Conditions vary with elevation, aspect, and wind exposure.
Small reactive wind slabs will develop at upper elevations as snow accumulates.
New snow and wind will develop fresh wind slabs. These will be reactive to riders, especially near alpine ridges and cross-loaded features.
No new avalanches were reported.
Wednesday, numerous natural, wet loose avalanches (up to size 1) were observed. These avalanches occurred in steep, rocky south-facing slopes.
If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.
Light amounts of new snow are expected for Friday night and Saturday. This new snow will overlie a variety of surfaces, including a crust on south-facing aspects, wind-affected snow on north-facing terrain, and surface hoar on sheltered features.
The mid-December crust is 90 to 150 cm deep, except on wind-scoured alpine features, where it could be on the surface. This crust is 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.
