Regions

Northwest Inland, Kitimat, Nass, Rupert, Seven Sisters, Shames, Howson.

Recent strong winds have built wind slabs.

Avoid leeward features where slabs are likely most reactive.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

A large natural avalanche cycle occurred on Tuesday and Wednesday. With many large (size 2-3) storm slab avalanches.

No new avalanches have been reported so far on Thursday.

Snowpack Summary

Up to 100 cm of recent storm snow has fallen at higher elevations, accompanied by strong southwest wind. Reports suggest a surface crust extends up to 1400 m.

Recent storm snow fell on a layer of small facets and, in places, surface hoar. This measn wind slabs are taking longer to heal than normal.

Weather Summary

Thursday Night
Partly cloudy. 10 km/h west ridgetop wind. Treeline temperature -5 °C.

Friday
Mix of sun and clouds. 10 km/h northwest ridgetop wind. Treeline temperature -7 °C.

Saturday
Mix of sun and clouds. 10 km/h south ridgetop wind. Treeline temperature -8 °C.

Sunday
Mix of sun and clouds. 10 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind-affected terrain.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Avoid slopes that sound hollow or drum-like.

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.
