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

Trend: 39 events in the 20 years to 2025 against 9 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.
