Tornado Risk in Crook County, WY
Crook County's tornado history, by the numbers
39 tornado tracks have crossed Crook County since 1958 by NOAA's count, roughly one every 1.9 years - the Elevated band on this site's scale. That is the 79th percentile nationally for tornado frequency. Within Wyoming alone, Crook County ranks 7 of 23 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Crook County in NOAA's 76-year database. Of its 39 recorded tracks, 30 were weak (EF0-1) and 8 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 Crook County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in Wyoming often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Crook County's figure does not tell you
Crook County's figure is county-wide, not address-specific. Crook County covers about 2,854 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. Crook County has about 7,775 residents.
