Recent Avalanches

A remotely triggered avalanche occurred yesterday, 12/28, on the SE face of Hatch Peak. See more details in the observation HERE.

A small, human triggered wind slab avalanche was reported on Sunday 12/23. See observations HERE.

No other avalanches have been reported.

Additional Concern

Problems: PERSISTENT SLAB, WIND SLAB, LOOSE DRY

Expect heavy wind loading to trigger natural activity, and activate weak layers in the snowpack today through tomorrow.

Now is a good time to avoid avalanche terrain. Avoid terrain traps, see yesterday’s advisory for more details, such as recent avalanches.
