Points saillants

Possibly more snow on the east side of the region due to the up-slope storm. There is definitely now enough snow to be concerned with from an avalanche perspective. Winter is here!

    Recent wind and snow have formed slabs on lee and cross-loaded terrain such as gully features. Some reverse wind loading is also possible from the NE winds.

    Recent snow has added a loose dry problem. Confined or exposed terrain is a concern, such as gullies, cliff edges and ledgy terrain. Ice climbers should be wary of overhead terrain.

Weather Forecast

Another 5 to 10cm of snow is possible before this storm blows out. A return to milder temperatures is expected for the rest of the week. Winds have been light to moderate during the storm with some wind from the NE.

Avalanche Summary

Isolated loose dry avalanches up to size 1.5 in steep Alpine terrain on N and E aspects have occurred in the past 48 hours.

Snowpack Summary

Up to 10cm of drier snow today fell on 10 to 20cm of generally heavy, wet snow yesterday. Wind loading is evident in lee and cross-loaded terrain in the Alpine and upper Treeline elevations. Minor reverse wind-loading is possible due to the recent NE winds. The early season crust is located approximately 10cm above the ground and is reported to be supportive to skiers weight in some locations. Basal facets exist below the crust.
