Expect avalanche danger to increase through the day as new snow accumulates.
Use conservative route selection and resist venturing into complex terrain.
Ongoing snowfalls and wind will keep developing fresh storm slabs. These will be reactive to riders, especially near alpine ridges and cross-loaded features.
No new avalanches were reported.
If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.
Up to 15 cm of new snow has fallen at treeline on Saturday morning. This new snow will overlie a variety of surfaces, including a crust on south-facing aspects, wind-affected snow on north-facing terrain above 2100 m, and surface hoar on isolated, sheltered features.
The mid-December crust is 100 to 200 cm deep and well-bonded to the snow above. Above 2200 m, this crust is absent and a layer of facets and a crust from November is found at the base of the snowpack. These layers are not currently a concern.
