Tornado Risk in York County, VA
York County, VA: what NOAA's tornado record says
9 tornado tracks have crossed York County since 1951 by NOAA's count, roughly one every 8.5 years - the Low band on this site's scale. That is the 27th percentile nationally for tornado frequency. Within Virginia alone, York County ranks 45 of 133 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in York County in NOAA's 76-year database. Of its 9 recorded tracks, 8 were weak (EF0-1) and 1 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 York 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 York County outright can still take its power out - outbreak-scale outages across Virginia are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What York County's figure does not tell you
York County's figure is county-wide, not address-specific. York County covers about 105 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. York County has about 71,410 residents.
