Points saillants

The weekends storm snow is settling fast but unfortunately, the snow quality is deteriorating just a quickly. Good skiing can still be found in sheltered areas but that will change as the temperature drops.

Snowpack Summary

A sun crust is developing on the surface. Waterton received 40cm of snow in the townsite & 20cm at Cameron Lake over the weekend. This storm was accompanied by easterly winds so expect reverse loading. The new snow is settling fast thanks to high daytime temperatures. The midpack is strong, though weaker basal facets still lurk in thin areas.

Avalanche Summary

Multiple natural size 1- 1.5 dry loose avalanches observed in steep alpine lee slopes on Sunday.
