Lo esencial

Continually assess conditions as you move through terrain

Strong southerly winds may form reactive wind slabs on leeward slopes at treeline and above.

    Ongoing southerly winds will continue to impact snow in open terrain. Investigate for wind slab around ridges or lee features.

Avalanche Summary

No recent slab avalanches have been reported in the region.

Observations have been limited. Please consider sharing your observations through the Mountain Information Network.

Snowpack Summary

By 4 pm on the 24th  up to 15 cm of new snow may have fallen. This new snow will fall on an already heavily wind affected upper pack in the alpine and at treeline.

The crust from early December is now buried 20 to 40 cm. In some areas, large surface hoar crystals are found at this interface. We are trying to track this surface hoard distribution across the region - most recently, the layer was reactive to skiers in the Ningunsaw area.

Terrain and Travel Advice

  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
