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 since then.

Snowpack Summary

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

Up to 100 cm of snow fell earlier in the week at higher elevations, accompanied by strong southwest wind. Reports suggest a surface crust extends up to 1400 m.

The mid and lower snowpack is well settled with no layers of concern.

Weather Summary

Friday Night
Mostly clear skies. Calm wind. Treeline temperature -7 °C.

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

Sunday
Mostly sunny. 10 km/h west ridgetop wind. Treeline temperature -9 °C.

Monday
Mix of sun and clouds. 1 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -10 °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.
