Jefferson County within Alabama. 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 29 Sep 2026; NFIP claims as of 8 Sep 2026.

The NCEI record lists 1,814 events for Jefferson County, Alabama, between 1950 and 2026; damaging wind account for the largest share.

That is 163.2 events per 100 square miles, above the Alabama figure of 87.3, and 27.2 per 10,000 residents against 87.8 statewide.

53 events fall in the 12 months to 30 Jun 2026. NCEI attributes 127 deaths and 1,746 injuries to events in the county, with property damage estimated at $2.0B and crop damage at $3.4M.

FEMA has designated the county in 39 federal disaster declarations since 1953; the most recent is Hurricane Helene (emergency, 26 Sep 2024).

National Flood Insurance Program policyholders in the county filed 2,884 claims since 1978, of which 2,279 were paid, totalling $47M (about $21K per paid claim). FEMA counts 1,129 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively High" and its expected annual loss as "Relatively High" ($262M a year across 18 hazards).

23 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 0 of them within 50 miles at hurricane strength.

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

Trend: 871 events in the 20 years to 2025 against 590 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.
