The alpine rating is Wind Slabs., the treeline rating is , and the below treeline rating is Known problems include
Old wind slabs remain reactive to riders especially where they are sitting on a crust or a weak layer.
Seek out areas with soft snow on the surface that are sheltered from the wind.
North winds early last week have driven a natural windslab cycle in mostly south facing terrain. Avalanches averaged between size 1-2 with only a few size 2.5 avalanches reported. Ski cuts are still producing small wind slabs in isolated terrain at treeline and alpine elevations.
Check out this MIN for more details.
Avalanche activity has tapered off and no new avalanches have been reported over the weekend.
Last week's strong northerly winds created wind slabs in exposed areas at treeline and above on south and westerly faces.
10-20 cm of snow fell in the region last week. This snow sits on a crust up to 1400 m - 1900 m. In areas east of Quesnel and Williams Lake, reports say there is also a weak layer of surface hoar with the crust.
Two more layers of surface hoar may be found buried between 90 and 150 cm at treeline. The likelihood of triggering these layers is low, but is most likely in shallow rocky areas at upper treeline.
The current snowpack is shallow and variable in structure throughout the region.
Mostly cloudy with up to 3 cm of snow, west alpine wind 20-40 km/h, treeline temperature high -22 °C.
Mostly cloudy with up to 5 cm of snow, variable alpine wind 20-30 km/h, treeline temperature -16 °C.
Partly cloudy with up to 5 cm of snow, east alpine wind 10-40 km/h, gusting 60 km/h, treeline temperature -18 °C.
Mostly sunny, with no new snow, east alpine wind 10-30 km/h, treeline temperature high -18 °C.

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- The best and safest riding will be on slopes that have soft snow without any slab properties.
Recent winds have built slabs at and below ridgetops in atypical areas. These slabs are likely to be more reactive where they overlie a weak layer of surface hoar and/or a crust.
