Assess for wind slabs in consequential terrain before committing.

High

Avalanche Summary

Small (size 1) isolated pockets of wind slab could be triggered by riders in lee terrain features. Wind slabs may linger directly lee of ridges at high elevations.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Strong to extreme southwest wind continues to build isolated, hard wind slabs in the alpine near ridges. Wind slabs are building over wind-affected surfaces above 2100 m and a melt-freeze crust below.

The middle of the snowpack is consolidated. Weak faceted grains exist near the base of the snowpack.

The average snowpack depth is 120 cm and 200 cm in wind-loaded areas.
