The winter permit system is NOT yet in effect. Travel conditions are poor below treeline, but good skiing can be found in the alpine. Expect loose sluffing of the new low density storm snow.

Problems

Wind Slabs

50cm of storm snow overlies a crust. Strong south winds early last week created windslabs on exposed lee slopes. Winds shifted to northerly, reverse loading many slopes. Watch for pockets of windslab in the alpine on exposed slopes.

Be cautious as you transition into wind affected terrain.
