Points saillants

While still under the influence of the high pressure weather system, expect minimal change. The current conditions do not preclude anomalous situations high in the alpine on steep terrain features. See avalanche in problem one.

    Windslabs exist up to a metre thick on lee slopes in the alpine. Solar aspects have greater likelihood of natural activity in the PM. Skiers triggered a size 2 avalanche, SW aspect high on Mt. Balfour. See picture @ acmg.ca/mcr.

    These are weakening in the sun with the inverted temperatures, and numerous collapses have been reported over the last 24 hours which can entrain wet snow, or be a big enough trigger to initiate a slab avalanche.
