Tornado Risk in Madison County, OH
Madison County's tornado history, by the numbers
16 tornado tracks have crossed Madison County since 1965 by NOAA's count, roughly one every 4.7 years - the Moderate band on this site's scale. That is the 43rd percentile nationally for tornado frequency. Within Ohio alone, Madison County ranks 48 of 88 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Madison County in NOAA's 76-year database. Of its 16 recorded tracks, 12 were weak (EF0-1) and 4 significant (EF2-3).
Shelter and safe-room economics
Ohio does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Madison 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 Madison County to lose power - outbreak-wide outages across Ohio 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 Madison County's figure does not tell you
Madison County's figure is county-wide, not address-specific. Madison County covers about 467 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. Madison County has about 45,531 residents.
