Use caution in areas where the snowpack transitions from thick to thin, especially near ridge crests.
Soft snow and good riding can be found in sheltered terrain features.

Avalanche Summary
There have been no new persistent slab avalanches reported in the past 6 days, but uncertainty remains regarding the early December layer mentioned in the snowpack summary.
Snowpack Summary
Previous strong outflow wind has impacted the snow surface in exposed terrain on all aspects and elevations. Ongoing cold temperatures have softened the upper snowpack in sheltered terrain.
A weak layer of facets and a crust from early December is buried 70 to 100 cm deep. This layer exists on all aspects up to 1700 m.
At the highway elevation the snow is 120 cm deep and in the alpine exceeds 200 cm.
Weather Summary
Sunday Night
Mainly clear. 15 to 30 km/h northeast ridgetop wind. Treeline temperature -17 °C.
Monday
Sunny. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -15 °C, potential for strong temperature inversion with a high of -6 °C in the alpine.
Tuesday
Sunny. 10 to 15 km/h southwest ridgetop wind. Treeline temperature -10 °C, potential for inversion with warmer temperatures in the alpine.
Wednesday
Sunny. 10 to 25 km/h northwest ridgetop wind. Treeline temperature -14 °C, potential for inversion with warmer temperatures in the alpine.

Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Be aware of the potential for large avalanches due to a buried crust.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Persistent Slabs
The early December weak layer may still be triggered in shallow, thin-to-thick areas, or with large loads like a cornice fall. Carefully manage your exposure to overhead hazards.
