Regions

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

Isolated pockets of wind slab may be found in the high alpine on north through east aspects.

The best riding conditions will be found in wind-sheltered terrain.

Confidence

Moderate

Avalanche Summary

There are no recent avalanche reports for this region.

Isolated wind slabs may be found on north through east-facing slopes in the alpine.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

Surface hoar exists in wind-sheltered, and sun-sheltered open terrain. A thin melt-freeze crust may exist on south-facing slopes.

Above 1800 m on non-solar slopes, you can find 10 to 30 cm of snow above a thin crust. The crust disappears as you travel higher into the alpine.

Below 1800 m, 5 to 15 cm of snow sits overtop a thicker and more robust crust.

Snow depths at treeline are around 70-80 cm.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

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.
