9-12" of fresh and recent storm snow has been redistributed by strong winds Wednesday night that continue to gradually ease through Thursday night. This has produced a patchwork of slabs that remain reactive at middle, and particularly upper elevations. Slabs may exist well below ridgelines, on mid-slope rollovers and even down-canyon gullies. You might not see the typical wind-textured snow lurking if the storm ends with light winds. Therefore, use clues such as the texture of the snow, looking for firm or punchy layering, difficult trail breaking, or hollow feeling snow. Also anticipate the slopes that may be wind-loaded from the pattern of cornices. At upper elevations, avoid steep wind-loaded slopes; steer around more committing and poorly supported features at middle elevations. Keep in mind that some small slabs could exist even in lower elevation terrain, but they should be small. Keep in mind that if winds do pick up from the SE ahead of the next system, some slabs could form in activevly loading areas on atypical aspects.
