Confidence
Avalanche Problems
Wind Slabs
Wind slabs exist in many open areas in the alpine. These will be less sensitive to triggering by the weekend due to cooler temperatures, but watch the bond between the wind slabs and the harder surfaces below on Friday.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Cornices
Many cornice collapses over the last week will continue with higher freezing levels. Further East these have triggered basal facets in isolated events.
- Stay well back from cornices.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 2 - 3
Loose Wet
We may see an increase in avalanche activity if the sun stays out for an extended period of time, along with higher freezing levels.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
