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

Trend: 137 events in the 20 years to 2025 against 134 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.
