You can trigger an avalanche on west to north through southeast-facing slopes where you find a cohesive slab resting on weak snow near the ground. Pay particular attention to northerly and easterly facing slopes which held the most weak snow before last week's storm. Even very soft slabs can fail with such a weak snowpack beneath. Avoid traveling on and under slopes steeper than about 30 degrees. You can trigger avalanches from a distance or from below.
