Before the emergency — maps, tools, and the honest picture of what Wyoming throws at different parts of the state.
See WY hazardsWY hazard profile
Wyoming's open plains and mountain terrain make it one of the most dangerous winter driving states in the country. I-80 between Cheyenne and Rawlins — one of the nation's busiest freight corridors — closes dozens of times per year. The January 2019 blizzard stranded hundreds of vehicles on I-80 for 48+ hours. The Snowy Range, Wind River Range, and Bighorn Mountains generate extreme snowfall that isolates communities for days. Wyoming's high plains, sagebrush basins, and mountain forests burn every summer. The 2016 Badger Creek Fire burned 90,000+ acres in Carbon County. The 2012 Arapaho Fire near Buffalo burned 65,000 acres. Eastern Wyoming's dry grasslands can carry fire for hundreds of miles under wind-driven conditions. Fire season runs May through October across most of the state. Wyoming regularly records some of the coldest temperatures in the lower 48. Dubois, Lander, and Pinedale see -40°F or colder multiple times per winter. The Continental Divide forces Arctic air masses south through mountain passes. Rural communities depend on propane and heating oil — delivery disruptions during extreme cold events are a serious risk. Wind chills below -60°F occur in exposed areas.
Ice accumulation causes prolonged power outages and road closures across the state.

Insurance gaps
Standard homeowner's policies in Wyoming exclude flood damage. Flood insurance through the NFIP has a 30-day waiting period — it cannot be purchased when a storm is forecast. Check your declarations page annually to confirm your coverage limits and deductibles.
Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
