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

Stay off wind-loaded slopes and be mindful of overhead hazard, especially during periods of strong sun.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed in the past few days.

If you head out in the backcountry, let us know what you are seeing by posting a MIN report.

Snowpack Summary

Up to 20 cm of new snow arrived Friday night with strong southeast switching to northwest wind creating wind slabs on a variety of aspects in exposed terrain.

This new snow overlies a crust in most places and wind-affected surfaces in exposed areas.

The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth has been reported as 330 cm at 1700 m, tapering quickly at lower elevations below treeline.

Weather Summary

Friday Night

Mostly clear with valley could. 5 to 20 km/h northwest ridgetop wind. Treeline temperature -3 °C.

Saturday

Mostly sunny with valley cloud. calm to 20 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Sunday

Mostly sunny with valley cloud. calm to 20 km/h northwest ridgetop wind. Treeline temperature -2 °C.

Monday

Increasing cloud cover. 20 to 40 km/h northwest ridgetop wind. Treeline temperature rising to +1 °C. Freezing level rises to 2500 m.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.

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.
