Continue to assess for signs of instability. Wind slabs may remain a lingering concern at higher elevations.

Summary

Confidence

High

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.
