Risk Overview

About Natural Disaster Risk in Slope County, North Dakota

Slope County: extraordinarily low risk

With a composite risk score of just 0.64, Slope County ranks among the safest places in the entire United States. Your community faces minimal exposure to the natural disasters that threaten most American counties.

ND's safest county overall

Slope County's 0.64 score is far below North Dakota's state average of 22.19, making it the state's most resilient community by a substantial margin. This exceptional safety reflects low exposure across nearly all major hazard categories.

Safest in an already-safe region

Slope's 0.64 score edges out neighboring Bowman County (6.63) and Hettinger County (17.06), establishing it as the region's clear safety leader. Even within one of North Dakota's lowest-risk areas, Slope stands apart.

Wildfire is your only notable hazard

Wildfire risk (38.04) is the only significant threat in Slope County, while flood (0.57), tornado (5.50), and earthquake (0.60) risks remain negligible. Even your highest risk category remains modest compared to state and national standards.

Basic coverage is sufficient

Standard homeowners insurance provides robust protection in Slope County given the county's minimal disaster exposure. Confirm your policy covers wildfire as a precaution, and maintain basic emergency preparedness for severe weather.

Risk Advisory: Slope County

Risk Verdict

Slope County's natural disaster risk is among the lowest in the country, with a composite score at the 1th percentile nationally. Being ranked at the 1th percentile nationally is an advantage for Slope County — it means fewer statistically likely events, though basic readiness ensures households are covered when exceptions occur.

Hazard Breakdown

Wildfire risk is Slope County's dominant natural hazard, ranked at the 38th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 6th percentile nationally. Additional tracked hazards include earthquake (1th percentile), flood (1th percentile).

Preparedness Context

Wildfire is Slope County's top-ranked natural hazard at the 38th percentile nationally. Slope 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. A secondary tornado exposure at the 6th percentile nationally means Slope County residents face hazards from two distinct natural peril categories during different seasons. For Slope 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

The North Dakota county average exceeds Slope County's score by 21.6 composite points — placing this county in the lower-risk tier relative to its in-state peers.
