A winter storm warning has been issued for Utah's mountains, but just light snow is forecast for the valleys Friday and Friday night.

Four to 8 more inches of snow are expected in the northern ranges and 8 to 12 inches in southern mountains, said William J. Alder, meteorologist in charge of the Salt Lake office of the National Weather Service."Just marginal amounts of snow are expected in the valleys. It probably won't stick," Alder said.

Several areas of the state received welcome snow in a storm that began Thursday. Duck Creek, in Kane County, reported 20 inches.

Skies should be partly cloudy with a few showers around the state during the remainder of the weekend.

For those concerned about water for the months ahead, Alder gave additional information on snow totals since Thursday: 5 to 7 inches of new snow, northern mountains, with Brian Head ski resort, Iron County, reporting 8 inches. Water amounts received, in inches, were: Hurricane, 1.08; Alta, 0.91; Blanding, 0.40; Bryce Canyon, 0.28; St. George, 0.46; Kanab, 0.49; Salt Lake International Airport and Holladay, both 0.02; Provo, 0.21; Delta, 0.2; and Zion National Park, 0.37.

The Weather Service said travel is expected to be hazardous over the next 24 to 36 hours in the Utah mountains. Delaying travel until later in the weekend would be best. However, if motorists must travel they should prepare for adverse weather conditions, meteorologists said.

Livestock owners across the state were advised to be prepared for cool, wet weather during the next few days. Temperatures will remain in the 40s during the day and in the 20s and 30s during the night.
