What is Storm Data? Storm Data is a monthly publication that details any unusual or significant weather events that were reported to the National Weather Service. It includes (but isn't limited to winter weather, severe thunderstorms, tornadoes, floods, and high wind.) All fatalities and injuries that are directly related to weather are included, as well as any weather that caused significant damage.
My roof was blown off in a thunderstorm. Why isn't that storm in the report? We probably did not receive the report. We will research storms (both during and after the event) through local newspapers, law enforcement, and spotters. If the event was not reported to any of these organizations and you didn't report it to us directly, we probably didn't get it.
How long after an event is Storm Data available? At the end of each month, all of the events from the month are entered into a database. All of the reports are verified. Newspaper clippings are scoured for additional reports and clarification of known events. Then a final summary of each Weather Episode during the month is compiled. This process usually takes 1 to 2 months, depending on the weather during that season.
