Regions

South Okanagan, Shuswap, North Okanagan.

Rider-triggered wind slab is the main concern.

Be careful with wind-loaded features, especially near ridge crests and rollovers.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

No new avalanche was reported.

On Sunday, explosive control work in alpine terrain around Big White produced several wind slabs (size 1.5) on north-to east-facing aspects with one persistent slab (size 2) that stepped down to the November crust.

Snowpack Summary

In open areas at treeline and above, the new snow has been redistributed by strong southerly wind. A prominent crust, formed in mid-December, is buried 30 to 50 cm below the surface and extends up to 2200 m.

In the upper snowpack, several other crust layers may exist. In the mid-snowpack, a faceted crust from mid-November can be found.

The snowpack depth is around 100 cm, tapering with elevation below 1500 m.

Weather Summary

Wednesday Night
Cloudy. 50 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level at 1300 m.

Thursday
Partly cloudy. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday
Cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Saturday
Mix of sun and clouds. 40 km/h northwest ridgetop wind. Treeline temperature -16 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.

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.
