Regions

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

20-40cm of settled snow has improved the skiing. Some cracking and whoomping is still occurring within the recent snow.

Cold temperatures out there. Be well prepared. Brrr......

Confidence

High

Avalanche Summary

No avalanches were observed in the Tent Bowl area or along the Spray.

Snowpack Summary

20-40cm of settled snow overlies a variety of surfaces from facets, hard wind slabs, and sun crust. Some of this recent snow has turned into localized wind slabs. It will take a bit of time for this new snow to bond with this interface. The mid pack is overall decent, mostly consisting of facet layers that were not reactive before the storm. Snow depths vary from 80-150cm depending on elevation.

Weather Summary

Please see the cold table below. Dress warmly given the cold temps. Even a simple gear malfunction can turn into a challenge.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be careful as you transition into wind-affected terrain.

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.
