Chatham County within North 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.

Between 1950 and 2026, NCEI recorded 548 storm events in Chatham County, North Carolina, led by damaging wind.

That is 80.4 events per 100 square miles, below the North Carolina figure of 112.5, and 70.4 per 10,000 residents against 51.8 statewide.

37 events fall in the 12 months to 30 Jun 2026. NCEI attributes 4 deaths and 5 injuries to events in the county, with property damage estimated at $13M and crop damage at $20M.

FEMA has designated the county in 22 federal disaster declarations since 1953; the most recent is Severe Winter Storm (emergency, 24 Jan 2026).

National Flood Insurance Program policyholders in the county filed 41 claims since 1978, of which 35 were paid, totalling $2.1M (about $61K per paid claim). FEMA counts 211 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" ($25M a year across 18 hazards).

68 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 2 of them within 50 miles at hurricane strength.

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

Trend: 366 events in the 20 years to 2025 against 148 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.
