How Likely Is a Tornado in Blaine County, NE?
Blaine County's tornado history, by the numbers
Blaine County has recorded 11 tornado touches in NOAA's 76-year database, a rate of roughly one every 6.9 years - our Low band. Put another way: Blaine County sees more tornado activity than 30% of US counties. Nebraska has 93 counties in this dataset; Blaine County ranks 90 of them by frequency.
Beyond the frequency band: violent history
1 tornado touching Blaine 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 Blaine 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
454 people live in Blaine County, and a tornado outbreak's power loss usually reaches far more of Nebraska than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What this number is, and is not
One caveat before relying on Blaine County's number: it is county-wide, and it covers about 711 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. Blaine County has about 454 residents.
