Regions

Clearwater, South Okanagan, Shuswap, North Okanagan.

Wind slabs in the alpine and isolated treeline pockets continue to demand caution—evaluate steep slopes for fresh wind effect.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported, but observations are limited at this time of year.

Please consider posting a MIN if you are heading out in the backcountry!

Snowpack Summary

Approximately 5 to 15 cm of new snow has accumulated over the last couple of days. At higher elevations, southwest winds have redistributed this snow into deeper wind-loaded pockets in leeward terrain. In sheltered terrain, the new snow has buried a layer of surface hoar.

A supportive crust sits about 30 to 40 cm below the surface throughout most treeline and alpine areas.

Below treeline, the snowpack thins considerably; many areas have only a shallow, crusty base—or in some locations, almost no snow at all.

Snow depths at treeline range from roughly 40 to 100 cm.

Weather Summary

Wednesday Night
Cloudy. 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Thursday
Cloudy. 2 to 5 cm of snow. 40 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Friday
Cloudy. 20 to 40 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Saturday
Cloudy. 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Snow is accumulating at higher elevations, despite lower elevations being almost snow-free.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be cautious of buried obstacles, especially below 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.
