Regions

South Coast, Powell River, North Shore, Sasquatch, Sasquatch, Tetrahedron.

Human-triggered avalanches are possible on steep wind-loaded slopes.

Confidence

High

Avalanche Summary

No recent avalanches have been reported in the region.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!

Snowpack Summary

10 to 20 cm of new snow will accumulate above a thick crust with some deeper wind deposits possible at higher elevations.

The snowpack below the crust is dense and bonded.

Weather Summary

Tuesday Night

Mostly cloudy. 35 km/h southeast ridgetop wind. Treeline temperature -4 °C with freezing level at 1000 m.

Wednesday

Cloudy with 10 to 20 cm of snow. 50 km/h southeast ridgetop wind. Treeline temperature -3 °C with freezing level at 1200 m.

Thursday

Stormy overnight with 10 to 20 cm of snow by midday then clearing in the afternoon. 30 km/h southeast ridgetop wind. Treeline temperature -2 °C with freezing level climbing to 1300 m.

Friday

Mix of sun and cloud. 30 km/h southeast ridgetop wind. Treeline temperature -2 °C with freezing level at 1300 m.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
  • 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.
