Regions

Cariboos, North Columbia, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina, Esplanade, Jordan, North Monashee, North Selkirk, Shuswap, East Kakwa, Kakwa, Renshaw, Robson, Dogtooth, Central Selkirk.

Be cautious of wind slabs on all aspects near ridgelines. Remember recent wind directions have varied.

Sheltered terrain features will hold the best riding conditions.

Confidence

Moderate

Avalanche Summary

Avalanche observations are limited to small dry loose avalanches in steep and sheltered terrain features, and size 1-2 slabs in wind-affected terrain on all aspects.

Observations remain limited this early in the season. if you head into the backcountry, please post to the Mountain Information Network!

Snowpack Summary

Surface conditions includes wind affected snow in exposed areas, and up to 30 cm of settling snow in sheltered terrain features.

A crust buried in early November is 50-90 cm below the surface. In some places, there may be weak facets or surface hoar above this crust. Observations are limited this early in the season. While the extent and reactivity are not fully understood, we have not had recent reports of avalanches or test results on this layer.

Treeline snowpack depths average 80-150 cm.

Weather Summary

Sunday Night

Mostly cloudy with isolated flurries possible. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -14 °C.

Monday

A mix of sun and cloud with light snowfall. 10-30 km/h westerly ridgetop wind. Treeline temperatures around -8 °C.

Tuesday

A mix of sun and cloud. Westerly ridgetop winds increase over the day to 40-60 km/h. Treeline temperature -8 °C.

Wednesday

A mix of sun and cloud with possible flurries. Westerly ridgetop winds remain strong, around 50 km/h. Treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • 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.
