Risk Overview

About Natural Disaster Risk in Sheridan County, North Dakota

Sheridan's risk sits well below average

Sheridan County's composite risk score of 5.03 earns a "Very Low" rating, placing it among the safest counties nationally. Your community enjoys substantially lower natural disaster exposure than most U.S. counties.

One of ND's lowest-risk counties

At 5.03, Sheridan County ranks significantly below North Dakota's state average of 22.19, making it one of the state's most resilient communities. This exceptionally low score reflects protection from the hazards that threaten other regions.

Comparable to fellow low-risk neighbors

Sheridan's 5.03 score rivals nearby Slope County (0.64) as one of the region's safest places, though both exceed the averages seen in central North Dakota. McKenzie County to the north faces notably higher wildfire exposure.

Wildfire and tornado are top concerns

Wildfire risk (63.30) is your county's highest hazard score, followed by tornado risk (22.42), reflecting typical Great Plains exposure patterns. Both scores remain manageable within the context of Sheridan's overall very low composite risk.

Baseline coverage is your safeguard

Standard homeowners insurance adequately covers Sheridan County's modest natural disaster risks. Review your policy annually and ensure you have emergency supplies and a weather safety plan for tornado season.

Risk Verdict

Hazard Breakdown

Wildfire risk is Sheridan County's dominant natural hazard, ranked at the 63th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 22th percentile nationally. Additional tracked hazards include earthquake (6th percentile), flood (4th percentile).

Preparedness Context

With wildfire ranked at the 63th percentile nationally, Sheridan 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 Sheridan County households to have on hand before fire season. The county's tornado exposure at the 22th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Sheridan County households — and the insurance review is the one most often deferred by Sheridan County residents and most costly to skip when a fire event actually occurs.

Regional Context

Sheridan County's composite risk score sits 17.2 points below the North Dakota county average, reflecting a more favorable hazard environment than the state typical.
