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 large wet slab avalanches on steep slopes. Avoid cornices and the slopes beneath them.
After periods of snow and rain showers through the night, Monday looks be drier as high pressure moving in from the northwest begins to establish itself over the area. Temperatures in the mountains look to be in the low thirties in the morning with highs in the mid to upper forties during the afternoon. Winds will be light and variable. The general avalanche hazard will be Moderate tomorrow. The snowpack is warm and weak. The chance continues to trigger small wet slides that could entrain significant amounts of snow in longer paths, particularly at the mid elevations. Large cornices that have not failed will be fragile to human presence and could peel off naturally.
