Johnson County within Indiana. 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.

The NCEI record lists 514 events for Johnson County, Indiana, between 1950 and 2026; damaging wind account for the largest share.

That is 160.4 events per 100 square miles, above the Indiana figure of 120.7, and 31.3 per 10,000 residents against 63.5 statewide.

17 events fall in the 12 months to 30 Jun 2026. NCEI attributes 5 deaths and 39 injuries to events in the county, with property damage estimated at $165M and crop damage at $90M.

FEMA has designated the county in 16 federal disaster declarations since 1953; the most recent is Severe Winter Storm (emergency, 24 Jan 2026).

Trend: 281 events in the 20 years to 2025 against 184 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.
