Snowpack Summary
Reports suggest there is about 50cm of snow at 1600m in the Duffy Lake area, and about 100cm at the same elevation on the Coquihalla. Terrain below treeline is reported to be mostly below threshold for avalanche activity.Between 15 and 25cm of new snow now overlies a generally well settled snowpack. In exposed high elevation terrain this new snow may exist as a wind slab. Rain at lower elevations has continued to saturate what little snow there is. Closer to the base of the snowpack you may find a few crusts which may have associated facets at higher elevations. Observers are not identifying any of these as cause for concern at this time, although they might be worth exploring.
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.
