Tornado Risk in Weston County, WY
How likely is a tornado in Weston County, WY?
26 tornado tracks have crossed Weston County since 1950 by NOAA's count, roughly one every 2.9 years - the Elevated band on this site's scale. That is the 61st percentile nationally for tornado frequency. Wyoming has 23 counties in this dataset; Weston County ranks 12 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Weston County in NOAA's 76-year database. Of its 26 recorded tracks, 23 were weak (EF0-1) and 3 significant (EF2-3).
Shelter and safe-room economics
Wyoming does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Weston County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
A direct hit is not required for Weston County to lose power - outbreak-wide outages across Wyoming 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 Weston County's figure does not tell you
Weston County's figure is county-wide, not address-specific. Weston County covers about 2,398 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Weston County has about 6,866 residents.
