You could trigger a dangerous avalanche on north, northeast, and east-facing slopes at all elevations. The snowpack is thin in this area, and you can impact buried weak snow layers near the ground. The most dangerous areas are where a cohesive slab of wind-drifted snow rests on top of these weak layers. Assess the snowpack carefully before traveling on and under steep slopes. To reduce your chances of being caught in an avalanche avoid traveling on wind-loaded terrain features on the lee-sides of a ridgeline or in a northeasterly-facing gully or couloir. Safer travel options exist by sticking to wind-sheltered slopes at lower elevations.
