Slabs of wind drifted snow, both old and new, remain the concern out there. Deeper wind drifts that formed earlier in the week have largely stabilized, but there may be some isolated slabs that remain sensitive to the weight of a skier or rider. Approach steep slopes that have a smooth, rounded, or pillowy appearance with caution, especially in areas of consequential terrain.
With south facing surfaces crusted over, there isn't a lot of snow available for transport, but the strong winds we've seen are capable of eroding these crusts, stripping snow from southerly aspects, and depositing it on to northerly facing slopes. Look for fresh deposits of wind drifted snow on the leeward sides of ridge crests and terrain features such as gully walls and sub-ridges. Stiff slabs may sound or feel hollow underneath, and cracking is a sign of instability.
