How Likely Is a Tornado in Osborne County, KS?
Osborne County's tornado history, by the numbers
Osborne County has recorded 44 tornado touches in NOAA's 76-year database, a rate of roughly one every 1.7 years - our High band. Put another way: Osborne County sees more tornado activity than 83% of US counties. Within Kansas alone, Osborne County ranks 56 of 105 counties for tornado frequency.
Beyond the frequency band: violent history
1 tornado touching Osborne County reached violent (EF4-5) strength since 1950. That single fact carries more weight for the shelter decision than the county's overall frequency band.
The dollar figure Osborne 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
The storm that misses Osborne County outright can still take its power out - outbreak-scale outages across Kansas are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What this number is, and is not
One caveat before relying on Osborne County's number: it is county-wide, and it covers about 893 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. Osborne County has about 3,353 residents.
