Tornado Risk in Worth County, MO
Worth County, MO: what NOAA's tornado record says
12 tornado tracks have crossed Worth County since 1955 by NOAA's count, roughly one every 6.3 years - the Low band on this site's scale. That is the 33rd percentile nationally for tornado frequency. Missouri has 115 counties in this dataset; Worth County ranks 102 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Worth County in NOAA's 76-year database. Of its 12 recorded tracks, 10 were weak (EF0-1) and 2 significant (EF2-3).
Shelter and safe-room economics
Missouri does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Worth County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
1,872 people live in Worth County, and a tornado outbreak's power loss usually reaches far more of Missouri than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Worth County's figure does not tell you
Worth County's figure is county-wide, not address-specific. Worth County covers about 267 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. Worth County has about 1,872 residents.
