Regions

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

Avalanches are possible where recent snow has formed a slab. Other early season hazards lurk below the surface. Check out our early season blog.

Avalanche Summary

No avalanches have been reported in the region yet this season. If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network 🙏

Snowpack Summary

10-20 cm of recent snow sits over various layers of crusts and old faceted snow and may also overlie isolated pockets of surface hoar in sheltered areas.

Treeline snowpack depths in the range of 30-60 cm.

Terrain and Travel Advice

  • Wind slabs may be poorly bonded to the underlying crust.
  • 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.
