Regions

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

Continuously assess for wind slabs as you transition into exposed terrain.

Rider triggerable wind slabs will likely still be found near ridge crests.

Confidence

Moderate

  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.
  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches have been reported in a few days.

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

Up to 30 cm of recent storm snow has been redistributed by south through northwest wind at treeline and above.

40 to 80 cm of well-settled storm snow overlies a prominent crust formed in mid-December that extends up to 2200 m.

Where the crust is thick and supportive, it effectively caps a few of the mid-snowpack instabilities, 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

Thursday Night

Partly cloudy. Up to 3 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -9 °C.

Friday

Mostly cloudy. 2 to 7 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday

Mostly sunny. 1 to 2 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -21 °C.

Sunday

Mostly cloudy. 2 to 4 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -13 °C.

More details can be found in the Mountain Weather Forecast.

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.
