Lawrence 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.

The NCEI record lists 714 events for Lawrence County, Pennsylvania, between 1950 and 2026; damaging wind account for the largest share.

That is 199.8 events per 100 square miles, above the Pennsylvania figure of 121.6, and 83.5 per 10,000 residents against 42.0 statewide.

33 events fall in the 12 months to 30 Jun 2026. NCEI attributes 0 deaths and 16 injuries to events in the county, with property damage estimated at $10M and crop damage at $16K.

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

Trend: 461 events in the 20 years to 2025 against 201 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.
