Summary

Weather Forecast

Colder temps and light to moderate winds (N switching to Easterly) will predominate the area in the wake of Tuesdays snowfall, with mostly cloudy skies persisting through the week.

Snowpack Summary

A 'snowpack' exists above 2000m. Variable snow depths from 30 to 80 cm in the Columbia Icefields region. Windslabs exists on NE aspects. Inconsistent structure to the snowpack based on aspect, and elevation require careful evaluation for cohesion at any interface, and new slab development.

Avalanche Summary

Windslab development in lee areas, and gully features are most concerning. No direct observations or reports.
