Snowpack Summary
5-15 cm new snow has fallen onto a wind-affected surface in high alpine and a widespread melt-freeze crust elsewhere. In the central and northern parts of the region, this snow may fall onto feathery surface hoar crystals in sheltered terrain at all elevations.In the south of the region, the remainder of the snowpack has been reported as well-settled.Around and north of Hazelton, 40 to 100 cm of snow may overly two weak layers of surface hoar found in sheltered and shaded areas. A weak layer of sugary faceted grains may also exist, approximately 150 to 200 cm deep.
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.
