With recent warm alpine temperatures natural avalanches to size 2.5 were reported on steep solar aspects. In a couple of cases, avalanche activity occurred as a wet slab and ran to ground.

A dusting of snow now overlies a variety of old surfaces including stubborn wind slabs in exposed upper elevation terrain, well developed surface hoar in sheltered terrain and a crust on south aspects.The recent prolonged warm temperatures formed a strong and supportive midpack. Closer to the ground, the two weak layers we've been worried about thus far this season (the late November surface hoar, and a crust/facet combo from October) are still there. While the increased strength of the overlying slab has made these layers have become increasingly unlikely to trigger, large and destructive avalanches are still possible with the right input such as a cornice fall or a heavy load over a thin spot in steep terrain.
