Regions: Birkenhead, Brandywine, Duffey, Garibaldi, Harrison-Fraser, Homathko, Sea To Sky, South Chilcotin, South Coast Inland, Spearhead, Stein, Taseko.

Seek out sheltered powder for better quality, safer skiing and riding. Have a plan to manage small wind slabs and sluff if you're tackling something steeper.

Avalanche Summary

There were no reports of avalanches on Monday or Tuesday, consistent with a steady decline in avalanche activity since the weekend storm.

Snowpack Summary

Large surface hoar is growing on the snow surface, particularly in sheltered areas. Thin melt-freeze crusts may be found on sun-exposed slopes.

These surfaces top 20 - 30 cm of settled recent snow that remains soft in sheltered areas but is heavily wind-affected in alpine and exposed treeline terrain. Cold temperatures are faceting this upper layer, causing snow grains to lose cohesion.

The most recognizable of several melt-freeze crusts in the lower snowpack is 100 - 150 cm deep in the Whistler area, decomposing, and not considered a problematic avalanche layer.

Snowpack height is around 120 to 150 cm at treeline and decreases rapidly below about 1500 m.

Weather Summary

Wednesday night

Mainly cloudy. 30 km/h northwest ridgetop wind. Freezing level 700 m.

Thursday

Cloudy with isolated flurries. 20-30 km/h northwest ridgetop wind. Treeline temperature -5 °C. Freezing level 800 m.

Friday

Cloudy with scattered flurries bringing les than 5 cm of new snow, mainly in the south of the region and continuing overnight. 35 km/h west ridgetop wind. Treeline temperature -6 °C. Freezing level 800 m.

Saturday

Cloudy with continuing flurries bringing new snow totals to 5 - 10 cm, mainly in the south of the region. 15 - 15 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Carefully evaluate steep lines for wind slabs.
  • Wind slabs are most reactive during their formation.

Avalanche Problems

Wind Slabs

Older wind slabs have largely stabilized. Small new slabs could form with northwest winds acting on slopes with soft, transportable snow.

Aspects: North East, East, South East, South, South West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
