Around 15 cm of new snow fell on a weak layer of feathery surface hoar, 5 to 10 mm in size. The new snow will likely not bond well to this layer, allowing for snow to move easily, fast, and far. Snow amounts will be deepest in the lees of terrain features immediately adjacent to ridges.Below 1800 m, storm snow from last weekend may not be bonding well to an underlying crust
(see here). In other areas, reports indicate that the recent snow is bonding well.Another weak layer of sugary facets and surface hoar lies around 150 to 200 cm deep in the snowpack. There hasn't been reports of avalanches on this layer for over a week. That being said, this layer may still exist in isolated areas around treeline in some portions of the region.At the base of the snowpack, weak and sugary facets are found below an early-season melt-freeze crust. This weak layer has been the culprit for sporadic, very large avalanches in alpine terrain in the past few weeks. The avalanches have occurred in areas where the ground roughness is very smooth, for example glaciers, firn, and shale/rock slab slopes. An avalanche could be triggered in this layer with a very large trigger, such as a cornice fall.
