Regions

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

Wind slabs may remain triggerable on lee slopes.

Carefully assess for slabs before entering big or committing terrain features.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanches have been reported. Observations have been limited with no field team in the area this week.

Wind slabs may remain reactive to triggering on Saturday; naturally triggered avalanches are unlikely.

If you head out, please consider posting your observations to the Mountain Information Network.

Snowpack Summary

Open areas and upper elevations have likely seen widespread wind effect from recent strong to extreme southwesterly winds. This has built wind slabs on lee north through easterly slopes.

A melt-freeze crust may be capping the snow surface on sunny slopes and at lower elevations.

Around 60 to 90 cm of dense settling snow may be overlying a layer of surface hoar. The likeliest place to find this layer is in sheltered areas at and below the tree line. There is uncertainty with its distribution and reactivity at this time.

The remainder of the snowpack is well settled with no additional layers of concern. Snowpack depths at treeline range from 95 to 250 cm, and there is still very little snow below treeline.

Weather Summary

Friday Night
Mostly cloudy. 20 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 800 m.

Saturday
Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature 2 °C. Freezing level rising to 2000 m.

Sunday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2400 m.

Monday
Mostly sunny. 30 km/h west ridgetop wind. Treeline temperature 5 °C. Freezing level 2200 m.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Carefully evaluate big and steep terrain features before committing to them.

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.
