Highlights

Pockets of wind slab, which formed on Thursday and Friday, could be triggered by backcountry travelers in steep, wind loaded terrain above 8,500 feet. Evaluate the snow and terrain carefully, and be cautious when entering steep terrain with wind affected snow. Below 8,500 feet, skiers and riders might be able to trigger an isolated pocket up to a foot deep in areas that were snow covered prior to the Thursday's storm cycle. Avalanches are unlikely in terrain where the recent snow fell onto bare ground.

    Snowfall on Thursday was accompanied by strong westerly ridgetop which created dense wind slabs at the mid and upper elevations. Strong northwesterly winds on Friday continued to transport snow from windward to lee ward aspects. These slabs lie upon a variety of old snow surfaces, which include crusts, wind pack and faceted snow. Backcountry travelers venturing into steep, wind loaded terrain above 8,500 feet could trigger these slabs to depths of 6 to 18 inches.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies will be mostly clear on Sunday as high pressure continues to dominate the weather pattern. Overnight lows in the mountains will be near ten degrees before climbing to around 30 during the day. Inverted temperatures will develop during the night with valley lows in the single digits. During the day, the lower elevations temperatures will rebound to around freezing. Westerly ridgetop winds will range from 10 to 20 miles per hour.On Sunday, the general avalanche hazard is expected to be Moderate above 8,500 feet. There, backcountry travelers venturing into steep, wind loaded terrain could trigger pockets of recently developed wind slabs six to eighteen inches in depth. Below 8,500 feet, skiers and riders might be able to trigger an isolated pocket up to a foot deep in areas that were snow covered prior to the Thursday's storm cycle. Avalanches are unlikely in terrain where the recent snow fell onto bare ground.
