You can trigger an avalanche on west to north through east facing slopes where you find a cohesive slab resting on weak snow near the ground. Slopes in the alpine with wind-drifted snow are the most dangerous. You are unlikely to see any signs of instability before you trigger an avalanche. Low-angle and wind-sheltered slopes are safer options.
