You can trigger an avalanche on northerly, easterly, and south-facing slopes. You can trigger slides that only break in drifted snow, but the bigger hazard is slides that break in weak snow near the ground. On northerly and easterly aspects, weak snow is abundant close to the ground and slides can easily step down to this layer resulting in a large avalanche. You may not see any signs of instability before you trigger an avalanche. Low-angle and wind-sheltered slopes are safer options.
