Avalanche Summary
There was report of a skier triggered avalanche outside the Shames ski area on Monday afternoon. There are however no specific details regarding this incident at the time this report was written.
Snowpack Summary
There has been around 15-25 cm of new snow in the Terrace area over the weekend. This new snow is possibly sitting on top of weak feathery surface hoar in sheltered areas. The upper snowpack varies substantially with elevation. Above around 1400 m, expect to find the new snow and lingering wind slabs. Below around 1400 m there may a crust just below the most recent new snow. For most of the region around 150 to 200 cm deep, a weak layer of sugary faceted snow buried on December 8 may still exist. It is likely that this layer was the culprit of a large, remotely-triggered avalanche on December 30 near Terrace, described in a MIN report here. The likelihood of triggering this layer is decreasing, but it could be triggered by humans in shallow snowpack areas.In the northern part of the region around Ningunsaw pass, a couple weak layers of feathery surface hoar may be found that were buried near the end of December. Expect to find these layers about 50 to 120 cm deep.
