Problems

Cornices

Recent snow and wind have have made large cornices even bigger and more sensitive.

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

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

3 - 7

Wind Slabs

Recent new snow and moderate southerly winds continue to build windslabs.

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

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

1 - 5

Deep Persistent Slabs

Persistent weaknesses are buried about 150-200 cm below the surface. Avalanche activity on this interface has become less frequent, but large triggers like cornice fall may release a large avalanche.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely

Expected Size

3 - 7
