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 crusts exist on south-facing slopes. In general, all the cold weather is weakening the upper- and mid-snowpack. In some sheltered areas, 20-50 cm of previous snow is either faceting or sits on facets (sugary snow), and even possibly surface hoar (feathery crystals).In the south of the region, the lower snowpack is generally strong.

Problems

Wind Slabs

With forecast new snow expect some new wind slab development. Previous strong wind from a variety of directions formed widespread pockets of wind slabs on all aspects.

Seek out sheltered areas where the snow is unaffected by wind.Watch for patterns of wind loading as you venture into wind affected terrain.Watch for signs of instability such as whumpfing, or cracking.

Aspects: North, North East, East, South East, South, North West.
