Regions

North Rockies, East Kakwa, Kakwa, Pine Pass, Tumbler.

Strong westerly winds are expected to form fresh, reactive wind slabs. Watch for deposition near ridgelines and also in midslope features, further downslope than typical.

Confidence

Moderate

  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.
  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches have been reported in the past 5 days.

If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network

Snowpack Summary

Strong westerly winds have likely redistributed recent snow into deeper deposits on north and east facing slopes at higher elevations.

A prominent crust, formed in mid-December, is now buried 60 to 100 cm deep. This crust extends up to 1800 m near the Pine Pass area.

In thin snowpack areas, faceted grains or depth hoar may exist at the base of the snowpack.

Weather Summary

Sunday Night
Cloudy. 1 to 5 cm of snow. 80 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Monday
Cloudy. 1 to 2 cm of snow. 80 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Tuesday
Mostly cloudy. 2 to 25 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Wednesday
Mostly cloudy. 3 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
