Washington 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.

The NCEI record lists 405 events for Washington County, Tennessee, between 1950 and 2026; damaging wind account for the largest share.

That is 124.0 events per 100 square miles, in line with the Tennessee figure of 112.2, and 30.2 per 10,000 residents against 66.4 statewide.

14 events fall in the 12 months to 30 Jun 2026. NCEI attributes 9 deaths and 2 injuries to events in the county, with property damage estimated at $51M and crop damage at $287K.

FEMA has designated the county in 16 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 152 claims since 1978, of which 124 were paid, totalling $6.1M (about $49K per paid claim). FEMA counts 204 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Low" and its expected annual loss as "Relatively Low" ($23M a year across 18 hazards).

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

Trend: 253 events in the 20 years to 2025 against 134 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.
