Monday's forecast shows mainly cloudy with light flurries and freezing level around 1600m. Alpine temperature around -6c and 30km/h wind.

Avalanche Summary

Numerous loose dry avalanches up to size 1.5 observed in past 48hrs on the Nov 12 crust mostly on E aspects in the Alpine.

Snowpack Summary

20cm of low density snow is overlying Nov 12th temperature crust. Isolated wind slabs observed in the Alpine along ridge lines and cross loaded gullies. There is an average of 50-60cm at 2200m and tapers quickly with elevation.

Avalanche Problems

Wind Slabs

Wind slabs overlying the Nov 12 crust may be sensitive to human triggering. Use caution around ridge lines, gullies and cross-loaded terrain.

Carry avalanche safety equipment on ice climbs in avalanche terrain.Be careful with wind loaded pockets while approaching and climbing ice routes.Caution in lee and cross-loaded terrain near ridge crests.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
