    Storm slabs are primarily a concern in southern parts of the region that received more snow. In the north, isolated wind slabs are the main problem.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

Preliminary reports from Saturday are limited to small loose dry avalanches in steep terrain.On Friday, a size 1.5 wind slab was remotely triggered as a skier approached a steep south-facing slope north of Pemberton. The slab was 10-40 cm deep and had recently been loaded by north winds.On Thursday, a skier triggered slab avalanche was reported in the Duffey area on northwest aspect at 1900 m (see MIN report here).

Snowpack Summary

Friday's storm delivered 10-15 cm in northern parts of the region and 15-25 cm in southern parts of the region. Deeper deposits may be found in wind-affected alpine terrain. Recent snow may sit above hard wind slabs or sun crusts. A weak layer above a crust can be found roughly 20-30 cm deep at treeline and below treeline elevations, and has produced some small slabs with low destructive potential on isolated features. The remainder of the snowpack is generally well-settled.
