Wisconsin, 2026
The year's recorded storm events, federal disaster declarations and flood insurance claims. 2026 is partial: storm records run through 30 Jun 2026.
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.
