Regions

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

Despite forecasted winds they didn't arrive on Wednesday. Winds have been here earlier this week though so watch for pockets of windslabs in open areas above treeline.

Confidence

Moderate

Avalanche Summary

No new avalanches or reports today.

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 on all aspects 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.

Weather Summary

Thursday will bring a mix of sun and cloud, trace flurries and light to moderate winds out of the NW. Temps will be around -6C.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • 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.
