Lo esencial

Up to 20cm in the alpine possible by Boxing Day morning. Good for skiers, bad for climbers. A break from the snow Monday may tempt users to explore the big, steep places, but now is not the time. The consequences of causing a slide would be large. SH

Problemas de aludes

    Boxing day will see increased westerly winds up high, which form soft wind slabs in exposed areas, and near ridge tops. These will be easy for a climber or skier to trigger in steep terrain, and could step down to the deeper, weaker basal layer.

    These are becoming harder to trigger, but light loads can still cause avalanches on the basal depth hoar/October rain crust. The most sensitive trigger points are thin or crossloaded slopes. Stick to moderate angled areas with a thicker snowpack.
