Persistent weak layers of faceted snow that formed during the extended dry periods in November and at the end of December remain a real concern. Many avalanches involving these layers have occurred over the last week. Above 8000 feet these slabs could have depths of four to seven feet. At lower elevations, isolated pockets of slab could be triggered with depths of one to two feet.
