Avalanche Problems

Loose Wet

Expect the firm melt freeze crust to deteriorate rapidly with the warm rainy conditions which are in the forecast through the weekend. Loose snow avalanches are possible below treeline if we receive heavier than predicted showers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Large triggers such as cornice failure or serac fall can trigger very large avalanches. Recently, an ice fall released a large slab avalanche on a steep north facing glacial slope on Mt Andromeda.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
