Generally there is about 150 cms in the alpine, and treeline has been showing some variability between 50 -150 cms. There are locations in the alpine that have 200 cms plus already. On friday we received new information from the Selkirks south of Revelstoke that there was indeed a major avalanche cycle up to size 3.5 during the last storm, but it appears that most of the avalanches were sliding on a layer that is near the ground; perhaps a rain crust from October. This crust has also been highly reactive in the Lizard Range to the east. At this point we have heard no reports of this lower layer existing in the Kootenay-Boundary region; however, I think that we should at least be curious about the possibility of its existence as we gather information from data-sparse areas.Sunday's big system produced but a few centimetres of snow with freezing levels rising to 1800m, but winds were strong from the southwest. In the mid and upper snowpack, expect wind slabs and storm slabs resulting from this wind event and last weeks storms. With tuesday's forecast snow and wind, expect further wind and storm slab development.We hope to get some more information soon, as operators start getting out into the field. Any info from the field is welcome in our office. Let me know what you're seeing out there!
