Snowpack Summary
New snow is expected on Wednesday at higher elevations, which will fall with southwest wind. The precipitation will fall onto a hard melt-freeze crust on all aspects and elevations except for north slopes above 2000 m, where it will fall onto dry snow. Snow is disappearing rapidly at lower elevations.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
