Not much is changing in the snowpack at the moment, but pockets of wind slab may still be triggered in steep and unsupported terrain. Early season hazards are prevalent.

Summary

Confidence

Moderate -

Weather Forecast

Thursday will be mainly cloudy with isolated flurries. Temperatures in the Alpine will reach a high of -8 °C and ridge top winds will be out of the southwest at 50 km/h. Friday could see light accumulations of snow in the 5 - 10cm range.

Avalanche Summary

No new avalanche activity observed or reported in past 72hrs.

Snowpack Summary

Up to 2cm of new snow in the past 24hrs has done little to change the snowpack. Pockets of wind slab are present in lee and cross-loaded features in the Alpine. The Nov 12th crust is buried 20 to 25cm at Treeline elevations and is still supportive to skier traffic.

Problems

Wind Slabs

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