Weather Forecast

The high pressure ridge is starting to breakdown which will finally bring some snow (albeit light) at the beginning of the week. Upper elevation temperatures will fall back to normal for this time of year. Winds continue to be light.

Snowpack Summary

Variable wind slab in open or exposed terrain. Sun crust formed on steep solar aspects due to previous warm alpine temperatures. In most areas the snowpack is characterized by facets on a supportive mid-pack that is bridging basal facets.

Avalanche Summary

Numerous loose snow avalanches up to size 2 observed in the alpine in the Maligne Lake area Saturday on steep solar exposed gulleys. This activity will subside as the inversion dissipates and alpine temperatures fall on Sunday.

Confidence

The weather pattern is stable
