In Utah, meteorologists warned of heavy snow in the Wasatch Mountains south of I-80, the Central Mountains, Southern Mountains and the Western Uinta Mountains, including along some interstates. "Winter driving conditions can be expected along all mountain routes, including higher passes along I-15 and I-70," the NWS office in Salt Lake City warned.

More than a foot of heavy, blowing snow is expected to fall on Telluride and other cities around Colorado’s San Juan Mountains this weekend, making travel dangerous.
