Tornado Risk in Solano County, CA
Solano County, CA: what NOAA's tornado record says
4 tornado tracks have crossed Solano County since 1989 by NOAA's count, roughly one every 18.9 years - the Minimal band on this site's scale. That is the 15th percentile nationally for tornado frequency. Within California alone, Solano County ranks 31 of 58 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Solano County in NOAA's 76-year database. Of its 4 recorded tracks, 4 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
California does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Solano County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
The storm that misses Solano County outright can still take its power out - outbreak-scale outages across California are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Solano County's figure does not tell you
Solano County's figure is county-wide, not address-specific. Solano County covers about 822 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Solano County has about 455,101 residents.
