Snowpack Summary
Variable hard surfaces that developed during the recent dry spell have been buried by 10-15 cms of new snow. A weak layer of surface hoar or near surface facets was reported on the surface before being buried. Incremental snow falls are expected to continue to build a new storm slab above these weak layers and sliding surfaces.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
