Avalanche Summary

Small wind slab avalanches were triggered naturally and by skiers on Tuesday. They were on all aspects and at treeline and alpine elevations. The slabs ranged from 20 to 60 cm deep.

Snowpack Summary

Thursday and Friday's storm may deliver another 10 to 15 cm of snow, which will add to the 5 to 10 cm received on Tuesday. Strong southwest wind during both of these storms will form wind slabs in cross-loaded and lee terrain features in exposed areas. In sheltered areas at and below treeline, this new snow fell onto pockets of feathery surface hoar crystals and soft, faceted snow.In the south of the region, the remainder of the snowpack is well-settled. In the north of the region, around 50 cm of snow may overly a weak layer of surface hoar or faceted grains.
