Strong southwesterly winds yesterday and last night continued to create slabs of drifted snow on leeward slopes near treeline and above. Several inches of fresh snow, and continued westerly winds will add to the mix and you are likely to find a smattering of shallow fresh drifts intermixed with older, stiff slabs. You are most likely to encounter slabs of drifted snow on northwest through southeasterly aspects, with the highest concentration on upper elevation N-E facing slopes. Look for recent drifts on the leeward sides of ridge crests and terrain features such as gully walls, sub ridges, and rocky outcrops. Suspect slopes that have a smooth, rounded appearance, or that sound hollow underneath. Cracking is a sign of instability. Even a small wind slab avalanche could have serious consequences in the wrong terrain.
