Shifting winds have blown and drifted the new snow and the potential for finding an unstable wind slab exists on all aspects at upper elevations. Wind drifts are recognizable by their smooth, rounded appearance and cracking is a sign of instability. Fresh drifts should be shallower and less consequential on southerly aspects but they will also be poorly bonded to the underlying slick crusts. On northerly aspects, new wind drifts continue to pile up on top of old, and in these areas, a triggered wind slab has the potential to step down into a buried persistent weak layer causing a deeper and much more dangerous avalanche.
