Use caution in wind effected terrain, wind slab over facets, surface hoar or a crust remains the primary concern.
Wind slabs could remain reactive to rider traffic as a result of the surface hoar, facets and crust they have formed over. Wind slabs over surface hoar could be remotely triggered.
No new avalanches have been reported in the past couple days. That being said over the past week we have seen a pattern of human and remotely triggered size 1 to 1.5 wind slab avalanches with a few being up to size 2. These avalanches have generally failed on a combination of facets, surface hoar and a crust.
Surface conditions are highly variable. Wind effect can be found on all exposed slopes. A new crust exists on the surface at lower elevations and likely up to mountain tops on south aspects. In sheltered terrain soft snow can still be found and may have surface hoar forming above it. In the afternoon the snow surface could become moist at lower elevations.
15 to 30 cm of snow sits above a widespread crust. Many areas have reported a weak surface hoar layer above this crust, which is problematic in areas where wind has formed a slab above the layer.
Snowpack depths decrease rapidly below treeline.
