Tornado Risk in Marion County, KY
Marion County, KY: what NOAA's tornado record says
12 tornado tracks have crossed Marion County since 1973 by NOAA's count, roughly one every 6.3 years - the Low band on this site's scale. That is the 34th percentile nationally for tornado frequency. Kentucky has 120 counties in this dataset; Marion County ranks 47 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Marion 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
Kentucky does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Marion County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
19,851 people live in Marion County, and a tornado outbreak's power loss usually reaches far more of Kentucky than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Marion County's figure does not tell you
Marion County's figure is county-wide, not address-specific. Marion County covers about 344 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. Marion County has about 19,851 residents.
