Snowpack Summary
There is a lot of variability in the recent storm snow amounts and the amount of wind effect across the region. The Harvey Pass area has seen a lot of wind. Thin stiff wind slabs have formed, and fetch areas have been stripped. The Crossing Creek area has seen less wind and about 20 cms of new snow. It was snowing all day Friday, so we expect the storm snow to continue to accumulate. The storm snow has not been reported to be reacting as a cohesive slab.
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.
