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.
New York Attorney
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.
Satisfied Personal Injury Attorney
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.
Frequently Asked Questions
- What types of legal cases can benefit from forensic meteorology?
Forensic meteorology is valuable in a wide range of cases, including premises liability (slip and fall accidents), property damage from hurricanes, hail, or flooding, wrongful death involving lightning or severe weather, insurance claim disputes, and weather-related vehicle accidents. If weather played any role in an incident, a forensic meteorologist can provide scientific evidence to support or refute claims.
- How does John Bryant reconstruct past weather conditions?
John uses a combination of historical weather databases, NEXRAD Doppler radar data (including Level II Dual-Pol analysis), surface observation records, and advanced meteorological modeling. This multi-source approach allows him to pinpoint exact conditions, such as precipitation onset, wind speeds, or lightning activity, at a specific location and time, producing court-admissible findings grounded in the scientific method.
- Does John Bryant work for both plaintiffs and defendants?
Yes. John maintains a balanced practice, providing objective, independent analysis for both plaintiff and defense counsel. His testimony is always rooted in science, not advocacy, which makes his findings more credible and resilient under Daubert standards in federal and state courts
- What does the process look like from initial consultation to testimony?
After an initial consultation to review the details of your case, John gathers and analyzes all relevant meteorological data for the incident’s location, date, and time. He then prepares a comprehensive forensic weather report suitable for legal proceedings. If needed, he is available to provide deposition testimony and appear in court as a qualified expert witness to translate complex atmospheric data into clear, compelling narratives for judges and juries.
