County storm and disaster record · FIPS 06095 · population 452,833 · 822 sq mi

NOAA's Storm Events Database holds 388 records for Solano County, California from 1950 through June 30, 2026, on 254 days; the most frequent are high wind and dust records (100 records). 336 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day.

FEMA has issued 30 declarations naming the county since 1964, 28 of them for natural hazards; the latest for a natural hazard was “Severe Winter Storms, Straight-Line Winds, Flooding, Landslides, and Mudslides” on April 3, 2023.
