Avalanche Summary

A size 1.5 windslab was triggered on a lee slope in the north of the region on Tuesday. It released on the weaker facets below the wind affected snow. A few thin (size 1) wind slabs were observed on Saturday, as well as numerous loose dry avalanches.

Snowpack Summary

Open areas at upper elevations are likely wind affected, while pockets of soft snow can be found in sheltered and shaded areas.Sun crust are likely found on south-facing slopes. In some sheltered areas, 20-50 cm of recent snow may sit on facets (sugary snow) or surface hoar (feathery crystals), but no recent activity has been reported on these layers.In the south of the region, the lower snowpack is generally strong.

Problems

Wind Slabs

Strong wind from a variety of directions formed widespread pockets of wind slabs on all aspects.

Watch for patterns of wind loading as you venture into wind affected terrain.Seek out sheltered areas where the snow is unaffected by wind.Whumpfing, shooting cracks and recent avalanches are all strong inicators of unstable snowpack.

Aspects: All aspects.
