Westerly winds will continue to drift snow at the mid and upper elevations. Although most drifts will be found on leeward aspects facing north through southeast, cross-loading and the winds being channeled through terrain mean drifts may be possible on any aspect at the mid and upper elevations. These drifts will generally be 6-12" thick, and may break out widely in open, exposed terrain, possibly breaking above you.
Cornices are quite large along upper elevation ridgelines - avoid traveling anywhere near the edge of ridges as cornices may break back much further than expected. (Click to view this photo from Nathan Chaszeyka which illustrates how cornices have formed on both sides of an upper elevation ridgeline.)
