Snowpack Summary
The region received 15 to 30 cm of storm snow accumulations on Monday. It covered previously scoured surfaces and old hard wind hammered snow, sun crusts on solar aspects, and sugary facets pretty much everywhere.February's cold weather weakened the upper- and mid-snowpack. In some sheltered areas, 20-50 cm of the snowpack was faceting, or sits on facets (sugary snow),In the south of the region, the lower snowpack is generally strong.
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.
