Tornado Risk in Wilson County, TN
Wilson County, TN: what NOAA's tornado record says
45 tornado tracks have crossed Wilson County since 1955 by NOAA's count, roughly one every 1.7 years - the High band on this site's scale. That is the 85th percentile nationally for tornado frequency. Tennessee has 95 counties in this dataset; Wilson County ranks 5 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Wilson County in NOAA's 76-year database. Of its 45 recorded tracks, 32 were weak (EF0-1) and 13 significant (EF2-3).
Shelter and safe-room economics
Tennessee does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Wilson County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
169,948 people live in Wilson County, and a tornado outbreak's power loss usually reaches far more of Tennessee than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Wilson County's figure does not tell you
Wilson County's figure is county-wide, not address-specific. Wilson County covers about 571 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. Wilson County has about 169,948 residents.
