Snow and Ice Expert Witness for Slip and Fall Cases
Slip and fall cases often come down to one key question: was the hazard preventable, and were the conditions reasonably foreseeable at the time of the incident?
I analyze historical weather conditions to determine whether snow, ice, or freezing conditions were present at the location and time of the incident. This helps clarify whether environmental conditions may have contributed to unsafe surfaces and resulting injuries.
About This Service
This service supports legal teams, insurance carriers, and property stakeholders in evaluating slip and fall incidents where weather conditions may have contributed to unsafe walking surfaces.
The analysis focuses on confirming whether snow, ice, or freezing conditions were present and whether those conditions align with the reported incident timeline and location. The goal is to provide clear, data-backed insight to support liability discussions and case evaluation.

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.

Slip and Fall Case
I hired John Bryant as an expert witness for a slip and fall case involving intricate winter weather data. His exhaustive analysis to find scarce, precise data were instrumental in dismantling the opposition’s claims. The evidence he provided to reconstruct the weather event was critical to securing a favorable settlement for my client. If you need an expert weather witness whose detailed, authoritative reports can distinguish between winning and losing, John Bryant is the person to call.

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.
