How Likely Is a Tornado in Richardson County, NE?
Richardson County's tornado history, by the numbers
Richardson County has recorded 22 tornado touches in NOAA's 76-year database, a rate of roughly one every 3.5 years - our Moderate band. Put another way: Richardson County sees more tornado activity than 54% of US counties. Nebraska has 93 counties in this dataset; Richardson County ranks 71 of them by frequency.
Beyond the frequency band: violent history

The dollar figure Richardson County's rating leads to
Nebraska's Nebraska Emergency Management Agency's Residential Tornado Safe Room Program is the number that matters for a Richardson County homeowner: 75% of an approved shelter, cutting the typical $2,890-$13,280 national range to about $722.5-$3,320 net.
What a direct hit isn't required for
A direct hit is not required for Richardson 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 Richardson County's number: it is county-wide, and it covers about 552 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. Richardson County has about 7,666 residents.
