Tornado Risk in Lyon County, KY
Lyon County, KY: what NOAA's tornado record says
14 tornado tracks have crossed Lyon County since 1970 by NOAA's count, roughly one every 5.4 years - the Low band on this site's scale. That is the 38th percentile nationally for tornado frequency. Within Kentucky alone, Lyon County ranks 36 of 120 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Lyon County in NOAA's 76-year database. Of its 14 recorded tracks, 10 were weak (EF0-1) and 4 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 Lyon 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 Lyon 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 Lyon County's figure does not tell you
Lyon County's figure is county-wide, not address-specific. Lyon County covers about 214 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. Lyon County has about 9,078 residents.
