Regions

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

Be cautious near sharp breaks in terrain, like ridge lines and gulleys that are exposed to the wind.Seek out areas where the surface snow is still soft.

Confidence

Moderate

Avalanche Summary

A few small (size 1) human triggered avalanches have been reported in the area around 2000 m on north and west aspects 20 to 40 cm deep.

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

Snowpack Summary

20 to 40 cm fresh snow accumulated over the weekend. At upper elevations, southwesterly winds redistributed snow to lee features. Fresh snow covered older snow in most terrain and surface hoar in isolated sheltered locations.

A surface hoar layer is now buried 30 to 60 cm and is most prevalent from 1700 to 2200 m. This layer has not been reactive to skier 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 interface.

There are no deeper layers of concern.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Investigate the bond of the recent snow before committing to your line.

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.
