Regions

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

Good skiing can be found on solar exposed features at the moment. Once you tuck on to polar aspects the snow becomes very slow and grabby. The day time highs are slowly warming, but it is cold travelling through the valleys in the morning.

Confidence

High

Avalanche Summary

Two field teams out along the Spray today. With good visibility, neither team observed any new avalanches.

Snowpack Summary

Recent snow has settled to about 30cm at treeline and is becoming looser(facetted). Expect some recent windslabs in cross loaded gullies and isolated areas in the alpine. The Jan 30 interface is still a question in terms of location and character. It mostly seems to be either a melt/freeze crust, facet layer, buried wind slab or surface hoar. The midpack is supportive in most places, but in rocky areas it has become very weak and "punchy" while walking.

Weather Summary

Saturday will bring slightly warmer temps with a day time high of -17. The possibility of isolated flurries and West winds increasing to moderate..

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Avoid freshly wind-loaded terrain 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.
