Avalanche Summary
A skier triggered a small hard slab on Wednesday and was knocked off his feet. Glide slabs have been releasing in steep smooth rocky terrain. Otherwise, there has been little recent avalanche activity.
Snowpack Summary
Wind slabs overlie a generally settled snowpack, with no significant weak layers reported in the upper or mid snowpack. Current surfaces include surface hoar, sun crusts and facets. These may provide a weak interface with forecast snowfall. Near the base of the snowpack, a crust/facet layer appears to be inactive. However, it still produces sudden shears in snowpack tests in isolated areas, especially in the northern part of the region. Although unlikely, triggering an avalanche on this layer is possible from thin snowpack areas or with a very heavy trigger.
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.
