Regions

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

It's cold, but not crazy out there. In fact its pretty good travel with clear skies. Ski quality? Poor. Experience? Well worth it.

Avalanche Summary

Nothing new today.

Snowpack Summary

Where to start? Valley bottom has 50-60cm of weak, loose facets with a thinly buried sun crust from days past. Treeline is a bit more substantial with a supportive snowpack of 80-100cm. The sun crust goes up to 2300-2400m. Windslabs start to appear at upper treeline, which may become more reactive with the chilly temperatures. The majority of our alpine snowpack blew away weeks ago, but we still have windslabs on east aspects, gullies and immediate lee areas.

See attached profile for specific details.

Weather Summary

Overnight low of -20, daytime high of -15. Broken skies, with some sun breaking through from time to time. Might be enough sun to take the edge off the -15. Winds will be basically calm with only slight breezes higher up. You can expect 3 flakes of snow...we've stopped reporting in cm. Individual flakes are more accurate these days. 5-8 flakes are expected later in the week.

More details can be found in the Mountain Weather Forecast.

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.
