In sintesi

Good skiing may still exist in sheltered areas near Cameron Lake. The wind is expected to increase Tuesday evening - this will likely form sensitive wind slabs in the alpine and at treeline. Once this happens, stay away from steep lee slopes and change your terrain use to lower angle and wind sheltered areas.
