At the moment there is an avalanche risk on the North ridge of K2. This has the North Ridge expedition waiting till this risk dies down. This is in addition to the poor weather.
Snow has been falling with poor weather and it has set an amount of it on the ground. Maxut says that their experience – with 3 climbers having summited 13 8000m mountains – tells them that there will be an avalanche risk for a few days because of this new snow.
They are enjoying the rest period, but know that they cannot climb K2 with periods of good weather.
