SALT LAKE CITY, Utah — A Winter Weather Advisory has been issued for northern Utah’s Wasatch Mountains, with forecasters warning of heavy snowfall and hazardous travel conditions beginning noon Sunday through noon Monday, according to the National Weather Service in Salt Lake City.

Snow totals and affected areas

Forecasters predict 4 to 8 inches of snow along U.S. Highway 89 through Logan Canyon and across the Monte Cristo summit, while the Bear River Mountains could see 8 to 12 inches of accumulation by Monday morning.

The advisory specifically covers the Wasatch Mountains north of I-80, including Cache County, Rich County, and Box Elder County’s higher elevations. Popular travel routes such as SR-39, Logan Canyon, and access roads to recreation areas like Tony Grove and Hardware Ranch may experience snow-packed conditions and limited visibility, especially overnight Sunday into early Monday.

Travel advisory and safety reminders

The Utah Department of Transportation (UDOT) is urging motorists to use extreme caution when traveling through mountain passes, particularly for those driving trailers, trucks, or vehicles without snow tires or chains.

“Travelers should expect rapidly changing conditions, including whiteout visibility at higher elevations,” the NWS warned.

Drivers can monitor live road conditions and closures at udottraffic.utah.gov before setting out.

Timing and forecast outlook

Snow is expected to begin midday Sunday, intensify Sunday night, and taper off by midday Monday. However, lingering flurries could continue across the northern peaks into Monday afternoon as colder air remains in place.

Temperatures in the valleys will drop into the mid-30s overnight, with mountain temperatures dipping into the teens and low 20s.

This marks the first significant snowfall event of the season for northern Utah’s higher elevations, signaling the transition into a more active late-October weather pattern.
