Risk Overview

About Natural Disaster Risk in Walsh County, North Dakota

Walsh County remains very low risk nationally

Despite a composite score of 29.01, Walsh County ranks as Very Low when measured against national disaster risk standards. This reflects North Dakota's overall favorable position relative to high-risk regions nationwide.

Slightly above North Dakota's average risk

Walsh County's 29.01 score exceeds the state average of 22.19, placing it in the middle tier of North Dakota counties. Wildfire risk particularly drives this elevation above the state norm.

More exposed than Traill, safer than Ward

Walsh County (29.01) sits between lower-risk Traill County (11.01) and higher-risk Ward County (64.76) in the eastern part of the state. Its wildfire score of 79.17 is notably elevated compared to Traill's 23.31.

Wildfires and tornadoes lead the threats

Wildfire risk reaches 79.17 in Walsh County, a significant hazard that demands attention despite the county's overall Very Low rating. Tornado risk (40.27) and flood risk (35.40) also merit preparation, while earthquakes remain minimal.

Prioritize wildfire and tornado coverage

Walsh County residents should ensure homeowners insurance explicitly covers wildfire damage, as standard policies sometimes exclude it. Create defensible space around your home and develop a family tornado plan for spring and early summer.

Risk Verdict

Walsh County carries a low natural disaster risk burden, scoring at the 29th percentile under the FEMA National Risk Index. Walsh County's 29th 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 Walsh County's dominant natural hazard, ranked at the 79th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 40th percentile nationally. Additional tracked hazards include flood (35th percentile), earthquake (7th percentile).

Preparedness Context

Wildfire ranks as Walsh County's primary hazard at the 79th percentile nationally. For Walsh County households in high-WUI areas, go-bag readiness — the ability to leave within 15 minutes — is more important than shelter-in-place planning for most residential properties. A secondary tornado exposure at the 40th percentile nationally means Walsh County residents face hazards from two distinct natural peril categories during different seasons. Walsh County county's local emergency management office publishes community-specific wildfire risk assessments and evacuation zone maps; households should review their zone assignment and sign up for zone-specific alerts.

Regional Context

Walsh County falls 6.8 points above North Dakota's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
