About Tornadoes in Seminole

This overview was written August 10, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.

Seminole, Florida, can pass through long quiet stretches — whole seasons when severe weather amounts to routine sea-breeze thunderstorms — and then face a day when tornadoes cross the Pinellas peninsula in earnest. That contrast is built into the local climate. Wedged between the Gulf of Mexico and Tampa Bay, the city sits in deeply humid air for much of the year; summer sea-breeze collisions can spin up brief funnels and waterspouts that come ashore, while cool-season fronts, aided by a strong subtropical jet stream in El Niño winters, occasionally drive organized supercells across the county. The NOAA Storm Prediction Center maintains the event history from which this page's listings are drawn.

That history now spans generations of residents. Grandparents may remember April 4, 1966, when a long-track F4 crossed the peninsula, killing 11 people, injuring 530, and carving a path 135.8 miles long; an F4 had already struck on April 15, 1958, injuring 7. Their children saw an F3 kill 3 people and injure 94 on May 4, 1978, and on October 3, 1992 another F3 killed 3 people and injured 75. The current generation has its own markers: an EF2 tracked 13.11 miles through the area on December 16, 2020, and a brief EF0 touched down on September 25, 2025.
