Regions

Cariboos, North Columbia, Blue River, Clearwater, McBride, Premier, Quesnel, Sugarbowl, Clemina, North Monashee.

Additional snowfall and strong wind will increase the avalanche danger throughout the day.

Seek out slopes with soft snow and no slab characteristics for the safest riding.

Confidence

No Rating

  • 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

On Monday, natural wind/storm slabs (size 1.5 to 2.5) were observed on wind-loaded lee features at treeline and in the alpine. They occurred on north to easterly slopes and failed within the recent storm snow.

A notable persistent slab avalanche (size 3) was also reported from 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

45 to 80 cm of recent snow overlies a prominent hard crust formed in mid-December that extends up to 2200 m. Continued wind has redistributed the recent snow in exposed terrain at treeline and in the alpine.

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 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.

Snowpack depth is around 160 cm at treeline, tapering with elevation below 1500 m.

Weather Summary

Tuesday Night

Wednesday
Cloudy. 10 to 15 cm of snow beginning by mid-day. 50 km/h southeast ridgetop wind. Treeline temperature -6 °C.

Thursday
Partly cloudy. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday
Cloudy. 10 to 15 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Avalanche danger is expected to increase throughout the day.
  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.
  • 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.
