Avalanche Summary

Reports of moist size 1.0 avalanches have been running out of steep terrain features. If you and your friends have been out exploring and riding in the backcountry, and have some observations to share please send an email to forecaster@avalanche.ca.

Snowpack Summary

Snowpack observations and information are very limited, and conditions across the region vary.  In the alpine I suspect anywhere from 50-100 cm of snow. Storms slabs and wind slabs likely exist in the alpine and at treeline elevations. An early Nov rain crust (approx. 5 cm thick) is located near the ground at treeline, and possibly resting higher in the snowpack at alpine elevations. I have no further details on this crust, or it's bond to the upper pack.Snow depths at treeline are roughly sitting around 50-90 cm in depth, and below treeline snow levels may still be below threshold.
