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 320 events for Lake County, Tennessee, between 1950 and 2026; heat account for the largest share.

That is 193.0 events per 100 square miles, above the Tennessee figure of 112.2, and 448.9 per 10,000 residents against 66.4 statewide.

35 events fall in the 12 months to 30 Jun 2026. NCEI attributes 3 deaths and 1 injury to events in the county, with property damage estimated at $9.1M and crop damage at $57K.

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

Trend: 229 events in the 20 years to 2025 against 70 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.
