Thunderstorms are a frequent occurrence in Florida. In fact Florida leads the nation in number of thunderstorms, averaging over 70 thunderstorm days per year. Hazards within thunderstorms include lightning, hail, gusty winds, heavy rain that may cause flooding, and tornadoes.

The Storm Prediction Center issues Convective Outlooks depicting the severe thunderstorm/tornado risk for each day and issues Severe Thunderstorm or Tornado Watches if conditions are favorable for severe weather. The National Weather Service issues a Severe Thunderstorm Warning when a thunderstorm produces hail the size of a U.S. quarter (1”) or larger or winds of 58 mph or stronger.

Did you know? Thunderstorms are common in the interior areas of Florida. One reason is that the west coast and east coast sea breeze fronts can converge in the middle of the state, leading to the development of storms. Florida is the only state where two sea breezes can collide.
