Regions

Cariboos, Blue River, McBride, Premier, Quesnel, Clemina, Kakwa, Renshaw, Robson.

A bit of new snow and wind will promote wind slab development in high elevation terrain through the day Tuesday.

Confidence

Moderate

Avalanche Summary

There have been no reports of avalanche activity in the past 2 days.

Snowpack Summary

Expect to find 5-15 cm of new snow sitting on the snow surface above 1500 m. This is likely being redistributed by primarily southwest wind in alpine and treeline lee terrain. It likely sits on a crust or moist snow except on high northerly aspects where the snow has stayed dry.

The lower snowpack is settled and well bonded.

Weather Summary

Monday Night

Cloudy with 3-10 cm snow at higher elevations. Ridgetop wind southwest 30 to 50 km/h . Treeline temperature -3 °C. Freezing level 1400 m.

Tuesday

Mainly cloudy with 2 to 5 cm of snow at upper elevations. Ridgetop wind northwest 15 to 30 km/h. Treeline temperature -2 °C. Freezing level 1500 m.

Wednesday

Mix of sun and cloud. Ridgetop wind southwest 10 to 25 km/h. Treeline temperature 1 °C. Freezing level 1900 m.

Thursday

Mix of sun and cloud. Ridgetop wind southwest 10 to 25 km/h. Treeline temperature 1 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Carefully evaluate steep lines for wind slabs.
  • Wind slabs may be poorly bonded to the underlying crust.

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.
