Avalanche Summary

No new avalanches have been reported. On Thursday, some small avalanches were triggered by ski cutting on small wind loaded pockets in the Hankin area.

Snowpack Summary

Surface snow has been affected by recent winds from a variety of directions. The degree of wind affect varies throughout the region, with the most dramatic winds associated with outflow conditions in the western parts of the region near coastal inlets. Sheltered areas may still have 10 to 30 cm of powder from previous storms. Roughly 20 cm below the surface, a highly variable weak layer exists. It comprises of facets in cold areas, crusts on solar aspects, and in protected areas below 1500 m, feathery surface hoar. In most places, insufficient snow has fallen above this layer for it to be reactive, but it should be considered in deep snow areas, or where the wind has blown additional snow over the top of it.
