Problem #1 Comments
Observed winds from the south being funneled every which way atop the E Ridge of Superior this morning from 7:30 on. On the ridgeline, those 25mph winds feel a lot stronger than they do on paper.
Cornices on the summit of Superior suggest wind loading from the NW. As such, lots of sensitive pockets of wind slab on S-facing that sluffed easily and exposed the underlying hard snow surface (photo 1).

Problem #2 Comments
I perceive slide for life conditions on steep S-facing terrain despite the new snow.
Comments
I am choosing the danger rating as Low for high elevation south-facing, as the old snow surface felt locked up and the new snow did not seem to pose a considerable avalanche hazard.
I can't say the same for north-facing. The observed wind loading from the south would make me reluctant to drop in on these aspects without seeing what the wind has deposited.
