Avalanche Forecast

Moderate - Wind effect is extremely variable

Saturday: Mainly cloudy. New snow 5-10 cm accompanied by strong westerly ridgetop winds. Alpine temperatures near -7 and freezing levels 900 m.Sunday: Mix of sun and clouds with isolated flurries. Ridgetop wind strong from the West and freezing levels near 800 m.Monday: Cloudy with new snow 3-8 cm. Ridgetop wind strong from the West. Alpine temperatures near -4 and freezing levels 1200 m.

On Friday, no new observations were reported. I suspect a widespread natural cycle continued up to size 3. Given the weather forecast storm slabs and wind slabs will continue to be reactive throughout the weekend.

Up to 20 cm of new snow brings the recent storm snow up to 35 cm in some locations. Strong easterly winds have redistributed the new snow onto leeward aspects forming thicker slabs. Forecast winds from the southwest will likely build new wind slabs on easterly aspects. The new snow will likely have a poor bond initially to the underlying snow surfaces which consist of surface hoar (buried March 9th and 19th) on northerly aspects in higher elevation bands and firm melt-freeze crusts at treeline and below.In the mid-pack, a surface hoar and crust layer from January is buried around 80 to 140 cm in the southwest of the region. This layer is currently unreactive, however, may have the potential to be triggered from a thin snowpack spot, or with a large trigger like a cornice fall.Sugary facets exist at the bottom of the snowpack in steep, rocky, and shallow snowpack areas.
