Avalanche Problems

Storm Slabs

Moderate amounts of dense snow have added to storm slab conditions. Additional moderate precipitation and rising freezing levels forecast today will elevate avalanche hazard to HIGH.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 3

Wind Slabs

Moderate wind speed values from the S early this morning have caused wind loading on to leeward terrain. This overlies wind slabs created earlier in the storm period. Expect these to be sensitive to human triggering.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 4
