Tornado Risk in Traill County, ND
Traill County's tornado history, by the numbers
33 tornado tracks have crossed Traill County since 1953 by NOAA's count, roughly one every 2.3 years - the Elevated band on this site's scale. That is the 72nd percentile nationally for tornado frequency. Within North Dakota alone, Traill County ranks 24 of 53 counties for tornado frequency.
The number that matters more than frequency
Yes. Traill County has recorded 1 EF4 or EF5 tornado - the strength FEMA's own safe-room guidance is built around, because a standard code-built house is not expected to survive those winds without a hardened room. A county can be lower-frequency overall and still carry this history.
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 Traill County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in North Dakota often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Traill County's figure does not tell you
Traill County's figure is county-wide, not address-specific. Traill County covers about 862 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. Traill County has about 7,989 residents.
