There's still areas, these tight, twisting tunnels that even experienced divers have difficulty going through. a diver said you have to take off your tank, put it behind you. the tunnel is the size of his body. there's not a lot of room for error here. they have had millions of gallons of water come out of the cave system. the threat is the water levels are going to rise once it started to rain. they have 13 sets of equipment that have been set inside, ready for the boys. again, it's trying to also determine what their order of evacuation would be. do they take out the strongest first, the wea...

>> reporter: the issue, of course, is that this cave system has been flooded. they've been pumping millions of gallons of water out for the past week or so. the pumps have been running 24/7 and it is now at a point that about a third of the journey -- it is a nearly three-mile journey. about a third is walkable, but it is an exhausting walk. it is from the cave entrance to where the water's edge is, it is about a 90-minute walk. for these experienced divers who are physically fit, the royal navy divers doing this for a living, they're exhausted by the time they reach the water. they need to si...

Necessary to have an evacuation attempt of these boys and their coach. they were taking in air hoses, oxygen tanks, and he ran out of oxygen coming back out. his fellow divers tried to revive him and could not. it is a reminder of the dangers that lurk inside and the sort of decisions and risks that officials are calculating in trying to undertake this effort, which would involve taking 12 boys and a coach who don't know how to swim and getting them from where they are, which is nearly three miles deep into the cave system, to the cave entrance. >> yeah, absolutely heartbreaking, these images ...

The oxygen level in the cave system is deteriorating. and this is posing a new wrinkle and a new concern. last night they were taking in hoses and trying to pump in air to increase or to improve the environment there. but with the number of divers who have been going in or out, there's only so much air in that controlled system. so they believe that it's becoming more and more unstable. there is the sense that there's going to be a decision imminently because the conditions, frankly, are never going to get better and they can only get worse. they've continued to pump water out of the cave syst...

Were trying to take supplies into the cave system last night in preparation for a possible evacuation attempt. it is a reminder of the sort of risks that are being calculated here by thai officials as they decide how to bring the boys out and, more importantly, when. they need to decide the order of evacuation. do they bring the strongest out first, the weakest, the youngest? we are told there are at least three of the kids and the coach who are perhaps not quite strong enough to make this sort of escape, so we're awaiting hour-by-hour and, of course, watching the skies because there is the ex...
