Chatham County within Georgia. 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.

Chatham County, Georgia, has 990 weather events in the NCEI Storm Events record since 1950, most of them damaging wind.

That is 228.6 events per 100 square miles, above the Georgia figure of 98.3, and 33.4 per 10,000 residents against 52.5 statewide.

51 events fall in the 12 months to 30 Jun 2026. NCEI attributes 4 deaths and 62 injuries to events in the county, with property damage estimated at $25M and crop damage at $1K.

FEMA has designated the county in 19 federal disaster declarations since 1953; the most recent is Hurricane Helene (major disaster, 30 Sep 2024).

National Flood Insurance Program policyholders in the county filed 5,467 claims since 1978, of which 3,958 were paid, totalling $82M (about $21K per paid claim). FEMA counts 19,764 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively High" and its expected annual loss as "Relatively High" ($277M a year across 18 hazards).

122 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 18 of them within 50 miles at hurricane strength.

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

Trend: 728 events in the 20 years to 2025 against 173 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.
