Regions

Kananaskis.

Not a lot happening out there. The strong alpine winds might pose a sloughing problem with gully features in the alpine. Climbers pay attention to terrain above you as the wind continues.

Confidence

Good

Weather Forecast

A series of low pressures off the coast is keeping the flow from the W to NW. The winds at ridge line will stay in the strong to extreme ranges for the next while. No significant snow is forecasted to arrive in the next 2 days. Sunday may see a blip of light snow that may add up to 7cm. Temps will remain st the same range as today.

Avalanche Summary

No new avalanches

Snowpack Summary

Not much new to say here. TL & below is a bottomless mass, except for previously traveled areas. The alpine winds have redistributed most available snow to the Prairies.

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.
