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.

Observations are limited and early-season hazards are abundant.

Take a conservative approach and watch for signs of instability as you travel through terrain.

Confidence

Moderate

Avalanche Summary

In the past few days, avalanche observations have been limited to a few small (size 1) dry loose avalanches from steep terrain.

Observations are very limited at this time of year! If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

Up to 30 cm of recent storm snow has been redistributed by moderate variable winds at treeline and above.

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, but the geographical extent of this weak layer is still uncertain.

Treeline snowpack depths average 80-150 cm.

Weather Summary

Friday Night

Cloudy with up to 5 cm of snow expected. 15 to 30 km/h south ridgetop wind. Treeline temperature -6 °C.

Saturday

Cloudy with light snowfall. 20 to 40 km/h southwest ridge top winds. Treeline temperature -7 °C.

Sunday

Mainly cloudy with up to 5 cm of snow expected. 15 to 30 km/h southwest ridgetop winds. Treeline temperature -8 °C.

Monday

A mix of sun and cloud with light snowfall. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.

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.
