Another round of widespread skier triggered soft slab avalanches was reported by ski area avalanche crews on Wednesday. Some but fewer avalanches were reported Thursday so some stabilizing had occurred by Thursday. Friday Some light rain or snow should be seen mainly in the Olympics and north to central Cascades by Friday afternoon with a slight warming trend. Triggered avalanches should become likely on steep slopes by Friday afternoon. Further light to moderate rain or snow mainly in the Olympics and north to central Cascades and further warming should be seen Friday night. This should maintain or increase the avalanche danger on Friday night. Saturday Further light to moderate rain or snow especially in the Olympics and north to central Cascades should be seen through Saturday morning with further warming. The same danger is forecast for all aspects since rain and warming are not really discriminating when it comes to aspect.
