Regions

South Okanagan, Shuswap, North Okanagan.

Watch for small, isolated pockets of wind slab at upper elevations.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

Throughout the week, small human-triggered wind slabs (generally less than size 1) have been observed in wind-affected terrain.

If you are heading into the backcountry, please share your observations by posting a MIN.

Snowpack Summary

Approximately 10 cm of snow accumulated over the past week now overlies a thick, supportive crust extending to mountaintops. At higher elevations, southwesterly winds have likely redistributed this recent snow in exposed terrain.

The remainder of the snowpack is well-settled and strong.

Weather Summary

Friday Night
Partly cloudy. 30 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Saturday
Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.

Sunday
Mix of sun and clouds. 2 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Monday
Mix of sun and clouds. 1 to 10 cm of snow. 30 km/h northwest ridgetop wind. Treeline temperature -9 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

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.
