Salt Lake City, UT – Snow and isolated thunderstorms are creating sudden winter driving hazards above 8,500 feet across the Wasatch and western Uinta Mountains, with bursts capable of dropping up to 5 inches by late afternoon. Travel over high mountain passes could deteriorate quickly before 5 p.m. MST.
According to the National Weather Service in Salt Lake City, a Winter Weather Advisory remains in effect for elevations above 8,500 feet until 5 p.m. MST. Forecasters expect up to 3 inches of additional accumulation broadly, with embedded thunderstorms producing graupel and localized totals of 4 to 5 inches.
In the Wasatch Mountains north and south of I-80, including Brighton, Alta, and Logan Summit, snow showers may intensify rapidly, coating roadways in minutes. Drivers along I-80 near Parleys Summit and on Mirror Lake Highway in the western Uintas could encounter slushy pavement, reduced visibility under one mile, and brief heavy bursts this afternoon.
Utah Department of Transportation crews are monitoring conditions, but motorists should slow down, increase following distance, and check UDOT traffic cameras before heading into higher terrain. Conditions can change sharply with convective snow showers.
The advisory expires at 5 p.m. MST, though additional statements may be issued if thunderstorms prolong snowfall into the evening.
