Kernpunkte

Dangerous avalanche conditions exist. A Winter Storm Warning remains in effect through 11 AM, and rapid loading will continue during this period. The Wyoming Department of Transportation fired their GazExs this morning and had activity in Glory Bowl with debris filling the ditch just uphill of the road. In steep, wind loaded terrain at the mid and upper elevations, skiers and riders are likely to trigger wind slabs ranging in depth from one to three feet. Natural avalanche activity will also be possible. A cautious approach to terrain management along with conservative decision making will be mandatory for safe travel in avalanche terrain. At the lower elevations, backcountry travelers might be able to trigger an isolated pocket of soft slab in very steep terrain.

    Since Thursday morning, up to two inches of snow water equivalent has been added to the snowpack. Strong southwesterly to northwesterly ridgetop winds, abundant snowfall and ample snow available for transport have combined to form small to large wind slabs above 7,500 feet. These slabs are forming on sun crusts, near surface facets and surface hoar. When evaluating the snowpack, be on the lookout for weak faceted snow, and determine how well the new snow is bonding to the underlying sun crusts. Whumphing and shooting cracks should be clear red flag indicators of dangerous conditions.

Avalanche Discussion

Cloud cover will continue to decrease overnight, and any lingering flurries should dissipate by the morning. Skies on Sunday should be mostly sunny. Overnight lows in the mountains will be in the single digits before rising into the mid-teens during the day. Northwesterly ridgetop winds will back to the west and decrease to 5 to 15 miles per hour.The general avalanche hazard is expected to be Considerable above 8,000 feet. Up there, skiers and riders venturing into steep, avalanche prone terrain are likely to trigger recently developed wind slabs ranging in depth from one to three feet. The most problematic areas will be on slopes where faceted snow resides under the recent snowfall. Entering avalanche terrain where these faceted weak layers may be present is rolling the dice. Don’t let blue skies and abundant snowfall cloud your judgement. Dangerous avalanche conditions exist, and the snowpack should be evaluated with a keen eye. Below 8,000 feet, the hazard quickly transitions to Low.
