Weather Forecast

Monday:Expect cloudy skies with a chance of flurries. Winds should be light and southerly and alpine temperatures should reach -5.Tuesday & Wednesday: Expect precip to build as waves of unsettled weather enter the region. 30-50cm are possible. Southerly winds continue, with occasional gusts and temperatures should reach -5 each afternoon.

Avalanche Summary

Isolated loose wet sluffs have been reported.

Snowpack Summary

Isolated, stubborn wind slabs can be found behind ridges, ribs and on lee slopes (NW-NE). Sun crusts can be found on South and West facing terrain. The upper snowpack is showing continued settlement and gaining strength. Down 20-50 cm sits a persistent interface comprising of crusts, facets and surface hoar crystals. Recently, this layer has been reactive in very isolated, sheltered areas at treeline and below where surface hoar remains preserved. The mid pack is generally well settled with the average snowpack depth at treeline around 180 cm.

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.
