Lancaster County within South Carolina. 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 557 events for Lancaster County, South Carolina, between 1950 and 2026; damaging wind account for the largest share.

That is 101.4 events per 100 square miles, in line with the South Carolina figure of 108.7, and 55.5 per 10,000 residents against 62.9 statewide.

7 events fall in the 12 months to 30 Jun 2026. NCEI attributes 4 deaths and 28 injuries to events in the county, with property damage estimated at $32M and crop damage at $195K.

FEMA has designated the county in 24 federal disaster declarations since 1953; the most recent is Severe Winter Storm (emergency, 23 Jan 2026).

National Flood Insurance Program policyholders in the county filed 34 claims since 1978, of which 23 were paid, totalling $514K (about $22K per paid claim). FEMA counts 155 residential flood policies in force.

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

Trend: 412 events in the 20 years to 2025 against 118 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.
