Regions

Kananaskis.

Finding sheltered areas will be key in enjoying a good day of skiing tomorrow. It's the transitional wind exposed areas that deserve some attention and possibly caution. 

Confidence

Moderate -

Weather Forecast

Overnight will have -10 as a low with -7 as a daytime high. There's a good chance it could be warmer as today's temperature was a bit under forecasted. Once again, we can expect random flurries to give a few centimeters, but not enough to change things much. Now, the best for last...the winds! Don't worry, they will continue to rage overnight, but they should fade slightly as the day goes by. Expect moderate winds at treeline with gusts into the strong range.

Avalanche Summary

Nothing new today.

Snowpack Summary

Lots of wind slabs out there of varying vintage. The newest ones are limited to crossloaded gullies at treeline and alpine. These latest slabs are resting on an older, very dense hard slab. As the temperatures stabilize this new/old bond will gradually improve. It doesn't feel spooky out there, but it does feel like a small slab could be kicked off in steeper terrain.

Terrain and Travel

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Approach lee and cross-loaded slopes with caution.

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.
