Regions

Sea To Sky, South Coast Inland, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Consider what is below you, as a small avalanche may have high consequences if combined with a terrain trap.

Confidence

Moderate

Avalanche Summary

On Thursday, a few small loose avalanches were reported northwest of Pemberton when the sun hit soft snow on south aspects.

Snowpack Summary

Wind from the north redistributed exposed snow into lee features, forming stiff wind slabs. Sheltered areas have the best riding and less chance of slab formation.

A firm crust that formed in early November can be found 30 to 100 cm deep in the alpine and at treeline. Weak, sugary facets have been spotted above and below the crust.

Expect to find 50 to 150 cm of snow, treeline and above, with snowpack depth decreasing rapidly below 1600 m.

Weather Summary

Saturday Night
Clear skies. 10 km/h east ridgetop wind. Treeline temperature -3 °C.

Sunday
Mostly sunny. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -2 °C.

Monday
Mix of sun and clouds. 2 to 4 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -2 °C. Possible above freezing layer.

Tuesday
Mostly sunny. 1 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Be cautious of buried obstacles, especially below treeline.
  • Carefully evaluate steep lines for wind slabs.

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.
