Storm snow will be redistributed by predominantly NW winds at ridgetops in the high alpine and m Easterly slopes at treeline.
Weather Forecast
Moderate to strong NW winds are redistributing the storm snow onto more Easterly aspects that may not have been previously loaded. Light snow flurries will occur through to Wednesday. Gradual warming is expected through to the end of next week.
Snowpack Summary
Total snowfall amount for this storm is 115cm and that tapers off south of Parkers Ridge. There appears to be a mid-pack weakness; likely facets, that is the most active. The entire year's snowpack is sitting over a weak base of rain crust and facets. Additional snow loading will occur on Easterly aspects from the NW winds.
Avalanche Summary
The colder temperatures appear to have locked the snowpack down. However during the storm, an extensive avalanche cycle occurred throughout the forecast area from Maligne south to Mt Wilson up to size 3.5. Avalanche control on Highway 93 north got limited results up to sz 2.5 with numerous sympathetic releases and buried the road at two locations.
