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 529 storm events in Ottawa County, Michigan, led by damaging wind.

That is 93.9 events per 100 square miles, above the Michigan figure of 64.2, and 17.7 per 10,000 residents against 36.1 statewide.

27 events fall in the 12 months to 30 Jun 2026. NCEI attributes 21 deaths and 258 injuries to events in the county, with property damage estimated at $121M and crop damage at $12M.

FEMA has designated the county in 16 federal disaster declarations since 1953; the most recent is Covid-19 Pandemic (major disaster, 27 Mar 2020).

National Flood Insurance Program policyholders in the county filed 336 claims since 1978, of which 232 were paid, totalling $3.4M (about $14K per paid claim). FEMA counts 318 residential flood policies in force.

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

Trend: 212 events in the 20 years to 2025 against 229 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.
