Snowpack Summary
New snow on Tuesday will fall onto a variety of hard slabs, wind-pressed snow, sastrugi, sugary faceted snow, and melt-freeze crust. In sheltered areas at and below treeline, new snow may fall into pockets of feathery surface hoar crystals and soft, faceted snow.In the south of the region, the remainder of the snowpack is well-settled. In the north of the region, 50 to 100 cm of snow may overly two weak layers of surface hoar or faceted grains.
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.
