Risk Overview

About Natural Disaster Risk in Washakie County, Wyoming

Washakie's risk sits below the national norm

Washakie County scores 24.36 on the composite risk index, earning a Very Low rating and remaining below typical national hazard profiles. This favorable score reflects the county's location in north-central Wyoming and balanced exposure across hazard categories. Washakie residents benefit from relatively stable geography with no extreme natural disaster vulnerabilities.

Among Wyoming's safer counties

Washakie's composite score of 24.36 falls well below the state average of 37.86, placing it in Wyoming's safer half of county rankings. The county avoids the elevated risks present in northwestern Wyoming while maintaining reasonable hazard exposure. Washakie's position reflects its location in central Wyoming's more stable geological and climatic region.

Washakie compares favorably to regional peers

Washakie (24.36) ranks near Sublette County (21.63) and Sweetwater County (30.63) in overall risk, forming a relatively safe corridor in central Wyoming. The county's score exceeds only Uinta (16.70) and Weston (7.89) but remains significantly below Sheridan (65.20) and Teton (70.64). Washakie's middle positioning reflects its transitional geography in Wyoming's interior.

Wildfire and earthquake drive Washakie hazards

Washakie's wildfire risk reaches 66.73, the county's highest hazard score and reflecting extensive grassland and forest exposure across the region. Earthquake risk scores 71.72, a moderate-to-significant exposure reflecting the county's position near seismic zones. Flood and tornado risks remain low at 48.60 and 14.98 respectively.

Wildfire and earthquake coverage recommended

Washakie residents should confirm wildfire coverage in their homeowners policy given the county's 66.73 wildfire risk score, as standard policies often exclude this hazard. Earthquake insurance is worth evaluating given the 71.72 earthquake risk score, particularly for newer homes in more vulnerable locations. Maintain defensible space around your property and review your policy annually to ensure adequate coverage limits.

Alongside earthquake exposure, Washakie County's wildfire risk at the 67th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Building age matters for earthquake risk in Washakie County: structures built before local seismic code adoption are statistically more vulnerable. Contacting the local building department about retrofit programs can reveal whether your structure qualifies for mitigation assistance.
