How Likely Is a Tornado in Campbell County, WY?
Campbell County, WY: what NOAA's tornado record says
Campbell County has recorded 95 tornado touches in NOAA's 76-year database, a rate of roughly one every 0.8 years - our High band. Put another way: Campbell County sees more tornado activity than 98% of US counties. Among 23 Wyoming counties in this dataset, Campbell County ranks 2 for how often a tornado touches down.
Beyond the frequency band: violent history
84 weak and 11 significant tornadoes make up Campbell County's 95-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Campbell County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Wyoming 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 Wyoming this pass.
What a direct hit isn't required for
The storm that misses Campbell County outright can still take its power out - outbreak-scale outages across Wyoming are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What this number is, and is not
One caveat before relying on Campbell County's number: it is county-wide, and it covers about 4,802 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. Campbell County has about 47,946 residents.
