Risk Overview
About Natural Disaster Risk in Sublette County, Wyoming
Sublette ranks among the nation's safest
Sublette County's composite risk score of 21.63 places it in the Very Low category, well below both the state average of 37.86 and typical national risk profiles. Despite Wyoming's varied hazard exposure, Sublette stands out as a county with relatively modest natural disaster vulnerability. This favorable rating reflects manageable risk across most hazard categories.
Wyoming's lowest-risk county profile
Sublette County ranks among Wyoming's safest with a composite score of 21.63, roughly 56% lower than the state average of 37.86. The county's low overall risk is driven by minimal tornado and flood exposure, which significantly reduce its composite vulnerability. Only a handful of Wyoming counties match Sublette's favorable risk position.
Sublette benefits from protective geography
Sublette's composite score of 21.63 positions it favorably against nearby Sweetwater County (30.63) and Uinta County (16.70), with only Uinta showing slightly lower overall risk. The county avoids the elevated wildfire pressures affecting neighboring Teton and Sheridan counties. Sublette's geographic isolation and terrain help explain its consistently low hazard exposure.
Wildfire and earthquakes pose modest threats
Sublette's wildfire risk scores 87.72, which is notably elevated despite the county's low composite score—suggesting wildfire is the primary hazard of concern here. Earthquake risk reaches 76.21, a moderate exposure typical for western Wyoming. Tornado and flood risks remain minimal at 5.79 and 21.41 respectively.
Standard coverage sufficient for most residents
Sublette's very low overall risk means standard homeowners insurance provides adequate baseline protection for most residents, though wildfire coverage gaps should be addressed. Given the 87.72 wildfire risk score, ensure your policy explicitly includes wildfire damage or add supplemental coverage. Annual maintenance to reduce brush and dead wood on your property remains a practical, cost-effective safeguard.

Risk Verdict
Sublette County's natural disaster risk is among the lowest in the country, with a composite score at the 22th percentile nationally. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Sublette County's favorable 22th percentile ranking.
Hazard Breakdown
Wildfire risk is Sublette County's dominant natural hazard, ranked at the 88th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 76th percentile nationally. Additional tracked hazards include flood (21th percentile), tornado (6th percentile).
Preparedness Context
Wildfire is Sublette County's top-ranked natural hazard at the 88th percentile nationally. Sublette 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 earthquake exposure at the 76th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. For Sublette 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 Wyoming county average exceeds Sublette County's score by 16.2 composite points — placing this county in the lower-risk tier relative to its in-state peers.
