Regions

Rossland, South Okanagan, Shuswap, North Okanagan.

Assess steep lines for wind slab before committing.

Rider triggerable wind slabs could still be found in steep terrain at treeline and above.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches have been reported since last weekend.

Thank you to those who have filled out Mountain Information Network reports, we appreciate the data.

Snowpack Summary

Below treeline a new, breakable crust could exist. In open areas at treeline and above, recent snow has been redistributed by strong southerly wind. As wind direction shifts to more westerly snow could be redistributed on to east facing terrain.

A prominent crust, formed in mid-December, is buried 30 to 50 cm below the surface and extends up to 2200 m.

In the mid snowpack, several other crust layers may exist. In the lower snowpack, a crust from mid-November can be found with facets above and below.

Weather Summary

Friday Night

Mostly cloudy. 1 to 2 cm of snow. 50 km/h northwest ridgetop wind. Treeline temperature -17 °C.

Saturday

Mostly sunny. 30 km/h northwest ridgetop wind. Treeline temperature -20 °C. Freezing level 0 m.

Sunday

Mix of sun and clouds. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -12 °C.

Monday

Mix of sun and clouds. 1 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -7 °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.

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.
