Kernpunkte

Two avalanche problems confront skiers and riders today. First, newly created soft slabs could be triggered in steep, avalanche starting zones. Second, persistent slabs could be triggered directly by skiers and riders or step down from the release of the new soft slabs. Evaluate the terrain carefully, and come home to your friends and family this holiday season.

    New snow, combined with light to moderate winds, have created soft slabs six to 12 inches deep on leeward aspects at all elevations. Backcountry travelers are likely to trigger these slabs in steep, wind-loaded terrain at the upper elevations. These slabs will be less likely to trigger with a decrease in elevation where wind becomes less of a factor. Increasing wind and continued snowfall will add depth and volume throughout the day.

    At the upper elevations, faceted snow lies upon wind pack and sun crusts formed during the early December dry period. There, skiers and riders might be able to trigger persistent slabs up to an additional two feet. On north facing slopes above 9,000 feet, some potential may persist for hard slabs failing to early season weak layers near the ground.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Snowfall will begin this evening, with the heaviest snowfall occurring between 9 PM tonight and 3 PM Christmas day as a cold front moves from the northern portion of the forecast area to the south. Strong southwesterly ridgetop winds will veer to the northeast as the front passes. As the day progresses, snowfall intensity will decrease and become lighter in density. Ten to 15 inches of new snow could accumulate by Thursday evening.The general avalanche hazard could increase to CONSIDERABLE on Christmas Day if forecasted snowfall amounts materialize. New surface slabs will develop overnight and into Thursday. Backcountry travelers could trigger these slabs in steep, wind-loaded starting zones above 7,500 feet. At the upper elevations, skiers and riders might be able to trigger persistent slabs up to three feet deep failing on surfaces from the early December dry spell.
