Kernpunkte

Assess for wind slab in steep alpine terrain before committing.

Observations indicate that wind slabs are likely bonded to the underlying crust but this may not be the case everywhere.

    Wind slabs could still be triggered by riders in steep alpine terrain.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

Our field team observed a size 1 wind slab avalanche on an east facing alpine feature. This avalanche released naturally on Wednesday. We suspect that more wind slab activity has occurred this week but visibility has been challenging at times.

Snowpack Summary

Previous storm snow and strong wind has resulted in a variable upper snowpack depending on aspect. On north and east aspects up to 100 cm of dense snow overlies a thick crust from the middle of March. On south and west aspects this crust is on or near the surface. In sheltered features 30 to 40 cm of snow overlies the mid March crust, the snowpack below this layer is well settled and strong.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Closely monitor how the new snow is bonding to the crust.
