Kane County within Illinois. 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 29 Sep 2026; NFIP claims as of 8 Sep 2026.

Between 1950 and 2026, NCEI recorded 1,147 storm events in Kane County, Illinois, led by damaging wind.

That is 220.8 events per 100 square miles, above the Illinois figure of 120.2, and 22.2 per 10,000 residents against 52.7 statewide.

109 events fall in the 12 months to 30 Jun 2026. NCEI attributes 5 deaths and 29 injuries to events in the county, with property damage estimated at $33M.

FEMA has designated the county in 16 federal disaster declarations since 1953; the most recent is Covid-19 Pandemic (major disaster, 26 Mar 2020).

National Flood Insurance Program policyholders in the county filed 929 claims since 1978, of which 720 were paid, totalling $12M (about $16K per paid claim). FEMA counts 634 residential flood policies in force.

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

Trend: 826 events in the 20 years to 2025 against 191 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.
