Regions

South Coast, Powell River, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Danger is Low due to a strong surface crust. Small wind slabs may be found in alpine terrain.

Confidence

High

Avalanche Summary

No recent avalanches have been observed in the North Shore mountains.

A small (size 1) wind slab was triggered by a skier near Powell River on Wednesday (see photo).

Snowpack Summary

A surface crust exists to the top of the North Shore mountains, while higher elevations in other parts of the region have heavily wind-affected surfaces.

Conditions remain rugged at lower elevations.

Terrain and Travel Advice

  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
  • Watch for areas of hard wind slab on alpine features.

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.
