The boys, aged 11-16, and their 25-year-old coach disappeared after they went exploring in the Tham Luang Nang Non cave in the northern province after a football game on June 23.
Cave diving experts noted the key factors that have to be taken into consideration for the rescue: zero visibility given that the water in the cave is silted up, the distance from the cave entrance to the group at 1.9km, and the flow of water in and out of the cave.
While efforts to pump out floodwaters are continuing, some Thai officials have indicated that heavy rains forecast for this weekend could force them to decide the boys should swim and dive out using the same complicated route of narrow passageways through which their rescuers entered. Some of the boys can not even swim, making the first option even more daunting.
Huge volumes of water are being pumped out of the cave complex each day, but the narrow, winding passages inside the cave are still flooded, meaning diving through the murky water is now the only way in and out.
"We are happy to be able to help", Hanuni said and added he expects an attempt to extract the children to be made in the coming days.
Oxygen may yet become a problem should the water level rise and the air pocket they are in get smaller.
The divers who found the players said it took about three hours to reach them.
The boys and their coach were trapped in the cave by a sudden influx of water.
Efforts to open a communications line between the trapped team located 4km from the mouth of the cave suffered a setback after equipment fell into the water, Chiang Rai Governor Narongsak Osottanakorn said yesterday.
"For example, if we can accept the 90 per cent safety level, and if all conditions are at that 90 per cent, then we are ready to bring them out".
Though that could take months, as Thailand's rainy season typically lasts through October, experts say bringing the group food while they wait it out may be safer than untrained boys attempting to navigate through the dark and sometimes risky waters inside the cave.More news: Syrian rebels say peace talks with Russian Federation over southwest Syria failed
Some cave rescue experts have said it would be safer to keep the team supplied with essential food and medicine where they are for now and wait for the water levels to recede. Thailand's rainy season usually continues until the end of October.
It's also possible that conditions inside the cave could change.
It takes seasoned cave diving experts around six hours to reach the muddy ledge where the boys are sheltering around four kilometres (2.4 miles) into the cave. If cave floods again, it would much more hard to reach them.
"I believe the SEAL team can make it happen", he said.
A video released by the Thai navy showed the boys in their soccer uniforms sitting in a dry area inside the cave.
In the video, as a light is shone on each boy's face they address the camera with head bowed and hands clasped together in a Thai prayer-like greeting known as "wai".
Incessant rain has hindered operations to rescue the 12 school boys and their soccer coach from a cave in Thailand. One of them resembles the one worn by the England soccer squad in its Tuesday night World Cup victory over Colombia in Moscow.
He said authorities will evaluate the boys' readiness each day and if there is any risk, will not proceed with the extraction.
"It's like he has been given a new life", Kian Kamluang, whose 16-year-old son Pornchai is inside the cave, told the Associated Press.
They are also cooperating with Thai Navy colleagues and the wider global dive teams to stock dive tanks and other equipment throughout the route to aid the eventual evacuation of the isolated cavern.
