How Likely Is a Tornado in Duchesne County, UT?
How likely is a tornado in Duchesne County, UT?
Duchesne County has recorded 5 tornado touches in NOAA's 76-year database, a rate of roughly one every 15.2 years - our Minimal band. Put another way: Duchesne County sees more tornado activity than 16% of US counties. Among 29 Utah counties in this dataset, Duchesne County ranks 14 for how often a tornado touches down.
Beyond the frequency band: violent history
3 weak and 2 significant tornadoes make up Duchesne County's 5-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Duchesne County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Utah 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 Utah this pass.
What a direct hit isn't required for
20,803 people live in Duchesne County, and a tornado outbreak's power loss usually reaches far more of Utah than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What this number is, and is not
One caveat before relying on Duchesne County's number: it is county-wide, and it covers about 3,236 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. Duchesne County has about 20,803 residents.
