Avalanche Problems

Wind Slabs

Moderate Southwest winds continue to build windslabs and cornices on Northerly aspects. Recent avalanches have started from rock bluffs or cornice failures and have triggered deeper weak layers.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Persistent Slabs

The buried surface hoar layer remains a concern in areas that have not recently avalanched. Whumphing was experienced in North aspect, open shaded glades below treeline today showing that this layer can still be reactive to light loads.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 4

Loose Wet

Expected cloud cover should reduce the solar effect on the snowpack. If there are extended sunny periods, expect to see loose snow avalanches originating from steep rock bluffs.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2
