Regions: Glacier.

Heavy over light snow is being deposited under the influence of strong SW'ly winds. Numerous size 3 natural avalanches have already occurred this morning, running across the valley.

Avalanche Problems

Storm Slabs

A cold front yesterday deposited 10cm of low density snow, which sluffed easily on steep slopes. Overnight, a warm front buried this layer with 35cm of dense, cohesive snow. Moderate southerly winds will have tightened the storm slab further.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 4

Wind Slabs

Moderate to strong S-SW winds have prevailed during recent storms resulting in a series windslabs on exposed terrain. New windslabs are forming, and old ones have been buried. Major drifting and crossloading has been observed.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Cornices

A series of storms have provided lots of snow for transport by sustained southerly winds. Cornices are getting very large, and when they fail will provide large triggers capable of triggering deep layers and large avalanches.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 3 - 4
