Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Sugarbowl, Clemina, North Monashee, East Kakwa, Kakwa, Renshaw, Robson.

Generally safe avalanche conditions exist. However, remain cautious in areas without a supportive surface crust or where new snow has accumulated over a crust.

Confidence

Moderate

Avalanche Summary

A group of riders remotely triggered (from 60 m away) a size 2 storm slab avalanche on a west aspect in the alpine on Saturday. The group was stopped in a safe spot on a flat bench when the avalanche released on a convex roll on the adjacent slope.

Several other naturally triggered storm slabs up to size 2 were reported on sunny aspects in the alpine.

If you are getting out into the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network).

Snowpack Summary

Anticipate crusty snow surfaces in all but north-facing alpine terrain. In some areas, as much as 10 cm may sit atop these old surfaces.

A series of crusts exist in the upper snowpack.

Weather Summary

Monday Night

Mostly cloudy with 0 to 5 cm of snow. Freezing level dropping to the valley bottom overnight. 0 to 20 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Mostly cloudy with 0 to 5 cm of snow. Freezing level 1200 m. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -8 °C.

Wednesday

Mix of sun and cloud. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -5 °C. Freezing level 1500 m.

Thursday

Mostly sunny. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -3 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • Carefully monitor the bond between the new snow and old surface.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Be alert to conditions that change with aspect and elevation.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.

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.
