South Coast, Powell River, Tantalus, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

30 to 40 cm forecast snow and strong wind will form touchy storm slabs.

Make conservative terrain choices and avoid overhead hazard.

Confidence

Low

Avalanche Summary

Forecast snow and wind Monday night will form large storm slabs reactive to human triggers on Tuesday.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

30 to 40 cm forecast snow and wind Monday night will form touchy storm slabs reactive to human triggers on Tuesday.

The new snow overlies a crust on all slopes except true north facing terrain at upper elevations where the previous snow remained dry.

Below treeline is either snow free or has very thin snow coverage. Expect difficult travel at lower elevations.

Weather Summary

Monday Night

Snow, 30 to 40 cm (rain below 1000m). 40 to 50 km/h southwest ridgetop wind. Treeline temperature -2° C. Freezing level 1400 m.

Tuesday

Mix of sun and cloud. 20 to 30 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

Wednesday

Mix of sun and cloud. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1600 m.

Thursday

Cloudy with isolated flurries, 0 to 5 cm. 30 to 40 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
  • Be especially cautious as you transition into wind affected terrain.
  • Use small low consequence slopes to test the bond of the new snow.

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.
