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 422 storm events in Marion County, Tennessee, led by damaging wind.

That is 84.7 events per 100 square miles, below the Tennessee figure of 112.2, and 146.1 per 10,000 residents against 66.4 statewide.

7 events fall in the 12 months to 30 Jun 2026. NCEI attributes 6 deaths and 25 injuries to events in the county, with property damage estimated at $32M and crop damage at $198K.

FEMA has designated the county in 25 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 117 claims since 1978, of which 86 were paid, totalling $1.2M (about $14K per paid claim). FEMA counts 91 residential flood policies in force.

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

Trend: 249 events in the 20 years to 2025 against 153 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.
