Confidence

The weather pattern is stable

Problems

Deep Persistent Slabs

A large trigger such as a cornice failure or shallow spots for people could initiate the basal facets on steep unsupported NE aspects. Conditions are generally safe yet watch for unstable snow on isolated terrain features.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood

Unlikely

Expected Size

2 - 4

Loose Dry

Light snowfall has buried a surface hoar layer. It is not a concern for large avalanches but will cumulate into a problem as windloading and new snow input occurs. It is found more preserved TL and below as winds flatten it in the alpine.

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

Elevations: All elevations.

Likelihood

Unlikely

Expected Size

1 - 2
