Snowpack Summary
New snow is landing on a medley of snow surfaces includes hard and soft wind slabs, scoured slopes, blue ice, thin melt-freeze crusts and surface hoar. New snow may bond poorly to some of these surfaces, especially where surface hoar sits on a hard crust. Two persistent weaknesses (comprising surface hoar and facets) buried in the upper snowpack give moderate to hard, sudden results in snowpack tests. The mid and lower snowpack is generally well settled and strong, although basal facets remain a concern in the north of the region.
Problems
Storm Slabs
Incoming snow may bond poorly to old surfaces. New wind slabs are also likely to develop during the storm.
Avoid freshly wind loaded features.>Be cautious of sluffing in steep terrain.>
