Kernpunkte

A widespread weak faceted base is the root of all concern. Be very cautious in all steep terrain for slab and loose snow avalanches.

Weather Forecast

Clear warm conditions with light winds expected until Tuesday night then there is the potential for some snow (up to 10 cm) with moderate SW winds.  (Don't hold your breath)

Snowpack Summary

SW (M-S) winds have built slab on top of a weak faceted snowpack on exposed tree line and alpine features. Mid-pack starting to loose strength.  Very weak faceted snowpack below tree line.

Avalanche Summary

A couple of sz 2.5 slab avalanches in the alpine (a cornice and natural) on south and NE aspects south of the Icefields along the Parkway observed on Saturday.

Confidence

The weather pattern is stable on Monday
