Avalanche Summary

An avalanche patrol down Highway 93 produced several size 1.5 slab avalanches in the alpine on reverse loaded features likely releasing in the past three days. Similar observations were seen in the Maligne valley as well.

Weather Forecast

Cold overnight temperatures will continue through the weekend with daytime highs being reasonable around -15 C. The anticipated light snow flurries expected mid week have moved up and some light snowfalls may arrive by Monday. Don't expect a lot of snow out of it, but the temperatures should warm up slightly with the cloud cover.

Snowpack Summary

Surface facetting continues with the cold temps. A Hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Below treeline where the snowpack exceeds 70cm, it has a supportive mid-pack.  Reasonable ski conditions can be found in sheltered features at tree line and below.
