Tornado Risk in Alleghany County, VA
Alleghany County, VA: what NOAA's tornado record says
Zero tornado tracks recorded in Alleghany County since 1950, per NOAA's Storm Prediction Center. That reflects the actual geography, not a hole in the record. That is the 2nd percentile nationally for tornado frequency. Within Virginia alone, Alleghany County ranks 125 of 133 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Alleghany County in NOAA's 76-year database. Of its 0 recorded tracks, 0 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
Virginia does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Alleghany County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in Virginia often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Alleghany County's figure does not tell you
Alleghany County's figure is county-wide, not address-specific.
