Regions

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

Practice safe travel habits in the backcountry.

Frozen surface crust and thin snow cover may make travel challenging.

Confidence

High

Avalanche Summary

No recent avalanche activity has been reported.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

At high elevations, expect to find a dusting of new snow over a melt-freeze crust, and moist snow on the surface at lower elevations. Below the crust, the rest of the snowpack is generally settled and well-bonded.

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

Weather Summary

Saturday Night

Cloudy. 2 to 6 cm of snow expected above 1000 m. Light to moderate southwest ridgetop wind. Treeline temperature around -3 °C.

Sunday

Cloudy. 0 to 2 cm of snow expected above 900 m. Light to moderate southwest ridgetop wind. Treeline temperature around -3 °C.

Monday

Cloudy. Generally 5 to 10 cm of snow expected above 1200 m, with up to 30 cm on the west island. Strong southwest ridgetop wind. Treeline high around 2 °C

Tuesday

Mostly cloudy. 5 to 10 cm of snow expected above 1000 m. Moderate to strong southwest ridgetop wind. Treeline high around 1 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Carefully evaluate steep lines for wind slabs.

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.
