Regions

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

Enjoy the sun this weekend. Assess steep lines at upper elevations for lingering wind slabs.

Confidence

Moderate

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

Avalanche Summary

There is no new avalanche activity to report over the past few days.

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

Snowpack Summary

Many areas are 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 as the snowpack settles and becomes more supportive.

Weather Summary

Sunday

Mostly cloudy. 2 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 200 m.

Monday

Mostly cloudy. 2 to 10 mm of precipitation as snow or rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.

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.
