Regions

Kananaskis.

Remember that avalanches are still possible at low. Don't turn the radar off!! The northern portion of the region (Tent RIdge) still deserves some assessment before launching.

Confidence

High

Weather Forecast

Cloudy tomorrow with isolated flurries. No significant accumulation. Alpine temps will be steady at -13 overnight and hang there for tomorrow. Winds will still be light at all elevations.

Avalanche Summary

Nothing new was seen today

Snowpack Summary

No new snow or wind to speak of. In fact, tracks from yesterday were still fresh and clear in the alpine. The alpine snowpack is showing no sign of any significant windslab. Occasionally one can be felt buried underneath the top 30cm, but these are often small and isolated to ridgecrests. Treeline is a similar condition. Loose dry snow in almost all areas. One thing that was noticed today was a buried windslab where the down flow (cold air settling), wind prone areas. Probing will reveal this layer. Below treeline there's been no change. Some surface hoar developed yesterday in valley bottom areas. Snow depths are: Burstall Pass 106cm, Mud Lake 80cm

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.
