How Likely Is a Tornado in Brown County, KS?
Brown County's tornado history, by the numbers
Brown County has recorded 47 tornado touches in NOAA's 76-year database, a rate of roughly one every 1.6 years - our High band. Put another way: Brown County sees more tornado activity than 85% of US counties. Kansas has 105 counties in this dataset; Brown County ranks 49 of them by frequency.
Beyond the frequency band: violent history
35 weak and 11 significant tornadoes make up Brown County's 47-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Brown County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Kansas 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 Kansas this pass.
What a direct hit isn't required for
Power loss after a tornado outbreak in Kansas often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What this number is, and is not
One caveat before relying on Brown County's number: it is county-wide, and it covers about 571 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. Brown County has about 9,142 residents.
