Regions

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

Wind slabs may persist in steep terrain at higher elevations, while the lower elevation snowpack remains shallow with plenty of hidden hazards.

Confidence

Moderate

Avalanche Summary

No new avalanche activity has been reported since Monday. However, field observations remain very limited.

Please consider sharing your observations with the MIN.

Snowpack Summary

Strong northerly winds Thursday night into Friday morning have redistributed the snow in the alpine, creating pockets of deeper, stiffer snow in exposed terrain. In more sheltered areas near treeline and below, the snow surface remains mostly soft, dry, and undisturbed.

A firm crust that formed in early November is widespread across alpine and upper treeline terrain, sitting 30 to over 100 cm below the surface. Observations indicate weak faceted grains are developing above and below this crust in some areas.

Overall snow depths range from 50 to 150 cm at treeline and above, with coverage dropping off significantly at lower elevations.

Weather Summary

Friday Night

Mostly clear skies. 10 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Saturday

Mostly sunny. Trace of snow at treeline in areas. 10 km/h north ridgetop wind. Treeline temperature -3 °C.

Sunday

Mostly sunny. 10 km/h west ridgetop wind. Treeline temperature -4 °C.

Monday

Mix of sun and clouds. 1 to 5 cm of snow at treeline. 10 km/h west ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • If it's deep enough to ride, it's deep enough to slide (avalanche).
  • Be cautious of buried obstacles, especially below treeline.

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.
