Regions

Cariboos, North Columbia, Blue River, Clearwater, Premier, Quesnel, Clemina, Esplanade, Jordan, North Monashee, North Selkirk, Robson.

Watch for reactive wind slabs at higher elevations. Limited field observations and varied recent snowfall amounts increase uncertainty—monitor local conditions frequently.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported in the region.

A small (size 1) avalanche was observed recently in the north Monashees, it appeared that about 30 cm of new snow slid on a sun crust on a south-facing slope, below treeline. This avalanche likely occurred at least 3 to 4 days ago.

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

Snowpack Summary

Recent snowfall amounts have varied across the region, with new snow accumulating on a variety of surfaces. At higher elevations and exposed terrain, the new snow is settling on firm, wind-affected layers. In wind-sheltered areas and lower elevations, the new snow may have buried a layer of surface hoar.

Overall, the snowpack is generally well-bonded and stable, with some melt-freeze crusts present in the lower snowpack.

Snow depths at treeline range from 80 to 150 cm, with depths rapidly tapering off at lower elevations.

Weather Summary

Saturday Night

Mostly cloudy with 2 to 5 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Sunday

Mostly cloudy with 0 to 3 cm of snow. 10 to 30 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday

Mix of sun and cloud. 10 to 30 km/h south ridgetop wind. Treeline temperature -2 °C.

Tuesday

Mix of sun and cloud. 10 to 30 km/h south ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • 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.
