Regions

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

The winds are starting to have more of an impact in alpine terrain. Good skiing is still out there but its a bit more heads up for good quality. Lower elevation travel is still challenging....

Confidence

High

Avalanche Summary

A few new loose dry avalanches up to sz 1.5 from steep north aspects at 2700m.

Snowpack Summary

Lower elevations are still pretty rugged for travel in most areas. The crust that developed in November though is providing good travel opportunities!

Closer to treeline and above, winds have started to form windslabs 10-15cm thick on all aspects in immediate lees with the variable directions winds. The bond of the new snow to the rain crust is starting to facet out with the cooler temps, something to continue to monitor as new snow loads on top . The crust starts to disappear at around 2350m so be careful in the higher elevations to not hit rocks or other features if the crust is not present. The height of snow is about 60-100cm on average at treeline.

Weather Summary

Saturday will be a mix of sun and cloud with moderate westerly winds. Temperatures near -8C. Trace new snow over the next 24hrs.

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.
