Avalanche Summary
Looking ahead, 5 to 15 cm of snow will fall with moderate north winds which could form fresh, reactive wind slabs on lee slopes.
The arctic front on Wednesday resulted in a cycle of natural wind slab avalanches, up to 45 cm deep. These wind slabs on south aspects could remain reactive to human triggering.
Snowpack Summary
5 to 15 cm of new snow falls on mostly firm, wind-affected surfaces. In a few sheltered areas, soft snow was reported to remain. This new snow comes initially with strong southwest and then moderate north winds, so new wind slabs may form on a variety of aspects.
A layer of surface hoar that formed on Christmas Eve may be found 50 cm deep, but recent observations suggest it has bonded.
