Regions

Kananaskis.

Very little snow has fallen in the past 2 weeks, and not much is expected in the near future. Conditions are quite static at the moment. The snowpack remains shallow and weak. Many ice climbs are in good shape.

Confidence

Good

Weather Forecast

The next several days will be overcast with occasional  light flurries, but very little accumulations are expected. Winds will continue to be strong from the West.

Avalanche Summary

No avalanches were observed or reported today.

Snowpack Summary

Little change from previously reported.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
