Tuesday Night: Cloudy with new snow 5-10 cm. Ridgetop winds light from the West and alpine temperatures near -7. Freezing levels at valley bottom.Wednesday: Mainly cloudy with sunny breaks and isolated flurries. Ridgetop winds moderate from the northwest and alpine temperatures near -6. Freezing levels 1300 m. Thursday: Cloudy with isolated flurries. Ridgetop winds moderate from the West and freezing levels near 700 m. Friday: Mainly cloudy. Ridgetop winds light from the southwest and alpine temperatures near -6. Freezing levels rise to 1100 m.

On Monday, numerous natural and skier-triggered storm slab avalanches size 1 to 2 were reported. In the alpine wind slabs on N-NE aspects also remain reactive up to size 2. Most of these avalanches were running on the newly buried weak layer, especially between 1500 to 1800 m where surface hoar was most prevalent. Natural and human triggered avalanches will likely continue as the weak layer remains reactive.

Another 5-10 cm of new snow brings a total of 20-35 cm above a layer of large surface hoar crystals and sun crust. This slab may show enhanced reactivity between 1500 m-1800 m where the surface hoar is well preserved and on solar aspects at most elevations where there is a buried sun crust. Isolated pockets of reactive wind slab exist on leeward slopes in the alpine. The middle and lower portions of the snowpack are generally well-settled and strong.
