Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Ongoing snowfall and wind continues to build windslabs.

Travel cautiously, as the snowpack is shallow and hides thinly buried hazards.

Confidence

Low

Avalanche Summary

No avalanches have been reported. However, observations are limited.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

Up to 15 cm of new snow overlies weak surface hoar and facets and may not be bonding well. Steep south-to-west slopes now have a thin sun crust, while wind-exposed features are hard and smooth.

A firm crust that formed in early November can be found 30 to 100 cm down at alpine and treeline elevations. Weak, sugary facets have been spotted above and below the crust. This layer isn't currently a concern, but with the forecast precipitation and snowfall it may be possible to produce large avalanches. Expect to find 50 to 150 cm of snow, treeline and above, with snowpack depth decreasing rapidly below 1600 m.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • 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.
