Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Isolated pockets of wind slab at higher elevations may be triggered in steep, unsupported terrain. Early-season hazards—like shallowly buried rocks and trees—remain a significant concern, both for travel and in the event of a fall or involvement.

Confidence

Moderate

Avalanche Summary

No new avalanches

Snowpack Summary

Wind slabs are still the dominant problem in alpine areas. Ridgelines, gullies and cross-loaded features are areas to pay close attention to as you move higher in the terrain.

The snowpack at upper elevations is still very shallow and weak, with lots of early season hazards poking through. At elevations below 2100m, rain crusts from October and November are generally supportive to ski travel.

Weather Summary

-10C forecast overnight with light winds. No new precip and a cloudy day is forecast for Thursday! Freezing levels around 1800m

Terrain and Travel Advice

  • Ice climbers should be equipped with avalanche safety gear.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

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.
