Greene County within Pennsylvania. 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.

Greene County, Pennsylvania, has 465 weather events in the NCEI Storm Events record since 1950, most of them damaging wind.

That is 80.7 events per 100 square miles, below the Pennsylvania figure of 121.6, and 131.5 per 10,000 residents against 42.0 statewide.

19 events fall in the 12 months to 30 Jun 2026. NCEI attributes 1 death and 3 injuries to events in the county, with property damage estimated at $13M and crop damage at $16K.

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

Trend: 280 events in the 20 years to 2025 against 147 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.
