Regions

Rossland, South Okanagan, Shuswap, North Okanagan.

The most likely place to trigger an avalanche is in freshly wind-loaded terrain features at upper elevations.

Confidence

Avalanche Summary

Explosive control work on Friday produced size 1-2 wind slabs out of steep alpine ridgeline lees. On Saturday, a skier reportedly triggered a small persistent slab avalanche in the trees, running on a crust buried in mid December.

Observations have been limited. If you head into the backcountry, consider sharing your observations with the Mountain Information Network.

Snowpack Summary

As small amounts of new snow arrive with wind, wind slabs continue to build in leeward alpine and treeline terrain.

The mid to lower snowpack contains a few crust/facet layers including one buried in mid December, now 50 to 70 cm deep. This layer may become a concern in the coming days as temperatures rise.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid freshly wind-loaded terrain features.

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.
