Strong winds are building new snow drifts on top of a weak snowpack. The most likely place you can trigger an avalanche is on slopes facing northerly and east near and above treeline. If you trigger an avalanche that breaks on the weak snow near the ground it can become larger than you expect. You may be able to trigger avalanches from below or from a distance. Shooting cracks are a sign you should move to lower-angle or wind-sheltered terrain.
