    The interface between rapidly settling storm snow and the previous surface is characterized by crust and facets and new slabs are touchy in specific terrain - particularly steep, lee aspects below ridge crests.

Weather Forecast

20cm of snow possible by Friday in the Columbia Icefield Area, winds South to South west in the light to moderate range, temps to remain cool.  Pressure rising towards the weekend, producing clear skies and calm winds.

Snowpack Summary

Recent snowfall is settling rapidly and overlies a supportive mid-pack. This interface is characterized by crust and facets and new slabs are touchy in specific terrain, particularly steep, lee aspects below ridge crests. Intense wind scouring in the alpine.

Avalanche Summary

Avalauncher control work on Parker Slabs produced several size 2 soft slab avalanches up to 50cm deep and 50m wide. No natural activity was observed along the Icefields Parkway.

Confidence

Intensity of incoming weather systems is uncertain
