The four climbers from the North Ridge Expedition will be postponing attempt on Monday and instead will push for the summit on Tuesday. The reason for this is that they want to assess the conditions ahead.
Most important to the climb from camp 4 is the Japanese Couloir. This was named after the Japanese expedition in 1982 took this route to the summit. It is an avalanche prone area that detours across the north face of K2. By taking this route it avoids a more difficult direct route up the ridge.
The climbers will determine the snow conditions in daylight. They expect alot of wind driven snow here.
The weather forecast for Tuesday is also good.
