Issued: Apr 18th, 2022 4:22PM

The alpine rating is moderate, the treeline rating is low, and the below treeline rating is low. Known problems include Wind Slabs and Loose Dry.

Brian Webster,

New snow on Tuesday will improve the ski quality but expect some fresh wind slabs in the alpine over the next couple of days.

Summary

Weather Forecast

10-20 cm of new snow above tree-line is forecasted by end of day on Tuesday. This will be accompanied by moderate to strong westerly winds. Temperatures will remain cool and decrease throughout the day with the passing of the frontal system.

Snowpack Summary

At treelline and above, 10-20 cm of facetted snow sits overtop of a varying thickness crust that exist on all aspects except high elevation north (above 2500m). There is widespread wind effect in most alpine locations. Multiple crusts exist within the mid-pack on all aspects/elevations except high north.

Avalanche Summary

No new avalanches reported or observed today. Several natural and skier triggered cornice failures have been observed over the past week.
