Regions

Kananaskis.

A little bit of a climatic change should help improve the ski quality a little bit. New snow will hide the heavily wind affected landscape. New windslabs will form on old hard and wind blown surfaces and the bond will remain a question mark for a few days.

Confidence

Moderate -

Weather Forecast

Cold air will move in to our region tomorrow mid day and in to Wednesday, Dropping down to -20. 

10-15cm snow is expected over the next 2 days. 

The winds will finally die down to reasonable values, for the first time in 10 days!

Avalanche Summary

No field trips today and no avalanches reported.

Snowpack Summary

With an additional bit of snow, This should help improve the ski quality a bit. However Wind slabs (both buried and on the surface) are widespread through the region, and are found in virtually all open terrain. If you look really, really hard there is good skiing in very sheltered terrain at lower elevations. The Dec 2 crust ,we have decided to remove it from the "Avalanche Problems" list.......at least for now.

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be aware of the potential for large avalanches due to the presence of a persistent slab.
  • Watch for areas of hard wind slab on alpine features.

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.
