Regions

North Columbia, McBride, Premier, Quesnel, Sugarbowl, Clemina, 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

Low

  • 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.

A notable persistent slab avalanche (size 3) was reported on Monday. This avalanche was naturally triggered on a north-east alpine slope near Clemina Creek. This very large avalanche ran in a path that does not commonly run, and is suspected to have stepped down to the November crust.

Snowpack Summary

20 to 40 cm of recent storm snow has been redistributed by south through west wind at treeline and above.

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 of the 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 high alpine, where the crust is thin or nonexistent.

Weather Summary

Friday Night

Partly cloudy. 1 to 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -22 °C.

Saturday

Mostly sunny. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -22 °C.

Sunday

Mostly cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -13 °C.

Monday

Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Approach lee and cross-loaded slopes with caution.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
