Avoid steep, open terrain features where wind slabs may be lingering. Use ridges or ribs to descend to a lower line that avoids a wind-loaded entry point.

Confidence

High

Avalanche Summary

No new avalanches have been reported. Wind slabs may linger directly lee of ridges and high points at alpine and treeline elevations.

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

Snowpack Summary

Strong to extreme winds continue to build isolated, hard wind slabs at alpine and treeline elevations. Above 2100 m these wind slabs are building over wind-affected surfaces, below this a melt-freeze crust formed in mid-January.

The mid-snowpack continues to settle and is well consolidated. Facets exist near the base of the snowpack. Total snowpack depth ranges between 100 cm to 200 cm in wind-loaded areas.
