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.

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

Trend: 312 events in the 20 years to 2025 against 107 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.
