Normal cautions should be sufficient to manage lingering wind slabs in steep terrain near ridgetops.
Older wind slabs across a range of aspects have mostly stabilized. In isolated steep terrain, some slabs formed over weak snow grains sitting on hard crust may still react to a human trigger.
No new avalanches have been reported in the past few days. Operators in the Hope area noted small sluffing of new snow from steep terrain on Wednesday, confined to areas where smooth snow coverage exists.
Light new snow amounts have begun to accumulate over a variety of surfaces including; surface hoar in sheltered terrain, A crust on south aspects and all aspects below treeline and old wind effected surfaces in exposed terrain.
A widespread crust exists 25-40 cm below the surface, and surface hoar has been found above the crust in some parts of the region. Old, likely stubborn wind slabs formed over this layer are a lingering concern.
The remainder of the snowpack is well settled. Conditions remain rugged at lower elevations.
