Weather Forecast

Cold air from the Yukon floods into our region as a arctic high pressure system builds. Cold easterly winds and clear skies will remain in place most of the week. For more details: Avalanche Canada's, Mountain Weather Forecast.

Snowpack Summary

30cm of low density snow fell since Saturday in the ice fields area, less in Maligne and around the three valley confluence. This layer is sitting on a variety of surfaces depending on elevation and aspect and seems to be bonding well. Surface hoar may be sporadically preserved in some sheltered locations.
