    Small wind slabs are possible in steep terrain behind ridge lines. On steep slopes, the new snow may not bond well to the underlying crust.

Avalanche Summary

Little activity has been reported lately, although there are not many observers out there right now. Small wind slabs are the most likely type of avalanche over the next few days.

Snowpack Summary

Approximately 30-50 cm of new snow now sits on top of a rain crust that formed during the wet weather in late November. The crust is reported to be thick (15 cm) below treeline and thin (2 cm) in the alpine. Southerly winds have blown snow around in exposed areas creating drifts and scoured areas. Stubborn wind slabs have formed near ridge crests and lee features.Tree line snow depths are approximately 110 cm throughout the region.
