Hazard Breakdown
Tornado risk is Fremont County's dominant natural hazard, ranked at the 46th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 37th percentile nationally. Additional tracked hazards include flood (18th percentile), earthquake (13th percentile), hurricane (0th percentile).
Preparedness Context
With tornado ranked at the 46th percentile nationally, Fremont County sits in a high-exposure zone where the difference between outcomes often comes down to proximity to a reinforced interior shelter and seconds of warning time. The secondary wildfire hazard at the 37th percentile nationally adds seasonal complexity to Fremont County's preparedness calendar, since wildfire and tornado risk often peak at different points in the year. For Fremont County households, safe rooms certified to FEMA 320/361 standards offer the highest protection during a direct tornado hit; households without a safe room should locate the innermost lowest-floor room in their building and practice the route to it before storm season.
