Tornado Risk in Cheyenne County, NE
Cheyenne County, NE: what NOAA's tornado record says
73 tornado tracks have crossed Cheyenne County since 1951 by NOAA's count, roughly one every year - the High band on this site's scale. That is the 95th percentile nationally for tornado frequency. Within Nebraska alone, Cheyenne County ranks 7 of 93 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Cheyenne County in NOAA's 76-year database. Of its 73 recorded tracks, 58 were weak (EF0-1) and 8 significant (EF2-3).
Shelter and safe-room economics
Nebraska's Nebraska Emergency Management Agency's Residential Tornado Safe Room Program is the number that matters for a Cheyenne County homeowner: 75% of an approved shelter, cutting the typical $2,890-$13,280 national range to about $722.5-$3,320 net.
Power after the storm, not just shelter during it
9,602 people live in Cheyenne 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 Cheyenne County's figure does not tell you
Cheyenne County's figure is county-wide, not address-specific. Cheyenne County covers about 1,196 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Cheyenne County has about 9,602 residents.
