Confidence

Intensity of incoming weather systems is uncertain

Avalanche Problems

Loose Wet

If freezing levels remain at mountain top elevations, expect to see avalanches where rainfall has soaked into the upper layers of the snowpack.

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

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Wind Slabs

Sunday's rain soaked into the recent storm snow adding more load to windslabs. This may contribute to natural and skier initiated avalanches at all elevations.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Warm temperatures and rain may contribute to cornice fall which could overload these weak layers contributing to full depth avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
