Regions

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

Use good travel habits.

Ride steep terrain one at a time and avoid riding above terrain traps.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the past couple days.

If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

A trace of new snow could bury a variety of surfaces including surface hoar on sheltered features and a sun crust on steep south facing terrain.

We are not tracking any concerning weak layers in the mid or lower snowpack at this time.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Be cautious of buried obstacles, especially below treeline.

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.
