How likely is a tornado in Glenn County, CA?

Glenn County has recorded 11 tornado touches in NOAA's 76-year database, a rate of roughly one every 6.9 years - our Low band. Put another way: Glenn County sees more tornado activity than 32% of US counties. California has 58 counties in this dataset; Glenn County ranks 17 of them by frequency.

Beyond the frequency band: violent history

10 weak and 1 significant tornadoes make up Glenn County's 11-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.

The dollar figure Glenn County's rating leads to

Cost nationally: $2,890-$13,280, about $7,645 typical. California has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for California this pass.

What a direct hit isn't required for

Tornado outbreaks routinely knock out power across California for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.

What this number is, and is not

One caveat before relying on Glenn County's number: it is county-wide, and it covers about 1,314 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Glenn County has about 28,304 residents.
