Regions

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

Isolated pockets of stiff wind slab may exist, assess before dropping into your line.

Confidence

Moderate

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.

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

Friday

Sunny with some afternoon cloud. 20 to 40 km/h southeast alpine wind. Treeline temperature -4°C.

Saturday

Increasing cloud with precipitation 5 to 10 mm. 40 to 60 km/h southeast alpine wind. Treeline temperature 0°C. Freezing levels rising to 1800 m.

Sunday

Cloudy with precipitation 5 to 10 mm. Snow in the alpine. 20 to 30 km/h southwest alpine wind. Treeline temperature 0°C. Freezing levels 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

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.
