Chippewa County within Wisconsin. 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 581 storm events in Chippewa County, Wisconsin, led by damaging wind.

That is 57.6 events per 100 square miles, below the Wisconsin figure of 85.6, and 86.9 per 10,000 residents against 78.6 statewide.

18 events fall in the 12 months to 30 Jun 2026. NCEI attributes 8 deaths and 119 injuries to events in the county, with property damage estimated at $46M and crop damage at $250K.

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

Trend: 282 events in the 20 years to 2025 against 181 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.
