Risk Overview

About Natural Disaster Risk in Roseau County, Minnesota

Roseau faces moderate national risk

Roseau County's composite risk score of 43.86 slightly exceeds the national average, carrying a Relatively Low rating. The score masks a significant concentration of wildfire danger that sets this county apart from most peers.

Slightly above Minnesota's average

At 43.86, Roseau County's risk score edges above Minnesota's state average of 42.38, reflecting above-average exposure to specific hazards. The county's Relatively Low rating indicates manageable but non-trivial disaster risk.

Wildfire risk distinguishes Roseau

Roseau County (43.86) shares similar overall risk with other northern Minnesota counties, but its wildfire score of 91.00 is extraordinary—the highest among all counties in this comparison. This unique vulnerability sets Roseau apart from neighbors like Koochiching and Lake counties.

Wildfire danger is extreme

Roseau County's wildfire risk of 91.00 is by far its dominant hazard and among the highest in Minnesota, driven by vast forested landscapes and dry conditions. Flooding poses a secondary threat at 59.96, while tornado and earthquake risks remain minimal.

Prioritize wildfire preparedness

Roseau County residents must focus on wildfire mitigation: clear vegetation within 30 feet of structures, use fire-resistant roofing, and maintain comprehensive homeowners insurance. Consider brush clearing as a annual priority and develop an evacuation plan for wildfire season.

Risk Verdict

Natural hazard pressure in Roseau County is below the national midpoint, with a composite score at the 44th percentile. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Roseau County's favorable 44th percentile ranking.

Hazard Breakdown

Wildfire risk is Roseau County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 60th percentile nationally. Additional tracked hazards include tornado (17th percentile), earthquake (2th percentile).

Preparedness Context

With wildfire ranked at the 91th percentile nationally, Roseau County is in a zone where air quality can deteriorate rapidly before structures are threatened. An N95 respirator and a HEPA air purifier are practical items for Roseau County households to have on hand before fire season. Alongside wildfire, flood at the 60th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Roseau County households — and the insurance review is the one most often deferred by Roseau County residents and most costly to skip when a fire event actually occurs.

Regional Context

Roseau County's risk score is broadly comparable to the Minnesota county average, with a 1.5-point gap that places the county near the center of the state's hazard distribution.
