Tornado Risk in Montgomery County, VA
Montgomery County, VA: what NOAA's tornado record says
5 tornado tracks have crossed Montgomery County since 1987 by NOAA's count, roughly one every 15.2 years - the Minimal band on this site's scale. That is the 17th percentile nationally for tornado frequency. Virginia has 133 counties in this dataset; Montgomery County ranks 66 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Montgomery County in NOAA's 76-year database. Of its 5 recorded tracks, 5 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 Montgomery County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
A direct hit is not required for Montgomery County to lose power - outbreak-wide outages across Virginia regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What Montgomery County's figure does not tell you
Montgomery County's figure is county-wide, not address-specific. Montgomery County covers about 387 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. Montgomery County has about 98,998 residents.
