Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

North wind may form small wind slabs on aspects that are typically windward.

Watch for small wind-loaded pockets especially around ridgecrest and in extreme terrain.

High

Snowpack Summary

In areas that still have snow available for transport, strong north wind may form small wind slabs on aspects that are typically windward. Widespread surface hoar has formed on all aspects at all elevations and a sun crust may exist on solar aspects.

10 to 25 cm of snow overlies a widespread thick crust that exists at all elevations.

Various weak layers persist in the mid to lower snowpack, however, triggering these layers is unlikely where they are capped by a thick crust.

Weather Summary

Sunny with cloudy periods. 20 to 30 km/h north ridgetop wind. Treeline temperature -12 °C.

Thursday

Sunny. 20 to 30 km/h northeast ridgetop wind. Treeline temperature -11 °C.

Friday

Sunny. 50 to 60 km/h southeast ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
