Regions: Little Yoho.

The majority of this area has a well settled snowpack. We have limited observations in the alpine and whether basal facet layers are present.  Excellent ski conditions and coverage overall.

Weather Forecast

Westerly winds will stay in the moderate to strong range on Saturday. Highs of -5C at valley bottom and -12C in the alpine. 3-5cm expected Saturday and 3-5 on Sunday.

Snowpack Summary

Up to 30cm of snow over the last few days sits over top of a well settled mid-pack. In much of this deeper snowpack region, the lower snow-pack is well settled and displays no significant shears. Shallower snowpack areas will likely have more pronounced basal facets. Isolated wind slabs exist near ridge tops and in lee terrain at alpine elevations.

Avalanche Summary

No natural activity observed. The ski-hills reported small wind-slabs and moderate cornice development (described as fridge sized).

Confidence

Avalanche Problems

Wind Slabs

Small wind-slabs can be expected near ridge-tops and lee terrain in the alpine.

  • Use caution in lee areas. Recent wind loading has created wind slabs.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

The mid and lower snowpack is generally strong in this region. Concern still exists for shallower areas especially in the alpine where basal facets may exist. We have limited alpine observations to know if this is a problem or not.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3
