Regions

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

New snow may be falling on surface hoar crystals.

If this is the case, avalanches will be easy to trigger especially in open, sheltered areas.

Confidence

Low

Avalanche Summary

There have been no reports of avalanches this week.

Please consider sharing any observations you have on the Mountain Information Network.

Snowpack Summary

New snow may be falling on large surface hoar crystals which have grown in most sheltered areas. Melt-freeze crusts are found on sun-exposed slopes and at lower elevations.

The mid-pack is generally well-settled.

Snowpack depth at treeline is 140 - 170 cm in the Knuckles. On the North Shore, depths are around 100 to 145 cm and diminish rapidly below treeline.

Weather Summary

Saturday

Cloudy with 5 to 10 cm of snow. 30 to 40 km/h west ridgetop wind. Treeline temperature -3 °C.

Sunday

Mostly sunny. 30 to 40 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2500 m.

Monday

Sunny. 10 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level 3000 m.

Terrain and Travel Advice

  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Watch for fresh storm slabs building throughout the day.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
