How Likely Is a Tornado in Surry County, VA?
Surry County, VA: what NOAA's tornado record says
Surry County has recorded 9 tornado touches in NOAA's 76-year database, a rate of roughly one every 8.5 years - our Low band. Put another way: Surry County sees more tornado activity than 26% of US counties. Within Virginia alone, Surry County ranks 48 of 133 counties for tornado frequency.
Beyond the frequency band: violent history
7 weak and 2 significant tornadoes make up Surry County's 9-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Surry County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Virginia has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Virginia this pass.
What a direct hit isn't required for
Tornado outbreaks routinely knock out power across Virginia for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
What this number is, and is not
One caveat before relying on Surry County's number: it is county-wide, and it covers about 279 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Surry County has about 6,579 residents.
