Snowpack Summary
Around 10 to 20 cm of snow on Wednesday night into Thursday will accumulate onto a variety of surfaces. The snow will fall on wind-affected snow in exposed terrain at higher elevations, soft and faceted snow in shaded and sheltered areas, and a melt-freeze crust on southerly slopes.The middle and lower snowpack is generally well-settled.
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.
