Avalanche Problems

Wind Slabs

Periods of moderate south through south-west winds have formed soft slabs along the immediate lee of alpine features.
Use caution in lee areas. Recent wind loading has created wind slabs.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Loose Dry

Loose dry snow sluffs can be expected in very steep terrain. This could be an issue in steep gullies and terrain traps.
Be aware of party members below you that may be exposed to your sluffs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
