    A weak layer of buried facets near the ground continues to be a concern in the north of the region. Try to get local knowledge if you are traveling to new areas.

Avalanche Summary

No new avalanches to report.

Snowpack Summary

In general the snowpack seems shallower and more faceted in the northern part of the region, and deeper with more wind slab problems in the south. At 1300m on an east aspect in the Shames area the height of snow is about 190cm. Light amounts of new snow now overlie a variety of old surfaces which include surface hoar in sheltered locations, and wind-affected snow at upper elevations. Depending on your location, you may find a facet/crust combo or surface hoar about 50cm below the surface. Reports suggest these layers are gaining strength; however, they may be worth keeping an eye on with forecast storm loading over the next few days. Deeper early December facetted crystals were also found to be rounding and gaining strength in this area.
