UPDATE: Winter Storm, Avalanche Warnings in Central Idaho


UPDATE: December 14, 2015  3:30 p.m.

Officials with Idaho Power reported Monday that a winter storm had triggered power outages for some customers in McCall, Donelly, Yellow Pine, Council, Mountain Home and Idaho City.

“We’ve got 12 to 15 inches of heavy, wet snow combined with wind over the weekend that caused lines to break and trees and branches to fall into our power lines,” Regional Operations Manager Tony Calzacorta said. “Crews are using snow shoes and snow machines to get through the trees to do the necessary repairs.” 

By mid-afternoon Monday, crews were concentrating efforts in the the Valley County communities of McCall, Donelly and Yellow Pine, in addition to some areas of Council and Idaho City. Approximately 350 customers were still without service in the McCall, Yellow Pine, Warm Lake and Council areas by 2:30 p.m.

“Walking through knee-deep snow, not to mention the wet, cold and miserable conditions, has been tough,” Calzacorta said. “They’re sympathetic to our customers and are working safely to get the power back on.”

The Treasure Valley woke up Monday morning to overcast skies and hint of light showers, but much of southern and eastern Idaho began the work week with severe winter weather—triggering scores of spin-offs on roadways, delays or closures of schools, and even avalanche warnings in the Sawtooth National Forest.

The avalanche center in Ketchum issued a backcountry avalanche warning early Monday—in effect until Tuesday morning—for the Soldier Mountains, including mountains near Fairfield. Three feet of new snow and strong winds were producing widespread areas of unstable snow, according to the National Weather Service. 

Magic Valley law enforcement was urging motorists to slow down and give some extra space, reporting a number of slideoffs throughout southern Idaho. Street crews in Twin Falls said they were out in force, applying sand and salt to the roads, "but it's going to take some time."

The weather service also issued a winter storm warning in effect for the cities of Hailey, Ketchum, Bellevue, Stanley and Clayton for Monday morning, saying winds up to 30 mph had triggered blowing and drifting snow conditions.

Another band of snow was expected to in the area by mid-week with Boise's forecast calling for snow throughout the day and night Wednesday, Dec. 16 and Thursday, Dec. 17.
