Forensic meteorology is the application of atmospheric science to
legal cases, criminal investigations, and insurance claims to help
determine the root causes of incidents and accidents in which
weather may have been a contributing factor. Meteorology is an
interdisciplinary science atthe intersection of physics and chemistry
involving the dynamics of the atmosphere from the surface of the earth to the near-space environment. The ability to conduct an effective meteorological forensic investigation requires a technical expert with substantial education, training and experience.

Meteorological forensic investigations involve authoritative assessment of the past occurrence and effects of weather-related phenomena including snow, ice, freezing conditions, frost, dew, lightning, rain, flooding, hail, reduced visibilities, high winds, drought, flooding, heat waves, fog, storm surge, smoke, severe storms, hurricanes and tornadoes. WeatherSleuth's rigorous process was developed through many years of experience in scientific research and investigative problem solving.

Do you need important weather information to justify a legal case or validate an insurance claim? WeatherSleuth's professional forensic meteorologists can assist investigators, attorneys and claims adjustors by obtaining, analyzing and interpreting appropriate historical weather data. If necessary, WeatherSleuth will conduct a site survey at the location of the loss, injury or other incident as part of the investigation. Throughout an investigation, a WeatherSleuth expert will be available to provide verbal briefings and other, informal updates. Following research and analysis, we will generate a formal, site-specific written report. A Certified Consulting Meteorologist (CCM) from WeatherSleuth LLC can provide depositions as well as credible, expert testimony in support of litigation.
