Regions

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

Continually assess your local conditions. Reactive wind slabs will likely persist at higher elevations following recent snowfall and strong winds.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

As much as 20 cm of new snow has buried a mixture of moist snow or old crusts. Below the recent snow, the snowpack is generally settled and well-bonded.

Below treeline, slopes are largely below the threshold for avalanches.

Weather Summary

Tuesday Night

Cloudy with 0 to 5 cm of snow at higher elevations. Freezing level 800 m. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday

Cloudy with 0 to 2 cm of snow at higher elevations. Freezing level 800 m. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday

Sunny. 20 to 40 km/h northeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1200 m.

Friday

Sunny. 20 to 40 km/h northeast ridgetop wind. Treeline temperature +2 °C. Freezing level 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
