Regions

North Columbia, McBride, Premier, Quesnel, Sugarbowl, Clemina, McGregor, Renshaw, Robson.

We have uncertainty in this region due to limited observations.

Verify conditions as you move through terrain and if in doubt, choose low consequence terrain.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.
  • Uncertainty is due to field data and reports showing a wide variation in conditions throughout the region.

Avalanche Summary

On Thursday a size 3 avalanche in extreme, unskiable terrain was reported but details are limited. No other avalanches have been reported in the past 4 days.

If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.

Snowpack Summary

Up to 20 cm of new snow is expected to have fallen by Sunday afternoon. This new snow will be accompanied by moderate to strong southwest wind, forming deeper deposits on north and east facing terrain.

60 to 100 cm of settled snow overlies a prominent crust formed in mid-December that extends up to 2200 m. Where this crust is thick and supportive, it caps a few mid-snowpack weak layers, making them difficult to trigger. These include a spotty surface hoar layer from early December and a crust/facet layer from mid-November. These layers may still be a concern in the alpine, where the crust is thin or nonexistent.

Weather Summary

Saturday Night

Partly cloudy. 1 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -20°C.

Sunday

Mostly cloudy. 5 to 15 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -13°C.

Monday

Mostly cloudy. 4 to 5 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Tuesday

Mostly cloudy. 2 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Use ridges or ribs to avoid areas of wind-loaded snow.

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.
