Avalanche Summary
Large persistent slab avalanches continue to occur sporadically on the weak layer buried in early December. This problem is starting to improve but deserves patience and continued vigilance.
Snowpack Summary
Expect to find 20 to 50 cm of settling snow in sheltered areas and wind slabs on lee slopes. On sun-affected slopes, soft snow covers a melt-freeze crust.
A concerning layer of facets, crusts, and/or surface hoar is buried 60 to 110 cm. It will most likely be a problem on north through east aspects between 1700 and 2300 m.
Treeline snow depths range from 100 to 180 cm.
