Furnas County, NE: what NOAA's tornado record says

The dollar figure Furnas 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
4,468 people live in Furnas 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 Furnas County's number: it is county-wide, and it covers about 719 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. Furnas County has about 4,468 residents.
