Avalanche Problems

Loose Dry

A surface hoar layer is buried a few cm's down. Flurries and winds are forecast now until Wednesday which will incrementally bury it deeper. The danger rating will increase once critical load achieved. Monitor this situation and natural activity.

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

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 1 - 2

Deep Persistent Slabs

Conditions are generally stable but be cognisant of slopes threatened by large triggers such as overhead cornices on steep unsupported alpine features.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 2 - 4
