Avalanche Summary
Storm snow will quickly form cohesive slabs breaking on the weak, faceted snow that is already covering the ground. You could trigger avalanches from below, the sides, or a distance away. The weak snow coverage is most extensive on northerly to easterly-facing slopes near and above treeline, but you may find areas of old snow in other spots. Avalanche conditions will change quickly through the storm.
Winds will be drifting the storm snow, too. You could trigger small avalanches in just drifted snow above treeline on slopes with little previous snow.
