Highlights

The chance for natural avalanche activity has mostly diminished, and the likelihood of human triggered slides is on a decreasing trend. However, the potential consequences of being caught in a large wind slab will keep the avalanche hazard elevated above 7,500 feet. Although unlikely, the possibility of deeper slabs failing on or stepping down to October snow might remain. This scenario warrants a conservative approach to terrain selection. Don’t let sunshine and fresh snow cloud your judgement when choosing your travel plans. Precipitation was mainly in the form of rain below 7,500 feet, and the shallow snowpack is mostly stable.

    Around two feet of snow containing over two inches of snow water equivalent has fallen since Wednesday evening. Strong southwesterly to northwesterly ridgetop winds have accompanied this snowfall forming dense wind slabs on leeward slopes. In steep, wind-loaded avalanche terrain above 7,500 feet, skiers and riders could trigger these slabs ranging in depth from six to 18 inches if failures occur on density breaks within the new snow. In heavily wind loaded terrain near upper elevation ridgelines, these slabs could be up to four feet deep if a slide involves all of the recent snowfall.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Flow aloft will veer to the northwest bringing cold, dry air to the region. Overnight, snowfall will diminish and skies will begin to clear. By Saturday morning, mountain temperatures will dip into the single digits before rising into the mid to upper teens during the day. Westerly to northwesterly ridgetop winds will range from 20 to 35 miles per hour.While the chance for natural activity will mostly diminish, and the likelihood of human triggered slides is on a decreasing trend, the consequences of wind slabs up to four feet deep will keep the avalanche hazard CONSIDERABLE at the higher elevations. Although unlikely, the potential of slides going down to October snow might remain. Don’t let sunshine and fresh snow impair your judgement. Heightened avalanche conditions will continue, and a cautious approach to terrain selection is warranted. Give the snowpack some time to adjust to the loading event over the past couple of days.
