Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Identify features of concern as you move through the terrain by continually investigating the bond between storm snow and the underlying crust.

Confidence

Low

Avalanche Summary

No new avalanches have been reported in this region. However, observations have been minimal throughout the early winter.

Backcountry users should expect to see evidence of a natural wind slab avalanche cycle, likely size 1 to 1.5, at higher elevations in steep unsupported terrain.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Snowpack Summary

In the alpine, 20 to 30 cm of wind affected snow overlies a series of crusts and facets.

At treeline and below 5 to 15 cm of recent snow overlies a layer of surface hoar that sits atop a widespread crust. The crust is supportive at lower elevations, while it becomes thinner and breakable around treeline elevations.

Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards present at or just below the snow surface across all elevations.

Weather Summary

Monday

Mix of sun and cloud with no precipitation, west alpine winds 10 to 20 km/h, treeline temperature -4 °C, freezing level 1500 m.

Tuesday

Mix of sun and cloud with isolated flurries, southwest alpine winds 20 to 40 km/h, treeline temperature -4 °C, freezing level 1000 m.

Wednesday

Mainly cloudy with isolated flurries, trace accumulation, southwest alpine winds 40 to 60 km/h, treeline temperature -1 °C, freezing levels rise to 1500 m.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • 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.
