Recent snow and wind have developed fresh wind slabs. These will be reactive to riders, especially near alpine ridges and cross-loaded features.
Different elevations and aspects hold different conditions.
Use caution around ridge crests and rollovers where human-triggered wind slab is possible.

No new avalanches were reported; however, limited visibility restricted field observations.
If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.
10 to 20 cm of new snow is found above 1300 m. This overlies a variety of surfaces, including a breakable 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.
