Wind slabs may remain triggerable on lee slopes at upper elevations.
A persistent weak layer remains a concern in the region.
The persistent layer of large surface hoar/ facets/ crust continues to be a concern in some areas. There is uncertainity around how reactive this layer remains.
10 to 25 cm of recent snow combined with strong southwesterly winds built wind slabs on lee slopes. These wind slabs may need another day or two to bond.
Friday
Widespread wet loose sluffing to size 1.5 was observed on sunny slopes, some of which triggered small slabs.
Thursday
Explosives triggered size 3 and 3.5 slabs near Sliding Mountain in the northeastern part of the region. Numerous size 2 to 2.5 wet loose avalanches were also observed across the entire region.
Wednesday
A widespread natural persistent slab avalanche cycle up to size 2.5 occurred. A few cornice falls were also reported.
10 to 25 cm of recent snow is covering a melt-freeze crust that exists up to around 1900 m and on sunny aspects. Some of the new snow may have fallen as rain at lower elevations. Strong southwesterly winds have built wind slabs on lee north and easterly slopes.
The late January persistent weak layer, consisting of surface hoar/facets/crust, may be found buried 30 to 60 cm. This layer remains a concern, particularly in the southern parts of the region.
The mid and lower snowpack is well settled.
