Avalanche Problems

Loose Wet

Cooler temps in the morning followed by rising freezing levels and light precipitation. Watch for moist surface snow especially around rocks and trees.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Wet Slabs

The upper snowpack is now moist and isothermal to 2000m with a series of crusts in the top 90 cm. The crusts provide potential failure plains and good bed surfaces for avalanches. Recent large avalanches have been failing to the ground.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Cornices

There is good potential for cornice falls to produce large avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
