Regions

Kananaskis.

Brrrr....COLD is the theme. Good skiing can be found at all elevations. Read the snowpack summary before travelling into the alpine.

Confidence

High -

Weather Forecast

COLD...Tuesday morning will start out around -27c and warm up to -21c by late afternoon. Expect light winds out of the west with overcast skies and light flurries. Very similar for Wednesday except for the fact that temperatures will drop down to -37c that night.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

We are looking at about 60cm of settled snow from these recent storms and just over 2m total snow at tree line. The interface with the storm snow is progressively getting stronger but take the time to dig and evaluate this interface before committing to larger features. Some wind effect in the alpine and our usual concerns for lee features and cross loaded gullies. First a global pandemic, and now a Kananaskis snowpack with no depth hoar!!! Who would have thought we'd see both of those in a single lifetime, let alone a single winter?

Terrain and Travel

  • Be careful as you transition into wind affected terrain.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Avoid areas where the snow feels stiff and/or slabby.

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.
