Regions

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

Winter has arrived. Watch for wind slabs in steep terrain at upper elevations.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

There were no new avalanches observed on Tuesday.

On Monday, naturally triggered size 1 storm slabs were observed, and loose dry sluffing in steep and sheltered terrain features.

Backcountry reports are very limited. If you head out, please post any photos or observations to the Mountain Information Network.

Snowpack Summary

Snow continues to accumulate, with many areas seeing 90 to over 130 cm of recent snow over a melt-freeze crust, with deeper deposits in wind-loaded terrain at treeline and above.

Early-season hazards remain a concern concealed beneath the new snow and will continue to be until the snowpack settles and becomes more supportive.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.

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.
