The Value of Past Forecasts in Forensic Studies and Forensic Reports

 Contributed by Patti Robertson, CompuWeather Forensic Order Specialist and Account Executive

You’re probably aware that our forensic meteorologists can document any type of weather condition on land or sea in nearly every location in the world. Did you know that we can also tell you what the weather forecast was for any location and any date?  The forecast often becomes an issue when, for example, a contractor leaves a job site at the end of the day after tarping the roof. During the night the wind rips off the tarp and heavy rain enters the building. All of a sudden you have a claim for thousands of dollars of water damage.  The questions that arise are:  Should the contractor have known that storms and high winds were expected overnight? Was this a sudden, unexpected event with no warning?  What would a reasonable person be expected to know about what was forecasted?

Forecasts and advisories are also useful for determining what level of wind speed might have occurred in a particular area.  When the National Weather Service issues a high wind warning, it means that wind speeds of a certain range are expected in that area. Therefore, even if the nearby reporting stations did not record high winds, we can often conclude that high winds likely occurred.

The only forecasts accepted by courts in the US are those issued by the National Weather Service, and they can be certified just like weather data. CompuWeather provides a reliable source for forecast information and the fulfillment of certified NWS data.
