Strong southwest winds over the last few days built dangerous slabs on many wind-drifted slopes. The largest and most dangerous avalanches will break on northerly and easterly-facing terrain at upper elevations, like one seen near Independence Pass on Sunday. Avalanches may only break in the newly drifted snow, but some will break much deeper, near the ground and may run to valley bottoms. Avoid travel on or below steep wind-drifted slopes.
