    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.

Confidence

Moderate - Due to the number of field observations

There was a natural avalanche cycle on Sunday. So far this week, no activity has been reported, although there are not many observers out there right now. Small wind slabs are the most likely type of avalanche during over the next few days.

Snowpack Summary

Approximately 30-40 cm new snow now sits on top of a rain crust that formed during the recent wet weather. The crust is reported to be thick (15 cm) below treeline and thin (2 cm) in the alpine. Strong 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.Treeline snow depths are approximately 100 cm throughout the region.
