Regions

South Okanagan, Shuswap, North Okanagan.

Be careful as you transition into wind-affected terrain where triggering is most likely.

The best and safest riding will be on slopes that have soft snow without any slab properties.

Confidence

Moderate

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

Avalanche Summary

Recent explosive control work on north-to east-facing aspects in the alpine terrain produced wind slab and storm slab avalanches up to size 2. Some large slabs stepped to the November crust, 50 cm deep, producing very large avalanches.

Sluffing has been observed on steep sheltered slopes where low-density snow has not been affected by the wind.

Snowpack Summary

An additional 5-10 cm of low-density snow has accumulated on top of the previous storm snow, bringing the total to 25-50 cm. This has been redistributed by southerly wind over a prominent crust formed in mid-December that extends up to 2200 m. Below this, several other crust layers may exist in the upper snowpack.

A faceted crust from mid-November can be found in the mid-snowpack. Snowpack depth is around 1 m, tapering with elevation below 1500 m.

Monday
A mix of sun and clouds. Up to 2 cm of snow in the afternoon. 40 km/h south ridgetop wind. Treeline temperature -6 °C. Freezing level 1000 m.

Tuesday
A mix of sun and clouds. 40 km/h south ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -5 °C.

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.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Be careful as you transition into wind-affected terrain.

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.
