Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Wind sheltered terrain at higher elevations is likely hold the best riding conditions. Watch for changing conditions in the snow surface as you transition through elevation bands.

Confidence

High

Avalanche Summary

There was a report of a size 1.5 wind slab avalanche at treeline on a north aspect in Manning Park on Saturday.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Wind affected snow can be found at higher elevations, with recent storm totals of 10-20 cm sitting over a crust below 2000 m.

The snowpack below is considered settled. Weaker layers exist but with thick crusts sitting above, triggering avalanches on these layers is unlikely.

Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m.

Weather Summary

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Carefully evaluate steep lines for wind slabs.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
