Regions

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

Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.

Wind slabs are most reactive shortly after they form.

Confidence

High

Avalanche Summary

No new avalanches have been reported since Friday.

New wind slabs have formed in wind-exposed areas.

Snowpack Summary

Fresh wind slabs can be found in the alpine and treeline where the wind has deposited snow. The top 10 to 40 cm of snow is faceted (sugary crystals). The middle and lower snowpack consists of rounds and a few crust layers, these are of no concern at this time.

Weather Summary

Monday night

Mostly clear skies. 20 to 40 km/h southwest ridgetop wind. A temperature inversion sets up between 2000 m and 3000 m. Treeline temperature 0 °C.

Tuesday

Mostly sunny. 30 to 60 km/h southwest ridgetop wind. The temperature inversion starts to break down throughout the day. It lingers into the afternoon in the southern parts of the region. Treeline temperature 0 °C.

Wednesday

Cloudy with 5 to 15 cm of snow. 40 to 80 km/h west ridgetop wind. Treeline temperature -3 °C.

Thursday

Mostly cloudy. 20 to 40 km/h south ridgetop winds. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Use ridges or ribs to avoid areas of wind-loaded snow.

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.
