Regions

South Okanagan, Shuswap, North Okanagan.

Light snowfall and strong winds will continue to build wind slabs at upper elevations.

Expect to find wind slabs farther downslope than usual.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

There were no new avalanches to report on Tuesday and Wednesday. Looking ahead, expect to see reactive wind slabs develop as the a bit new snow falls and the wind picks up.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

10 to 20 cm of recent snow overlies wind-affected surfaces or old settling storm snow. Recent strong wind has scoured south-exposed slopes and alpine features.

There are a couple of layers of surface hoar/facets or a crust that may be buried 20 to 45 cm deep. These layers have been mostly dormant, but they may become active in isolated areas where a sufficient slab forms overtop.

The remainder of the snowpack is well consolidated.

Weather Summary

Wednesday Night

Cloudy. 1 to 3 cm of snow. 30-50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday

Cloudy. 1 to 5 cm of snow. 30-60 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1400 m.

Friday

Mostly cloudy. 2 to 5 cm of snow. 30-50 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

Saturday

Mostly sunny. 20-30 km/h west ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Strong wind is building wind slabs farther downslope than usual.

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.
