Snowfall and strong winds are forming new storm slabs and wind slabs.
Human triggered avalanches are likely on lee aspect terrain features.
Strong westerly winds will transport new snow, forming new wind slabs. Avoid areas just below ridgetop, where deep drifts and large pillows of snow have formed.
Numerous small to large avalanches ( up to size 3) where observed over the past week. These avalanche where primarily on north aspect terrain and where triggered by either ongoing wind loading or during a period of rapid warming.
10 to 15 cm of new snow overlies a thin crust that was buried on Friday. Below this 20 to 50 cm of mostly light snow sits above a 20 cm thick crust that was formed after last weeks warming temperatures and rainfall.
90 to 120 cm deep, on steep southeast through southwest slopes, a crust with weak, sugary facets on top has been observed. This layer is still a concern, but is currently dormant.
The mid and lower snowpack is well settled, with no layers of concern.
