Strong west and northwest winds during the storm blew and drifted snow onto leeward slopes, primarily at upper elevations. Most of these drifts have gained strength and stabilized, but you are still going to want to remain cautious, especially if you are getting into steeper, higher terrain. The danger is greatest on upper elevation slopes facing N-E-SE. Cross loading is also a factor - look for drifts on the lee sides of gully walls and beneath rock outcroppings. Wind drifts are recognizable by their smooth, rounded, "pillowy" appearance, and cracking in the snow surface is a sign of instability.
