Union 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.

Union County, North Carolina, has 630 weather events in the NCEI Storm Events record since 1950, most of them damaging wind.

That is 99.6 events per 100 square miles, in line with the North Carolina figure of 112.5, and 25.9 per 10,000 residents against 51.8 statewide.

10 events fall in the 12 months to 30 Jun 2026. NCEI attributes 4 deaths and 32 injuries to events in the county, with property damage estimated at $46M and crop damage at $505K.

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

Trend: 309 events in the 20 years to 2025 against 281 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.
