Avalanche 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.

Aspects: North, North East, East, South East, South, South West.
