Knox County, NE: Tornado Risk and Shelter Cost
Knox County, NE: what NOAA's tornado record says

Against the rest of the country, that is the 85th percentile for frequency. Nebraska has 93 counties in this dataset; Knox County ranks 25 of them by frequency.

Paying for it, if Knox County's history says you should
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally (around $7,645 typical). Nebraska's Nebraska Emergency Management Agency's Residential Tornado Safe Room Program covers 75% of an approved project - bringing a typical job down to roughly $722.5-$3,320 out of pocket, when the program is currently funded.
The gap a shelter does not cover
The storm that misses Knox County outright can still take its power out - outbreak-scale outages across Nebraska are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Knox County covers about 1,108 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Knox County has about 8,306 residents.
