Regions

Cariboos, North Rockies, McBride, Quesnel, Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Wind slabs may be reactive to riders especially where they are sitting on a crust or a weak layer.

Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported by Tuesday afternoon.

Pockets of wind slab may be reactive to rider triggers, especially on southerly facing slopes.

Snowpack Summary

New snow up to 20 cm with moderate to strong northeast winds may have formed fresh wind slabs. Dry loose sluffing from steep terrain features is likely as the new, low-density snow may show a poor bond to old snow surfaces including surface hoar, faceted snow and wind-pressed snow.

A crust up to 1900 m is found down 30-50 cm. In areas east of Quesnel and Williams Lake, reports say there is also a layer of surface hoar associated with the crust. This may also exist in sheltered alpine terrain features.

The midpack is reportedly well-settled and supportive.

Weather Summary

Tuesday Night

New snow 5-10 cm. Ridgetop wind 10-20 km/h from the west. Treeline temperatures near -15 C.

Wednesday

Cloudy with possible sunny periods and flurries. Ridgetop wind 10- 20 km/h from the northeast and treeline temperatures near -15 C.

Thursday

Mix of sun and cloud. Ridgetop wind 15-20 km/h from the southeast. Treeline temperature -10 C.

Friday

Cloudy with isolated flurries. Ridgetop wind light from the southeast. Treeline temperatures near -5 C.

More details can be found in the Mountain Weather Forecast.

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.

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.
