How Likely Is a Tornado in Vermillion County, IN?
How likely is a tornado in Vermillion County, IN?
Vermillion County has recorded 10 tornado touches in NOAA's 76-year database, a rate of roughly one every 7.6 years - our Low band. Put another way: Vermillion County sees more tornado activity than 28% of US counties. Within Indiana alone, Vermillion County ranks 84 of 92 counties for tornado frequency.
Beyond the frequency band: violent history
8 weak and 2 significant tornadoes make up Vermillion County's 10-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Vermillion County's rating leads to
Indiana's Indiana Department of Homeland Security's Residential Safe Room Program is the number that matters for a Vermillion County homeowner: 75% of an approved shelter, capped at $5,000, cutting the typical $2,890-$13,280 national range to about $722.5-$8,280 net.
What a direct hit isn't required for
Tornado outbreaks routinely knock out power across Indiana 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 Vermillion County's number: it is county-wide, and it covers about 257 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. Vermillion County has about 15,516 residents.
