Tornado Risk in Billings County, ND
Billings County, ND: what NOAA's tornado record says
7 tornado tracks have crossed Billings County since 1954 by NOAA's count, roughly one every 10.9 years - the Low band on this site's scale. That is the 20th percentile nationally for tornado frequency. Among 53 North Dakota counties in this dataset, Billings County ranks 53 for how often a tornado touches down.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Billings County in NOAA's 76-year database. Of its 7 recorded tracks, 7 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
North Dakota does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Billings County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
1,063 people live in Billings County, and a tornado outbreak's power loss usually reaches far more of North Dakota than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Billings County's figure does not tell you
Billings County's figure is county-wide, not address-specific. Billings County covers about 1,148 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. Billings County has about 1,063 residents.
