How Likely Is a Tornado in Kankakee County, IL?
How likely is a tornado in Kankakee County, IL?
Kankakee County has recorded 56 tornado touches in NOAA's 76-year database, a rate of roughly one every 1.4 years - our High band. Put another way: Kankakee County sees more tornado activity than 91% of US counties. Among 102 Illinois counties in this dataset, Kankakee County ranks 16 for how often a tornado touches down.
Beyond the frequency band: violent history
44 weak and 9 significant tornadoes make up Kankakee County's 56-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Kankakee County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Illinois 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 Illinois this pass.
What a direct hit isn't required for
Tornado outbreaks routinely knock out power across Illinois 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 Kankakee County's number: it is county-wide, and it covers about 676 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. Kankakee County has about 106,410 residents.
