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

Now is a good time to explore!

If you see an increase in wind speed and drifting snow, windslabs are likely building and increasing the hazard.

Confidence

Moderate

Avalanche Summary

A few small, human-triggered, wind slab avalanches were reported in the region on Thursday in isolated features. We anticipate new windslabs forming when the wind speed increases tomorrow.

Snowpack Summary

Windslabs can be found in isolated features in the alpine and treeline elevations. Surface hoar (feathery crystals) are growing in sheltered areas. The top 10 to 40 cm of snow is faceting (turning into sugary crystals) with cold temperatures.

The middle and lower snowpack consists of rounds and a few crust layers, these are of no concern at this time.

Weather Summary

Friday night

Partly cloudy. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -10 °C.

Saturday

Mostly cloudy with 0 to 5 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -15 °C.

Sunday

Cloudy with 0 to 5 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Monday

Mostly cloudy. 20 to 30 km/h west ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.

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.
