Tornado Risk in Cape Girardeau County, MO
Cape Girardeau County, MO: what NOAA's tornado record says
49 tornado tracks have crossed Cape Girardeau County since 1952 by NOAA's count, roughly one every 1.6 years - the High band on this site's scale. That is the 87th percentile nationally for tornado frequency. Within Missouri alone, Cape Girardeau County ranks 4 of 115 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Cape Girardeau County in NOAA's 76-year database. Of its 49 recorded tracks, 35 were weak (EF0-1) and 14 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 Cape Girardeau 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 Cape Girardeau County to lose power - outbreak-wide outages across Missouri 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 Cape Girardeau County's figure does not tell you
Cape Girardeau County's figure is county-wide, not address-specific. Cape Girardeau County covers about 579 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. Cape Girardeau County has about 83,658 residents.
