Avalanche Summary

Avalanche activity is expected in alpine and open treeline areas during and immediately after stormy periods.

Snowpack Summary

Total snowpack depth are probably over a metre in most treeline areas and deeper but more variable in the alpine, while below treeline areas are probably still below threshold depths for avalanches. Observations from the Shames area last week included a relatively uniform snowpack with a crust near the ground. Check out the Skeena/Babine discussion forum for more information.
