Regions

Kananaskis.

Cold air has moved on and and forecast area is warm and windy with more to come - this translates into more suspect skiing conditions until we see some new snowfall - not all bad though - still some pockets of good skiing available.

Confidence

Good

Weather Forecast

Moderate winds will be predominantly from the NW with milder air continuing to push the cold arctic air to the east of us.  Some dribs and drabs of new snow over the next few days is all that is in the forecast - total accumulations of about 5cm.

Avalanche Summary

No new observed or reported.

Snowpack Summary

Warm and windy with very light flurries through the day - minimal accumulations.  Some minor redistribution along ridge tops onto n and E asp.  Midpack in thin snpk area <1m deep steadily Fc ing.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

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.
