Tornado Risk in Marshall County, KY
Marshall County's tornado history, by the numbers
27 tornado tracks have crossed Marshall County since 1951 by NOAA's count, roughly one every 2.8 years - the Elevated band on this site's scale. That is the 64th percentile nationally for tornado frequency. Kentucky has 120 counties in this dataset; Marshall County ranks 12 of them by frequency.
The number that matters more than frequency
Yes. Marshall County has recorded 2 EF4 or EF5 tornados - the strength FEMA's own safe-room guidance is built around, because a standard code-built house is not expected to survive those winds without a hardened room. A county can be lower-frequency overall and still carry this history.
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 Marshall County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Tornado outbreaks routinely knock out power across Kentucky for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
What Marshall County's figure does not tell you
Marshall County's figure is county-wide, not address-specific. Marshall County covers about 302 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. Marshall County has about 31,734 residents.
