Snowpack Summary

A dusting of new snow in the south of the region overlies a snow surface that has been heavily affected by strong wind. You will likely find a variety of hard slabs, wind-pressed snow, sastrugi, sugary faceted snow, and melt-freeze crust where the wind has scoured down to it. In sheltered areas below treeline, you may still find pockets of soft, faceted snow.In the south of the region, the remainder of the snowpack is well-settled. In the north of the region, 50 to 100 cm of snow may overly two weak layers of feathery surface hoar crystals or faceted grains.

Avalanche Problems

Wind Slabs

Continuous strong wind has affected the snow surface. Isolated wind slabs may exist in steep terrain features.
Be careful around wind loaded pockets near ridge crests and roll-overs.Watch for patterns of wind loading if you venture into wind affected terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible
