Windham County within Vermont. 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 404 events for Windham County, Vermont, between 1950 and 2026; damaging wind account for the largest share.

That is 51.4 events per 100 square miles, below the Vermont figure of 119.4, and 87.7 per 10,000 residents against 170.5 statewide.

7 events fall in the 12 months to 30 Jun 2026. NCEI attributes 1 death and 8 injuries to events in the county, with property damage estimated at $11M.

FEMA has designated the county in 24 federal disaster declarations since 1953; the most recent is Tropical Depression Debby (emergency, 8 Aug 2024).

National Flood Insurance Program policyholders in the county filed 312 claims since 1978, of which 223 were paid, totalling $11M (about $49K per paid claim). FEMA counts 269 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Low" and its expected annual loss as "Relatively Low" ($20M a year across 18 hazards).

36 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 0 of them within 50 miles at hurricane strength.

Trend: 247 events in the 20 years to 2025 against 139 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.
