Regions

Kananaskis.

With the continued COLD, shorter days and more conservative objectives might just be the ticket. 

Confidence

Moderate -

Weather Forecast

It looks like the cold snap will stay with us a bit longer.  

Friday and Saturday: High temp of -20c and a low of -30c. Winds will be between 30-40km/hr from the East for both days as well as a mix of sun and cloud. Let's hope more sun than cloud.

Avalanche Summary

No new avalanches reported today. One new avalanche was reported yesterday through www.avalanche.ca.

Please refer to the MIN report on the map for further details.

Snowpack Summary

Lots of surface faceting with these cold temperatures. There is about 60cm of settled snow overlying the Jan 29 wind slab interface. Take the time to dig and evaluate this interface as there is still variability with it. Some wind effect in the alpine and our usual concerns for lee features and cross loaded gullies.

Terrain and Travel

  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex 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.
