Avalanche Problems

Loose Wet

Surface layers are now rain soaked to 1700m. 5 to 15 cm of snow overnight now covers the old wet surface above 1300m.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 3

Wet Slabs

Upper snowpack is now wet and well settled with a series of variable crusts in the top 60 cm. The crusts provide potential failure plains and good bed surfaces for avalanches Above 1300 m 5- 30cm of storm snow is sitting on the surface.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Wind Slabs

Strong southerly winds in the alpine in the last 48 hours have created windslabs behind terrain features.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3
