Regions

East Kakwa, Robson, Tumbler.

Watch for wind slabs in lee areas. Start with small features before moving into bigger terrain. Observations are limited, verify conditions in your area.

Confidence

Low

Avalanche Summary

No avalanches have been reported in January.

Observations are limited. Consider posting a conditions report on the Mountain Information Network.

Snowpack Summary

Extreme northwest to southwest wind will likely have stripped all loose snow from exposed areas and deposited it far down slope.

The snowpack in this region is expected to be shallow with the middle and base made up of weak, sugary facet crystals. There is likely a crust at the base of the snowpack as well.

For an idea of old conditions in this area, see this report from our field team.

Terrain and Travel Advice

  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Wind slabs are most reactive during their formation.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.

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.
