Tornado Risk in Coffee County, TN
Coffee County, TN: what NOAA's tornado record says
29 tornado tracks have crossed Coffee County since 1957 by NOAA's count, roughly one every 2.6 years - the Elevated band on this site's scale. That is the 68th percentile nationally for tornado frequency. Within Tennessee alone, Coffee County ranks 13 of 95 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Coffee County in NOAA's 76-year database. Of its 29 recorded tracks, 22 were weak (EF0-1) and 7 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 Coffee County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
61,285 people live in Coffee 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 Coffee County's figure does not tell you
Coffee County's figure is county-wide, not address-specific. Coffee County covers about 429 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. Coffee County has about 61,285 residents.
