Regions: Little Yoho.
With another skier remote size 3 today and more field tests at treeline, we have little confidence in the snowpack stability, keep to conservative routes on small features and carefully evaluate consequences if you were to trigger an avalanche. LP
Avalanche Problems
Persistent Slabs
Another skier remote near Lake Louise (photo on the MCR) size 3. They were returning for their 2nd run when they triggered the slope they just skied from the ridge above. They remote triggered a windslab, which triggered the deeper slab.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 2 - 3
Wind Slabs
It's remains possible to trigger this layer, especially in the alpine. Be especially cautious with any windloaded features.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 2 - 3
