Regions

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

New snow may be sitting on a layer of weak surface hoar and a crust.

Confidence

Low

Avalanche Summary

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

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

Snowpack Summary

5 to 15 cm of recent snow may have buried a layer of surface hoar that sits atop a widespread crust. The crust may be supportive at lower elevations, while it becomes thinner and breakable around treeline elevations. In the alpine, this crust appears not to exist, where roughly 20 to 30 cm of recent snow sits on various layers of crusts and facets.

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

Saturday Night

Mostly cloudy with no precipitation, southwest alpine winds 20 to 40 km/h, treeline temperature -6 °C.

Sunday

Cloudy with no precipitation, southwest alpine winds 10 to 30 km/h, treeline temperature -2 °C.

Monday

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

Tuesday

Mostly cloudy with no precipitation, south alpine winds 10 to 30 km/h, treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Keep in mind the crust offers an excellent bed surface for 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.
