Scott County within Iowa. 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.

The NCEI record lists 1,273 events for Scott County, Iowa, between 1950 and 2026; damaging wind account for the largest share.

That is 277.9 events per 100 square miles, above the Iowa figure of 124.6, and 73.1 per 10,000 residents against 218.0 statewide.

52 events fall in the 12 months to 30 Jun 2026. NCEI attributes 1 death and 65 injuries to events in the county, with property damage estimated at $52M and crop damage at $30M.

FEMA has designated the county in 20 federal disaster declarations since 1953; the most recent is Severe Storms, Flooding, Straight-Line Winds, And Tornadoes (major disaster, 24 Jun 2024).

National Flood Insurance Program policyholders in the county filed 2,267 claims since 1978, of which 1,853 were paid, totalling $35M (about $19K per paid claim). FEMA counts 553 residential flood policies in force.

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

Trend: 783 events in the 20 years to 2025 against 391 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.
