Strong winds and flurries will build fresh slabs.If you see blowing snow, watch out for slabs in leeward terrain.

Avalanche Summary

On Tuesday, explosives triggered several thin wind slabs up to size 2 in open areas above treeline. In the Nigunsaw area, a skier triggered a 35 cm thick slab on a steep roll, failing on large surface hoar on a crust. Evidence of older avalanches to size 2, 20 to 30 cm deep were also reported, failing on either surface hoar or a crust.

Snowpack Summary

Up to 15 cm of fresh flurries covers 20 to 30 cm older, wind-affected snow.

The crust from early December is now buried 20 to 40 cm. In some areas, large surface hoar crystals are found at this interface. Most recently, the layer was reactive to skiers in the Ningunsaw area.

Below, the lower snowpack has no layers of concern.

Weather Summary

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.

Avalanche Problems

Wind Slabs

Thin wind slabs may quickly form with strong winds and flurries. If you see blowing snow, expect to find wind slabs in lee-ward terrain.

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