The number that matters more than frequency

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 Lassen County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in California often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Lassen County's figure does not tell you
Lassen County's figure is county-wide, not address-specific. Lassen County covers about 4,541 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. Lassen County has about 28,340 residents.
