Winter Storm Warnings Remain In Effect for Mountains

Posted By on Mon, Dec 17, 2012 at 9:10 AM

Hazardous weather continues this morning across the region's mountain areas, with blowing and drifting snow responsible for challenging driving conditions.

A strong cold front pushed through Bend, Ore., early today and the National Weather Service office in Boise said the front was moving quickly eastward, with bands of precipitation just ahead of the front.

Near-whiteout conditions are expected on Idaho Highways 55, 21 and 22 as bands of heavy snow continue through much of the morning. The 12-mile stretch of Idaho Highway 21, known as "avalanche alley" closed early this morning, blocking traffic between the Grandjean junction turnoff and Banner summit. A winter storm warning remains in effect for the west-central and Boise Mountains and the Camas Prairie. A blizzard warning remains in effect until 1 p.m. Mountain Time for the southern Blue Mountains of Oregon and the northern Blue Mountains of Washington.

In the Treasure Valley, temperatures were far too warm to bring snow to the morning commute, but much colder temperatures are expected to take hold later in the week. Overnight lows are expected to drop into the 20s tonight with Wednesday's high temperature forecast to be near freezing.
