South Coast, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Assess conditions as you travel - any fresh snow is likely hiding early-season hazards.

Low

Avalanche Summary

No new avalanches have been observed or reported in the region, however, observations are limited at this time of year. If you head into the backcountry consider submitting a MIN report.

Snowpack Summary

At the highest elevations, recent wind-affected snow covers a melt-freeze crust and moist upper snowpack.

Snowpack depths at upper elevations grow to 80 cm, where snow begins to cover surface roughness. The snow-dirt line is found around 1200 m, and most solar slopes and below treeline are below the threshold for avalanches.

Weather Summary

Monday night

Clear and cold with increasing clouds. Light to moderate northeast wind, treeline low temperatures -10 C.

Tuesday

Cold. Flurries start in the afternoon with substantial accumulations beginning overnight. Increasing southwest wind, treeline high temperature -5 C.

Wednesday

Winter storm beginning late Tuesday with precipitation likely falling as snow at most elevations. 20-50 mm by morning and another 15 mm through the day, South wind gusting above 90 k/h. Treeline high -2, freezing level staying below 500 m.

Thursday

Cooling and clearing. Light northwest wind, treeling high temperature -4 C.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Exercise caution on steep, unsupported slopes.

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.
