Cheyenne, Wyoming – Travel in southern Wyoming’s high country is expected to become dangerous late Sunday night as another round of mountain snow moves into the Sierra Madre Range, bringing heavy accumulation and strong winds that could significantly reduce visibility.
According to the National Weather Service in Cheyenne, a Winter Weather Advisory is in effect from late Sunday night through Monday evening for the Sierra Madre Range. Snow totals of 6 to 12 inches are expected, with the heaviest snowfall occurring overnight and continuing through much of Monday. Winds may gust as high as 45 mph, leading to areas of blowing and drifting snow.
The greatest impacts are expected near Saratoga, Baggs, and along mountain routes connecting Carbon County with southern Wyoming backcountry areas. Snow-covered roads and near-whiteout conditions are possible at times, especially during periods of stronger wind. Travel across exposed passes could become hazardous, particularly for high-profile vehicles.
Lower elevations near Rawlins may see less accumulation, but wind-driven snow could still affect travel during heavier bursts. Emergency officials advise delaying non-essential mountain travel and ensuring vehicles are equipped with winter survival gear if travel is unavoidable.
Conditions are expected to gradually improve late Monday night as snow tapers off, though slick roads may linger into early Tuesday. Forecasters say additional advisories remain possible if snowfall or wind intensity increases. Residents and travelers should continue monitoring updates as the system moves through the region.
