How Likely Is a Tornado in Cowlitz County, WA?
Cowlitz County, WA: what NOAA's tornado record says
Cowlitz County has recorded 3 tornado touches in NOAA's 76-year database, a rate of roughly one every 25.6 years - our Minimal band. Put another way: Cowlitz County sees more tornado activity than 12% of US counties. Among 39 Washington counties in this dataset, Cowlitz County ranks 14 for how often a tornado touches down.
Beyond the frequency band: violent history
3 weak and 0 significant tornadoes make up Cowlitz County's 3-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Cowlitz County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Washington 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 Washington this pass.
What a direct hit isn't required for
Tornado outbreaks routinely knock out power across Washington 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 Cowlitz County's number: it is county-wide, and it covers about 1,141 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. Cowlitz County has about 113,982 residents.
