Riverton, WY — A powerful winter storm is pounding Wyoming’s mountain ranges this morning, bringing heavy snowfall, intense winds, and rapidly worsening travel conditions. Winter Storm Warnings remain in effect through this afternoon, and forecasters say snowfall could intensify through the midday hours.
Wyoming Braces for Severe Mountain Snowfall
The National Weather Service Riverton office reports that “an additional 5 to 12 inches of snow is expected in the Teton, Gros Ventre, Salt River, and Wyoming Ranges,” with higher elevations potentially reaching “15 to 20 more inches.” Gusty winds near 45 mph—and peak gusts close to 60 mph—will continue to create blowing and drifting snow, severely reducing visibility for travelers.
Conditions are especially hazardous for anyone attempting to cross major mountain passes, where snowfall rates may increase sharply during the late-morning hours.
Forecast Details Across Wyoming’s Mountain Ranges
A separate Winter Storm Warning remains in place for the western Bighorn Mountains. Forecasters note that “another 8 to 15 inches” is likely across central and northern sections, with the highest elevations possibly reaching “up to 20 inches.” Southern Bighorn zones may see 1 to 8 inches depending on elevation and band placement.
The National Weather Service highlights that the “heaviest snow is likely between 5 a.m. and noon,” creating a particularly dangerous window for morning travel.
Mountain Passes Facing Harshest Conditions
Multiple major routes are expected to experience rapid snow buildup, low visibility, and severe drifting:
- Teton Pass
- Togwotee Pass
- Salt River Pass
- Granite Pass
- Powder River Pass
Drivers should be prepared for near-whiteout conditions and rapidly changing road surfaces. Even short trips may become challenging as winds funnel through higher terrain.
Safety Guidance from the National Weather Service
Meteorologists are urging residents and travelers to take the storm seriously and plan for delays. Officials warn that “travel may be very difficult today” across the mountain corridor and advise keeping emergency supplies in all vehicles.
Recommended supplies include:
- Food and water
- Warm clothing and blankets
- Flashlight and backup batteries
- Fully charged phone
- Basic first-aid items
Anyone traveling toward western or northern Wyoming should check updated snowfall graphics at weather.gov/riw/winter and review real-time road conditions at wyoroad.info before heading out.
When Conditions May Improve
Snowfall intensity is expected to begin tapering later this afternoon, but winds will remain strong through the evening, continuing to cause drifting and visibility issues. Plow crews are preparing for long hours as the region works through the deep accumulation left behind by the storm.
Road improvements may be slow, especially at higher elevations, where the combination of wind and snowfall will likely keep travel difficult into the night.
Conclusion
Wyoming’s mountains are facing one of the strongest early-season storms so far, with heavy snow, damaging winds, and treacherous driving conditions expected through midday. Residents and visitors should monitor forecasts closely and avoid unnecessary travel while the Winter Storm Warnings remain active.
