Akamina, Crowsnest North, Crowsnest South, Elkford East.

Wind slabs at treeline and above may be reactive to human triggering. Seek out areas that have been sheltered from the wind for the best riding.

Confidence

Moderate

Avalanche Summary

No new reports on Wednesday.

Snowpack Summary

Previous strong to extreme westerly wind has scoured slopes in the alpine and formed wind slab on east facing terrain.

20 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects.

The mid and lower snowpack is generally well settled.

Weather Summary

Thursday Night

Cloudy with isolated flurries. 20 to 25 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Friday

Cloudy with new snow up to 5 cm. 10 to 20 km/h east ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
