Cullman 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 1 Oct 2026; NFIP claims as of 8 Sep 2026.

Between 1950 and 2026, NCEI recorded 1,339 storm events in Cullman County, Alabama, led by damaging wind.

That is 182.2 events per 100 square miles, above the Alabama figure of 87.3, and 149.6 per 10,000 residents against 87.8 statewide.

56 events fall in the 12 months to 30 Jun 2026. NCEI attributes 17 deaths and 310 injuries to events in the county, with property damage estimated at $109M and crop damage at $1.2M.

FEMA has designated the county in 32 federal disaster declarations since 1953; the most recent is Hurricane Helene (emergency, 26 Sep 2024).

National Flood Insurance Program policyholders in the county filed 30 claims since 1978, of which 23 were paid, totalling $564K (about $25K per paid claim). FEMA counts 77 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 Low" ($35M a year across 18 hazards).

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

Trend: 882 events in the 20 years to 2025 against 321 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.
