Snowpack Summary
Approximately 10 to 15 cm of new snow has buried a widespread crust. Strong winds earlier this week have scoured surfaces down to the crust in most windward-facing terrain while forming deeper deposits of snow in lee terrain.
Previously problematic layers deeper in the snowpack appear to have bonded and strengthened, however, there is a low likelihood that they could remain a risk in steep, north-facing, alpine terrain.

Terrain and Travel Advice
- Start with conservative lines and watch for clues of instability.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Brief periods of sun could quickly initiate natural avalanche activity.
Problems
