Avalanche Forecast
Regions: Little Yoho.
Strong wind from the NW have created wind slabs in alpine lee areas. Human triggering is possible in these areas.
Weather Forecast
Subsiding wind, warming temperatures and a clearing trend will contribute to decreasing the danger rating from considerable to moderate over the next few days.
Snowpack Summary
Wind slabs of varying thickness have been developing on NE through SE aspects due to the moderate to strong wind. These wind slabs sit over top of a well settled mid pack and the Nov 6 rain crust. The Nov 6th crusts lies approximately 30cm from the ground.
Avalanche Summary
One size two avalanche was observed high on Bourgeau 8, above the Bourgeau Left ice climb. It is suspected to be a recently developed wind slab from todays wind event. No other avalanches were observed or reported. Photo of avalanche in Bourgeau 8.
Confidence
Wind effect is extremely variable on Monday
Avalanche Problems
Wind Slabs
Strong wind from the NW have created wind slabs in the alpine. These wind slabs vary in thickness between 15 and 30cm.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 3
Deep Persistent Slabs
The Nov 6th crust should still be in the back of your mind. Recent avalanches on this layer combined with uncertain means of triggering make venturing out onto big open slopes a committing choice.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 2 - 3
