Highlights

Stormy weather will continue Sunday.  Higher elevations will get significant snowfall, and Wind Slab avalanches are expected on North and East facing slopes at and above treeline.  Elevations below 6,800 ft. will get a mix of snow and rain, and conditions will mimic Saturday's conditions.

    Stormy weather nearly always means that we see Wind Slab avalanches in alpine terrain and at treeline where the wind is free to move snow onto sheltered lee slopes.  The Wind Slab avalanche problem on Sunday will be tied directly to the snow level which is forecast at 6,800 ft.  This means that open bowls and slopes at treeline might sneak through with all snow and Wind Slab avalanches are possible.  Watch for where the wind is blowing the snow, and evaluate how much new snow has accumulated on these lee slopes (it may be easy if the crust from Friday and Saturday is present).

     

Avalanche Discussion

Observers have been finding 90-120 cm. of snow throughout most of our ski terrain.  Today it rained to about as high as anyone ventured out.  This morning I was breaking trail through a thin rain crust over last weeks pow.  We haven't seen evidence of any persistent weak layers in our snowpack.
