Avalanche Problems

Loose Wet

This problem will be a concern whenever overnight freezes are minimal or rain or daytime heating issues arise.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 4

Deep Persistent Slabs

"Warm days" are re-awakening some of the deeply buried weak layers at the base. There has been recent activity on this layer. These slides are proving to be very destructive taking out mature timber at the base of there normal runouts.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 4 - 7

Cornices

Mature cornices may provide large triggers to trigger loose wet or deep persistent slabs

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 6
