Regions

South Okanagan, Shuswap, North Okanagan.

Watch for pockets of wind slab on all aspects in the alpine. Practice good travel habits and think about what's below you.

Confidence

Moderate

Avalanche Summary

On Sunday several small dry loose avalanches and a small storm slab were reported near Sun Peaks.

Snowpack Summary

Alpine terrain is wind-affected, while sheltered areas hold soft snow. Cold temperatures may be facetting the upper snowpack,

A layer buried in early December is 50 to 70 cm deep. This layer varies, in the north of the region in sheltered spots its surface hoar while in the south its typically a crust.

The lower snowpack is strong and settled south of Highway 1, and potentially weaker and more faceted north of Highway 1.

The snowpack is 100-150 cm deep at treeline.

Weather Summary

Wednesday Night

Cloudy with up to 1 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Thursday

Cloudy with up to 3 cm of snow. 10 to 20 km/h south ridgetop wind. Treeline temperature -7 °C.

Friday

Cloudy with 5 cm of snow. 20 to 40 km/h southeast ridgetop wind. Treeline temperature -6 °C.

Saturday

Mostly cloudy with up to 5 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

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.
