Risk Overview

About Natural Disaster Risk in McLean County, North Dakota

McLean carries elevated but manageable risk

McLean County's composite score of 43.10 earns a Relatively Low rating—higher than most U.S. counties but still below the high-risk threshold. The county's exposure reflects meaningful hazard presence without reaching severe levels.

McLean ranks among higher-risk ND counties

At 43.10, McLean's score nearly doubles North Dakota's state average of 22.19, placing it in the upper half of state counties by risk. Still, the Relatively Low rating indicates the county remains well-managed and resilient.

Riskiest county in the immediate region

McLean's score of 43.10 exceeds all nearby counties including McHenry (11.74), McKenzie (25.03), and Mercer (13.87), making it the area's highest-risk location. Only Morton County (49.59) registers higher composite risk in the broader vicinity.

Tornado and flood risks dominate

Tornado risk reaches 45.55 in McLean—well above state typical exposure—and flood risk climbs to 33.11, creating dual concerns. Wildfire risk is also substantial at 76.97, while earthquake risk remains low.

Strengthen home against storms and floods

Confirm your policy covers both tornado/wind damage and flood risk; standard homeowners insurance excludes floods, so a separate policy may be needed. Reinforce your safe room, maintain gutters and drainage, and sign up for emergency alerts.

Risk Verdict

Natural hazard pressure in McLean County is below the national midpoint, with a composite score at the 43th percentile. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at McLean County's favorable 43th percentile ranking.

Hazard Breakdown

Wildfire risk is McLean County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 46th percentile nationally. Additional tracked hazards include flood (33th percentile), earthquake (15th percentile).

Preparedness Context

With wildfire ranked at the 77th percentile nationally, McLean 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 McLean County households to have on hand before fire season. Alongside wildfire, tornado at the 46th 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 McLean County households — and the insurance review is the one most often deferred by McLean County residents and most costly to skip when a fire event actually occurs.

Regional Context

McLean County is 20.9 composite risk points above the North Dakota average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.
