Winter Weather Advisories are in effect across the Intermountain West, including Utah’s Wasatch and Uinta mountains near Alta, Brighton and Mirror Lake Highway, as early-season snow arrives Monday and Tuesday.
Advisories also cover Nevada’s Ruby Mountains and Wyoming’s Wind River Mountains. Drivers should expect slick roads and prepare for winter conditions at higher elevations.
