How Likely Is a Tornado in Thurston County, NE?
Thurston County's tornado history, by the numbers
Thurston County has recorded 15 tornado touches in NOAA's 76-year database, a rate of roughly one every 5.1 years - our Low band. Put another way: Thurston County sees more tornado activity than 40% of US counties. Within Nebraska alone, Thurston County ranks 85 of 93 counties for tornado frequency.
Beyond the frequency band: violent history
1 tornado touching Thurston 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 Thurston County's rating leads to
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.
What a direct hit isn't required for
A direct hit is not required for Thurston County to lose power - outbreak-wide outages across Nebraska regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What this number is, and is not
One caveat before relying on Thurston County's number: it is county-wide, and it covers about 394 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. Thurston County has about 6,637 residents.
