How Likely Is a Tornado in Davis County, UT?
Davis County, UT: what NOAA's tornado record says
Davis County has recorded 12 tornado touches in NOAA's 76-year database, a rate of roughly one every 6.3 years - our Low band. Put another way: Davis County sees more tornado activity than 35% of US counties. Among 29 Utah counties in this dataset, Davis County ranks 2 for how often a tornado touches down.
Beyond the frequency band: violent history
11 weak and 1 significant tornadoes make up Davis County's 12-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Davis 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
A direct hit is not required for Davis County to lose power - outbreak-wide outages across Utah regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What this number is, and is not
One caveat before relying on Davis County's number: it is county-wide, and it covers about 325 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. Davis County has about 378,470 residents.
