We prussick-climbed the first 3 dripping pitches, then it was wet up through the first pitch after the bivy ledge (simul climbed the chimneys). Then on to summit at 8:10. It started raining and sleeting on the descent that involved a lot of misery and a stuck rope. The next morning everything was covered in snow.
Amazing, but a lot of work in the conditions. I'd say it is a good bit harder than .10a Maybe .10+
