Rain has further weakened the warm snowpack, particularly at the mid elevations. Above 9000 feet, a few inches of new snow with moderate winds has fallen overnight. In steep terrain at the mid and high elevations, wet loose slides could be human triggered, involving the new snow as well as the older snowpack. Cornices on high ridge lines are also a hazard today as they have been weakened by consecutive warm days. Evaluate terrain carefully today and identify features or areas where the wet slide activity is more likely.
Wet loose slides are possible in very steep terrain on a variety of aspects. These slides could begin as a few inches of surface snow and then entrain deeper and deeper layers of snow in steep and long slidepaths.
Large overhanging cornices could fail due to sustained warm temperatures at the higher elevations. Cornice failures could trigger wet slab avalanches on steep slopes. Avoid cornices and the slopes beneath them.
