Regions

Vancouver Island, East Island, North Island, South Island, West Island.

Good skiing can still be had in shaded alpine terrain. Seek sheltered features where snow is still soft to limit your exposure to lingering wind slabs.

Confidence

High

Avalanche Summary

No new avalanches have been reported in a few days.

Snowpack Summary

A variety of surfaces can be found at upper elevations including a crust on sun exposed slopes, wind slab and soft faceted snow in sheltered terrain. It is possible that wind slab has formed over sugary facets and surface hoar in isolated areas.

The mid pack contains several other crusts and layers of moist rounded grains.

Below treeline, most areas are below the threshold for forming avalanches.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

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.
