Regions

Cariboos, Blue River, Clearwater, Premier, Quesnel, Clemina, North Monashee, Robson.

Be alert for wind slab formation, as recent low-density snow can be easily transported and redistributed by strong winds at higher elevations.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

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

Snowpack Summary

New, low-density snow continues to accumulate across the region, burying a variety of surfaces. These include firm, wind-affected snow at higher elevations or exposed terrain, and settled powder, with a chance of surface hoar at lower elevations or in wind-sheltered terrain.

Various melt-freeze crusts can be found in the lower snowpack, which are not concerning avalanche layers at the moment.

Snow depths at treeline roughly vary from 80 to 150 cm, and decrease rapidly at lower elevations.

Weather Summary

Thursday Night

Mostly cloudy with 0 to 5 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday

Mostly cloudy with 2 to 10 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Saturday

Mostly cloudy with 2 to 10 cm of snow. 50 to 70 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Sunday

Mostly cloudy with 0 to 2 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeine temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Watch for signs of slab formation throughout the day.
  • Closely monitor how the new snow is bonding to the old surface.
  • Be cautious of buried obstacles, especially below treeline.

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.
