Tornado Risk in Roseau County, MN
Roseau County's tornado history, by the numbers
42 tornado tracks have crossed Roseau County since 1966 by NOAA's count, roughly one every 1.8 years - the High band on this site's scale. That is the 82nd percentile nationally for tornado frequency. Among 87 Minnesota counties in this dataset, Roseau County ranks 11 for how often a tornado touches down.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Roseau County in NOAA's 76-year database. Of its 42 recorded tracks, 39 were weak (EF0-1) and 3 significant (EF2-3).
Shelter and safe-room economics
Minnesota does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Roseau County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
The storm that misses Roseau County outright can still take its power out - outbreak-scale outages across Minnesota are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What Roseau County's figure does not tell you
Roseau County's figure is county-wide, not address-specific. Roseau County covers about 1,672 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. Roseau County has about 15,265 residents.
