Regions

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

Small human-triggered avalanches are possible where new snow has been wind-loaded over a hard crust.

Confidence

Moderate

Avalanche Summary

No new 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

5 to 15 cm of new snow accumulates atop a thick crust capping a moist upper snowpack.

A few buried crusts are found 100 to 170 cm deep. Reports suggest they are bonding well and are not a concern at this time. The mid and lower snowpack is well-settled and dense.

Weather Summary

Sunday night

Monday

Mainly cloudy with 2 to 8 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Tuesday

Mainly cloudy with 5 to 10 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Wednesday

Cloudy with 10 to 25 cm of snow. 40 to 60 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 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.
