Snowpack Summary

All elevations have had sustained NW to N winds in the strong to extreme range. Gusts of 111km/hr were recorded on the Nakiska Ridgetop station. As one would expect, the alpine windward aspects are gravel, and the lee aspects are scoured with patchy windslabs in many places. Treeline saw lots of snow transport from various wind directions. Expect new windslabs on any lee aspect.
