Risk Overview

About Natural Disaster Risk in Morton County, North Dakota

Morton County faces elevated disaster exposure

Morton County's composite risk score of 49.59 earns a Relatively Low rating but represents the highest exposure among the counties reviewed. While still below high-risk thresholds, Morton faces notably greater multi-hazard challenges than typical U.S. counties.

Morton carries the highest state risk reviewed

At 49.59, Morton's score far exceeds North Dakota's average of 22.19—more than double—positioning it among the state's highest-risk counties. The Relatively Low rating reflects that even the state's most exposed areas remain manageable.

Riskiest county in central North Dakota

Morton's 49.59 score surpasses all nearby counties, including McLean (43.10), making it the region's most hazard-exposed location. It stands substantially above the northwestern counties of McHenry, McKenzie, and Mercer.

Tornado and flood risks are critical

Morton County's tornado risk soars to 57.35—the highest reviewed—while flood risk reaches 40.43, creating a dual threat. Wildfire risk is also elevated at 73.92, requiring comprehensive hazard awareness.

Build comprehensive disaster coverage now

Obtain separate flood insurance, ensure wind/tornado coverage is included in your homeowners policy, and verify wildfire protection. Invest in a well-stocked safe room and develop a family communication plan for rapid evacuations.

Risk Verdict

Morton County has a below-average natural disaster risk profile, scoring at the 50th percentile nationally under FEMA's National Risk Index. Morton County's 50th percentile ranking is favorable, though every county carries at least one natural hazard worth knowing — reviewing the specific risks listed above helps households focus their preparedness where it matters most.

Hazard Breakdown

Wildfire risk is Morton County's dominant natural hazard, ranked at the 74th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 57th percentile nationally. Additional tracked hazards include flood (40th percentile), earthquake (7th percentile).

Preparedness Context

Wildfire is Morton County's top-ranked natural hazard at the 74th percentile nationally. Morton County residents should assess whether their property lies within or adjacent to a Wildland-Urban Interface (WUI) zone, where ember transport and rapid spread pose the highest risk. The county's tornado exposure at the 57th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. For Morton County households, a practiced evacuation plan — with a primary and backup route designated before a fire occurs — provides more protection than any structural improvement when a wildfire approaches fast-moving terrain.

Regional Context

Morton County's composite risk score sits 27.4 points above the North Dakota county average, placing it among the more hazard-exposed counties in the state.

The highest-risk hazard is wildfire at the 74th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Morton County risk compare to the North Dakota average?
Morton County's composite risk percentile is 50th, compared to the North Dakota state average of 22th percentile. The state's overall risk rating is Very Low. This means Morton County faces higher natural disaster risk than the typical county in North Dakota.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Morton County higher risk than average?
Morton County's composite risk score of 50th percentile is above the North Dakota state average of 22th percentile. This elevated risk is driven by wildfire exposure (74th percentile), along with tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
