Weather Facts
TORNADO FACTS - Florida has two Tornado Seasons. The Summer Season, from June until September has the highest frequencies with usual intensities of F0 or F1 on the Fujita Scale. This includes those tornadoes that form from landfalling Tropical Cyclones. The Deadly Spring Season, from February through April is characterized by more powerful tornadoes because of the presence of the jet stream. When the jet stream digs south into Florida and is accompanied by a strong cold front and a strong squall line of thunderstorms, the jet stream's high level winds of 100 to 200 mph often strengthen a thunderstorm into what meteorologists call a supercell or mesocyclone. These powerful storms can move at speeds of 30 to 50 mph, produce dangerous downburst winds, large hail and the most deadly tornadoes.
