Carroll County within Tennessee. 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 536 storm events in Carroll County, Tennessee, led by damaging wind.

That is 89.7 events per 100 square miles, below the Tennessee figure of 112.2, and 188.5 per 10,000 residents against 66.4 statewide.

36 events fall in the 12 months to 30 Jun 2026. NCEI attributes 16 deaths and 200 injuries to events in the county, with property damage estimated at $27M.

FEMA has designated the county in 24 federal disaster declarations since 1953; the most recent is Severe Winter Storm (major disaster, 6 Feb 2026).

National Flood Insurance Program policyholders in the county filed 19 claims since 1978, of which 16 were paid, totalling $521K (about $33K per paid claim). FEMA counts 8 residential flood policies in force.

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

Trend: 365 events in the 20 years to 2025 against 117 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.
