NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 29 Sep 2026; NFIP claims as of 8 Sep 2026.

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

Trend: 202 events in the 20 years to 2025 against 122 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.
