Regions

South Coast Inland, Birkenhead, Coquihalla, Duffey, Manning, Skagit, South Chilcotin, Stein, Taseko.

Slide slow, homies. Rugged conditions like this really raise the stakes of a slip or fall.

Low

Avalanche Summary

No avalanches have been reported in the region yet this season. This will change when more snow arrives.

Snowpack Summary

Snow depths throughout the region range from about 30 to 60 cm, increasing with elevation. Some wind loaded spots may hold up to 90 cm.

No significant layers have been identified in this minimal snowpack, which is for the most part still below threshold depths for producing avalanches. Steep, isolated patches of wind-drifted snow could have the potential to produce small avalanches in alpine gullies and on smooth surfaces like rock slab.

Snow coverage starts at about 1200 metres and travel conditions remain generally rugged with ground roughness still too prominent to allow for straightforward travel on snow in most areas.

Weather Summary

Saturday Night

Clear skies. Alpine wind north 10-20 km/h. Above freezing layer in the alpine.

Sunday

Clear skies. Alpine wind variable or west 10-15 km/h. Treeline high temperature -3°C with an above freezing layer above 2000 m.

Monday

Clear skies. Alpine wind southwest 10-15 km/h. Treeline high temperature -3°C with an above freezing layer above 2000 m.

Tuesday

Clear skies. Alpine wind southwest 10-15 km/h. Treeline high temperature -4°C with a diminishing above freezing layer at 2000 m.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

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.
