You can trigger an avalanche where you find drifted snow on northwest to east through south-facing slopes, especially at upper elevations. Slides might break only within the drifted snow, but there is a good chance any avalanche will break into weak snow near the ground. Before the last storm, northerly and easterly slopes held the most weak snow. These slopes are the most likely places you can trigger a deeper avalanche. You may not see any signs of instability before you trigger an avalanche. Low-angle and wind-sheltered slopes are safer options.
