NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.

Recorded events in St. Helena Parish by decade and hazard group. HailTornadoFloodWindWinterTropicalHeatColdDroughtOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 94 events in the 20 years to 2025 against 66 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.
