Timing or intensity of solar radiation is uncertain on Sunday

Avalanche Problems

Loose Wet

Spring conditions exist with a strong melt freeze crust that will deteriorate rapidly with warm sunny conditions. Expect loose snow avalanches to size 2 below treeline on steeper slopes by mid-day.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Large triggers such as cornice failure or serac fall can trigger very large avalanches. Recently, 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: Possible

Expected Size: 2 - 4
