Summary
Weather Forecast
The cold weather is expected to continue with only a slight increase in temperatures expected over the next few days. A few flurries are expected over the weekend along the divide with light to moderate alpine winds out of the West. Dress warm!!!
Snowpack Summary
Small wind slabs found in isolated alpine areas. 30-80 cm of settled snow over the November 12 crust. Stability tests on this crust are mixed, ranging from no results to easy results. This crust is more reactive in the Lake Louise area on southerly aspects above treeline. Rapid faceting and weakening of the snowpack with the cold temperatures.
Avalanche Summary
A few small loose dry avalanches observed in steep terrain Friday as the surface snow facets and weakens. Several recent natural and skier triggered slab avalanches have been observed on southerly aspects in the alpine running on the November 12 crust.
Confidence
Problems
Deep Persistent Slabs
The dominant issue in the snowpack is the November 12 crust (down 30-70 cm). This crust is evident throughout the region and has started to become reactive especially on South aspects just above tree line.
