American Meteorological Society Certification (AMS) Practice

The term "severe thunderstorm" specifically indicates a thunderstorm that is capable of producing damaging winds, large hail, or tornadoes. The classification focuses on the intensity and potential hazardous impacts of the storm rather than just its precipitation levels or the time of year it occurs.

This designation is crucial for public safety and emergency management, as it helps identify storms that pose a significant risk to life and property. Severe thunderstorms are characterized by wind gusts of 58 mph or greater, hail of one inch in diameter or larger, or the presence of tornadoes. Being aware of this definition helps individuals adequately prepare and respond to severe weather warnings.

Other descriptions, such as a thunderstorm that produces heavy rain or one that is simply weak and insignificant, do not capture the potential dangers associated with severe thunderstorms. Additionally, the occurrence of thunderstorms during a specific season does not inherently classify them as severe unless they meet the established criteria for severe weather.
