Leon County within Florida. Dots: HailTornadoFloodWind event locations in the kept record. Boundaries: US Census Bureau.

NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.

The NCEI record lists 1,350 events for Leon County, Florida, between 1950 and 2026; damaging wind account for the largest share.

That is 202.0 events per 100 square miles, above the Florida figure of 73.8, and 46.1 per 10,000 residents against 18.2 statewide.

46 events fall in the 12 months to 30 Jun 2026. NCEI attributes 14 deaths and 12 injuries to events in the county, with property damage estimated at $438M and crop damage at $51M.

FEMA has designated the county in 36 federal disaster declarations since 1953; the most recent is Hurricane Helene (major disaster, 28 Sep 2024).

National Flood Insurance Program policyholders in the county filed 1,015 claims since 1978, of which 749 were paid, totalling $12M (about $16K per paid claim). FEMA counts 2,487 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Moderate" and its expected annual loss as "Relatively Moderate" ($143M a year across 18 hazards).

97 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 10 of them within 50 miles at hurricane strength.

Recorded events in Leon County by decade and hazard group. HailTornadoFloodWindWinterTropicalHeatColdDroughtLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 1,091 events in the 20 years to 2025 against 159 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
