Tornado Risk in Lewis County, KY
Lewis County's tornado history, by the numbers
6 tornado tracks have crossed Lewis County since 1965 by NOAA's count, roughly one every 12.7 years - the Minimal band on this site's scale. That is the 18th percentile nationally for tornado frequency. Within Kentucky alone, Lewis County ranks 87 of 120 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Lewis County in NOAA's 76-year database. Of its 6 recorded tracks, 5 were weak (EF0-1) and 1 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 Lewis 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 Lewis County outright can still take its power out - outbreak-scale outages across Kentucky are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Lewis County's figure does not tell you
Lewis County's figure is county-wide, not address-specific. Lewis County covers about 483 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. Lewis County has about 12,875 residents.
