Weather is the name of the problem right now: it has not been terrible but not good enough to move up the route.  Visibility has been lacking due to snowfall; of all things that help make navigating an icefall on a glacier easier, vilibility is #1.  Having cached a good amount of their food up on the route already, the team is running a little short on supplies; so they either have to push up to their cache and retrieve enough food to wait for better weather, or retreat to camp1 and resupply from a cache there.  All efforts are still centered on going up the route, the only question now is how best to wait it out.
