    Wind slabs 20-50cm thick near lees of ridgecrests are sitting on the Nov.6 crust or within the storm snow above.� These are currently very isolated in nature, but can be found on all aspects due to the easterly winds.

Weather Forecast

Cold temps will last for one more day before a weak NW to Westerly shift will bring some light precipitation and milder temperatures for Monday

Snowpack Summary

Facetting and slow storm snow settlement with cold temps. The November 6 crust is weak above 22000m but more developed at lower treeline elevations. I Isolated wind slabs in open areas.

Avalanche Summary

A large deep slab  avalanche was observed on the N Face of Mt.Haddo near Lake Louise that likely failed on old firn snow. This avalanche was a 3 and occurred on Wed., but shows that in the right location in the alpine things may not be so stable.

Intensity of incoming weather systems is uncertain on Monday
