Tornado Risk in Benton County, MO
Benton County, MO: what NOAA's tornado record says
29 tornado tracks have crossed Benton County since 1954 by NOAA's count, roughly one every 2.6 years - the Elevated band on this site's scale. That is the 67th percentile nationally for tornado frequency. Within Missouri alone, Benton County ranks 41 of 115 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Benton County in NOAA's 76-year database. Of its 29 recorded tracks, 23 were weak (EF0-1) and 6 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 Benton County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
The storm that misses Benton County outright can still take its power out - outbreak-scale outages across Missouri are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Benton County's figure does not tell you
Benton County's figure is county-wide, not address-specific. Benton County covers about 704 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. Benton County has about 20,614 residents.
