I80 Weather Wyoming & Live Radar

Interstate 80 in Wyoming is one of the most weather-sensitive stretches of highway in the United States. Running west to east across the state’s high plains and mountain basins, I-80 regularly experiences extreme and fast-changing weather conditions that can impact both personal travel and commercial freight routes.

Common Weather Conditions on I-80 in Wyoming

• Winter Snow & Ice:
  From October through April, I-80 in Wyoming is prone to snowstorms, blizzards, and black ice. The corridor runs at elevations of 6,000–8,000 feet, especially near Rawlins, Laramie, and the Elk Mountain region, where whiteout conditions and sub-zero wind chills are common. Sudden snow squalls and icy patches can reduce visibility and cause rapid lane closures.
• High Winds Year-Round:
  Strong crosswinds are a constant threat on I-80, particularly between Rawlins and Laramie. Gusts frequently exceed 60 mph, posing rollover risks for high-profile vehicles like semis, RVs, and box trucks. Wyoming DOT often issues wind advisories or even prohibits light or empty trailers from traveling during extreme wind events.
• Fog, Dust, and Thunderstorms:
  In spring and summer, travelers may encounter dense morning fog, especially near river valleys. Dry spells can also lead to blowing dust, reducing visibility across the open prairie. From May to August, severe thunderstorms can bring hail, lightning, and brief downpours that affect driving conditions.

Seasonal Hazards & Closures

• Frequent Winter Closures:
  Sections of I-80 — especially between Evanston and Cheyenne — are frequently closed due to winter storms, crashes, or multi-vehicle pileups. The Wyoming Department of Transportation (WYDOT) provides real-time updates on closures, chain laws, and weather alerts.
• Chain Laws & Traction Requirements:
  During heavy snow, chain laws may go into effect for commercial vehicles. Drivers should always carry approved chains and know how to use them. Even when open, I-80 can become slick quickly, so it’s important to monitor traction conditions regularly.
