A winter weather advisory is in effect for the Western Uinta Mountains and the Wasatch Mountains south of I-80 until 6 a.m. MDT Wednesday. The National Weather Service Salt Lake City issued the advisory, noting that winter driving conditions are expected in these regions.
In the Western Uinta Mountains, including Moon Lake and Mirror Lake, additional snow accumulations of 8 to 14 inches are possible, particularly at elevations above 9,000 feet. Seasonal roads, such as Bald Mountain Pass, remain open but may pose a significant risk to travelers who are under-prepared. High elevation routes may experience periods of accumulating road snow.
Within the Wasatch Mountains south of I-80, snow is expected, specifically for elevations above 8,500 feet. Total accumulations of 3 to 6 inches are expected in upper Little and Big Cottonwood Canyon, with higher amounts expected for elevations above 9,000 feet. While minor accumulations are anticipated for upper Little and Big Cottonwood Canyon, Guardsman Pass is expected to see higher snowfall potential.
The advisory also covers the Wind River Mountains East and West. Snow is expected, with accumulations of 3 to 12 inches predicted for elevations of 9,000 feet and above, while elevations up to 9,000 feet may see 3 inches of snow. The time of maximum impact is expected Tuesday afternoon into Tuesday night, which could make travel difficult across the backcountry and impact commutes across South Pass.
In the Ruby Mountains and East Humboldt Range in Elko, a winter weather advisory remains in effect until 5 p.m. PDT Tuesday afternoon. This advisory includes the possibility of additional snow accumulations between 5 and 10 inches and notes that travel could be difficult.
