Reactive wind slabs may be forming in more sheltered terrain features from strong wind.
Keep your guard up at all elevations, and avoid wind-loaded features.
Strong to extreme southwest wind will further redistribute any soft snow still available for transport. Expect reactive wind slabs deep in terrain features and in sheltered terrain.
No new avalanches were reported. We suspect that loose avalanche up to size 1 to 1.5 were occuring in steep terrain on Sunday.
On Friday, a few explosive triggered storm slabs up to size 2 were reported in the alpine.
Strong to extreme winds are heavily wind affecting last week's storm snow. Expect newly formed wind slabs deep into the terrain.
The wind affected snow sits on a 3 to 10 cm thick crust on all aspects. The thickness of the crust depends on elevation.
A persistent weak layer of surface hoar and/or crust may be found around 70 to 100 cm down. Human triggered avalanches are unlikely on this layer in areas where a supportive crust exists below the recent snow.
In shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack.
