Kernpunkte

Use caution on north and east aspects in the alpine where new wind slabs could be found

If the sun comes out the likelihood of cornices falling will increase

    New wind slabs will likely have formed by Saturday morning. These slabs will likely be rider triggerable.

    Keep your head up and look for cornices, they could fail during periods of strong solar. Cornices are a hazard on their own but can also trigger wind slabs on the slopes below.

Avalanche Summary

No new avalanches have been reported in the past couple days.

Snowpack Summary

The snowpack is highly variable; on exposed west aspects very little snow remains, on exposed north and east aspects new wind slabs could be found. These wind slabs will overlie a firm and supportive crust.

In sheltered terrain  at 500 m the snowpack is 100 to 130 cm deep. The mid and lower snowpack is strong and bonded.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
