Left C2 10th at 5:00 am, but high winds in afternoon slowed return. At 11:30 am weather worsening with huge cloud (thunder cloud). On at summit 4:00 through deep snow in places and no trials and had to fix rope. 20 minutes on top and then back to C2, at C2 at 9:30 pm. Difficult to find tent of C2 because cloudy and misty, then dark and had to be careful about crevasses, which problem slightly disorientated them. No more attempts for top.
