Yesterday a skier triggered an eight inch deep wind slab on a southeast aspect of Mt Wister at an elevation of 11,000 feet. Similar events are possible today on isolated terrain features at the highest elevations. These stiff slabs may be up to a foot deep and could knock a person over and result in serious consequences in cliff areas, steep couloirs, hanging snowfields and other extreme terrain features. Clear skies and cold overnight temperatures allowed the snow surfaces to freeze overnight. It will be warmer today than it was yesterday. Sunshine and warmer temperatures will increase the wet snow avalanche hazard. Wet slides could release naturally or be human triggered on very steep slopes.
