Regions

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

Watch for pockets of wind slab as you transition into wind affected terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Small amounts of dry snow accumulate over crusts and moist snow.

The mid and lower snowpack is generally uniform, with no significant layers of concern.

Below treeline, most areas are below threshold for avalanches.

Weather Summary

Saturday night

Around 5 cm of snow. 40 to 60 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Sunday

Mostly cloudy with 5 to 10 cm of snow. 50 to 80 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level dropping to 800 m.

Monday

A mix of sun and cloud with around 5 cm of snow. 30 to 50 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 500 m.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

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.
