Several small wind slabs were triggered by skiers near ridge crest on Monday. Incoming weather is expected to create new storm slabs.

New snow, wind and warming are expected to build new storm slabs. Cornices are also likely to grow larger. The new snow will bury old wind slabs on a variety of slopes at alpine and treeline elevations. At treeline and below, two weak layers exist in the upper 2 m of the snowpack. These layers consist of surface hoar (feathery crystals) in more sheltered areas and a crust on solar aspects and on all aspects below 1500m.In the lower snowpack, a crust/facet (sugar snow) layer is now over 2 m deep. There have been no recent reports of avalanches on this layer, but it may still be reactive to heavy loads (such as a cornice fall) in isolated areas.
