Weather Forecast
Mild temps with small amounts of snow over the next couple of days. Winds expected to be light to moderate from the Southwest.
Snowpack Summary
Variable snow distribution at treeline and above. Wind slabs continue to develop in lee terrain features. Wind slab buried by recent light snow overlies a facetted snowpack and the basal October 27 rain crust. The crust is distributed unevenly in the forecast area. Facets and depth hoar are just off the ground. This weak base will persist longterm.
Avalanche Summary
Sunday observed several size 2's, likely solar initiated, on cross-loaded gullies above the weeping wall on Mt. Cirrus. They stopped mid-path. Saturday, we observed 2 size 3 avalanches on east facing cross-loaded alpine bowl near Mt. Saskatchewan/Wilson area, 2 size 2.5 on a similar aspect in the Winston Churchill range.Â
