whether a storm was still in progress?
Weather observations and radar data can often help establish when precipitation began, continued, and ended near an incident location. This can be important in cases where the timing of a winter weather event relative to the reported fall is disputed.
- How can freeze and thaw cycles contribute to a slip and fall?
Temperatures rising above freezing can allow snow or ice to melt. If temperatures later fall below freezing, that moisture may refreeze. Reviewing these temperature changes alongside precipitation and snow conditions can help evaluate whether refreezing was meteorologically possible.
- Can weather radar be used in a slip and fall case?
Yes. Radar can help establish the location, movement, timing, and intensity of precipitation. When combined with surface weather observations, it can provide a more detailed reconstruction of the weather affecting the incident area.
- What information should I provide for a case review?
The incident location, date, approximate time, description of the reported surface condition, and available case documents are useful starting points. Photographs, surveillance footage, witness statements, maintenance records, and snow removal records may also help guide the meteorological analysis.
- Do you work with both plaintiff and defense attorneys?
Yes. Meteorological analysis is based on the available weather evidence and the questions presented in the case. The objective is to provide a clear scientific reconstruction of the relevant conditions regardless of which party requests the analysis.
