Regions

Northwest Coastal, Kitimat, Nass, Rupert, Seven Sisters, Shames, Stewart, Howson.

Continuously assess conditions as you move through terrain.

Wind slabs can be found up high, early season hazards are just below the surface at lower elevations.

Confidence

Low

Avalanche Summary

A small skier triggered slab avalanche was reported near Shames on Wednesday. This avalanche was on a steep slope on a south aspect at treeline.

No other avalanches have been reported in the region over the past few days, but observations are limited.

Please continue to share your observations via the Mountain Information Network.

Snowpack Summary

Recent variable winds have produced wind slabs on all aspects.

A mid-November surface hoar layer is buried 30 to 40 cm deep in sheltered treeline terrain.

Below 1400 m, a 2 to 10 cm rain crust sits 40 to 60 cm down but is not currently a concern.

Above treeline, the snowpack is deeper than average at roughly 200 cm, tapering steadily with elevation to around 30 cm at valley bottom, where many early-season hazards remain just below the surface.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Be cautious of buried obstacles, especially below treeline.
  • Make observations and continually assess conditions as you travel.

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.
