The strongest winter storm of the season is expected to move through Utah beginning Sunday, according to the National Weather Service.

Heavy snow is predicted along the Wasatch Front, with total accumulations of 5 inches to 10 inches in the valleys through Tuesday and accumulations on the benches of 1 feet to 2 feet.

“This looks to be the most significant storm for the region all winter season,” the weather service said on its website. “Those planning to travel through Tuesday should be prepared for winter driving conditions including snow covered roads and reduced visibilities.”

The weather service urges motorists to gas up before they begin traveling and to have winter storm survival kits in their vehicles. These kits should include warm blankets, extra clothing, extra food and water, a flashlight, a cellphone and batteries.

The Utah Avalanche Center said the danger of backcountry landslides on Sunday was “considerable” and could rise to “high” by Presidents Day, with new snow and strong winds creating areas of unstable snow. Both human-triggered and natural avalanches will be likely, the center said.

The advisory does not apply to operating ski areas where avalanche hazard reduction measures are performed.

Highs in the upper 20s to the 30s are predicted on Monday along much of the Wasatch Front. In Park City, the temperature is expected to top out in the teens.
