Regions

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

Expected wind could cause complex loading patterns in exposed areas due to reverse loading.

Seek out slopes with soft snow and no slab characteristics for the safest riding.

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 avalanche was reported, but field observations remain limited. Sunday, several natural wind slabs (size 1-1.5) were observed on easterly aspects at treeline in the McGregor range.

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

Snowpack Summary

55 to 80 cm of recent snow overlies a prominent hard crust formed in mid-December that extends up to 1800 m near the Pine Pass area, and up to 2000 m near Highway 16. Continued wind has redistributed the recent snow in exposed terrain at treeline and in the alpine.

A layer of surface hoar, facets, and/or a crust may be found buried around 120-140 cm deep. This layer has been observed to be gaining strength and is now even less likely to be triggered where bridged by the recent crust.

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

Weather Summary

Tuesday Night
Mostly cloudy. 30 km/h southeast ridgetop wind. Treeline temperature -18 °C.

Wednesday
Mostly cloudy. 50 km/h southeast ridgetop wind. Treeline temperature -18 °C.

Thursday
Cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -16 °C.

Friday
Cloudy. Up to 2 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -18 °C.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be careful as you transition into wind-affected terrain.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
