SALT LAKE CITY — A backcountry avalanche warning was in effect Monday for much of northern Utah after a Christmas storm dumped more than a foot of snow in the upper elevations and several inches along the Wasatch Front.

At least 16 inches of snow had fallen at Park City, with nearly 8 inches at West Weber and 5 inches at Bountiful and South Ogden, the National Weather Service said.

Salt Lake International Airport reported 4 inches of new snow on the ground. Logan had 3.8 inches.

The snow was expected to end by Monday evening, but the avalanche warning was in effect through 6 a.m. Tuesday for the Bear River Range, western Uintas and all the Wasatch range, including Ogden, Provo, Salt Lake and the Park City area.

The U.S. Forest Service's Utah Avalanche Center said the danger is high because the wet snow is especially prone to slide.

The storm moved in on the heels of unseasonably warm weather, especially in southern Utah, where the high temperature on Saturday tied the record of 52 degrees in Cedar City set in 2014, the weather service said.
