    Moderate to strong S and W winds yesterday created slabs in lee areas. Slab thickness will range from 5 - 50 cm depending on how much new snow was available for transport. These slabs were unreactive today in the Lake Louise backcountry

Weather Forecast

A series of weak systems will bring minimal precipitation, overcast skies with some sunny breaks, and light to moderate W/ SW alpine winds for Tues, Wed, and Thurs. Alpine temperatures will remain in the -8 to -15 range.

Snowpack Summary

W of the divide, 15-25 cm has fallen over the last 3 days and been blown into fresh windslabs at treeline and alpine elevations. This sits on a well settled snowpack. Jan. 6th SH is visible in pits in some areas but is decomposing and unreactive. E of the divide, 5-10 cm has formed thinner windslabs which sit on top of a mostly facetted snowpack.

Avalanche Summary

No new avalanches observed on a field trip in the Lake Louise backcountry.
