Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina.

Continued light snowfall and moderate to strong west wind will keep wind slabs as the primary concern.

Confidence

Low

Avalanche Summary

No new avalanches have been reported in the past few days.

Data is very limited in this region. Please submit your observations to the MIN (Mountain Information Network)

Snowpack Summary

5 to 15 cm of new snow accumulated Tuesday night and Wednesday . At upper elevations, southwesterly winds have redistributed snow to lee features.

A surface hoar layer is now buried 40 to 70 cm and is most prevalent from 1700 to 2200 m. This layer has not been reactive to rider traffic, however we will continue to monitor it as more snow loads above it. Where there's no surface hoar, a crust is found at this layer boundary.

Weather Summary

Wednesday Night

Cloudy with scattered flurries, accumulation 3 to 6 cm. 30 to 50 km/h west ridgetop winds. Treeline temperature -5 °C.

Thursday

Mainly cloudy with sunny breaks and scattered flurries in the afternoon. 35 to 60 km/h southwest ridgetop winds. Treeline temperature -4 °C.

Friday

Mainly cloudy with flurries, accumulation 5-10 cm. 30 to 50 km/h southwest ridgetop winds. Treeline temperature -2 °C.

Saturday

Mainly cloudy with isolated flurries. 30 to 60 km/h southwest ridgetop winds. Treeline temperature -1 °C.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

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.
