Cave rescue effort imminent as divers arrive

Members of this tight knit community in Mae Sai, northern Thailand, know that cheap canada goose the return of seasonal monsoon rains will complicate any attempt to rescue the boys, who became stranded deep inside the tunnel network 14 days ago following a sudden flash flood.

Monsoon season typically lasts from July to October. During that time, water levels in Mae Sai, which sits nestled along Thailand’s mountainous border with Myanmar, can rise rapidly, flooding farmland and https://www.chinese-sharpei.de cutting canada goose uk shop off entire villages.

The Tham Luang Nang Non caves, where the boys are trapped, act as the town’s natural drainage basin during this period of heavy rains.

The boys and their 25 year old coach are huddled together in a small chamber four kilometers (2.5 miles) inside of the cave network, with a limited supply of oxygen.

To reach them, expert divers must carefully traverse jagged passageways, occasionally narrowing to the width of a person, forcing divers to remove their breathing tanks from their backs and enter like a pencil, taking extra care not to snag their wetsuit. The tunnels are pitch black. The water is muddy and cold. uk canada goose The whole journey can take up to six hours. Such is the volume of water extracted that entire nearby fields have been transformed into lakes.

The banks along the road leading to the cave’s entrance are now a freshwater stream, used by exhausted rescue workers each morning to bathe.

Earlier in the week, efforts to lower the water Canada Goose Online levels had generated an air of optimism. During a press conference Thursday, one Thai official suggested that the kids may even be able to “walk out.”

Such hopes have now vanished, replaced instead with a mounting sense of urgency. People at the large makeshift camp that now surrounds the caves liken the mood to that of a hostage situation.

Dark clouds drift ominously overhead. Weather forecasters predict heavy rains throughout the coming week.

The chamber in which the boys are located is no longer thought safe. Even if they are given enough food to wait out the rainy season, there is no guarantee that the ledge canada goose outlet online they are sitting on will not be submerged.

There are no easy decisions. But with the flood waters expected to rise goose outlet canada in the coming days, a canada goose outlet online uk decision will have to be made soon.

“The teams there will have a tipping point where they have to make that canada goose outlet store call to bring them out. To leave them there would almost certainly result in them drowning,” said one British mining engineer and experienced cave diver, who did not wish to be named due canada goose outlet reviews to the Canada Goose Outlet sensitivity of the subject.

“The tipping point will be related to how much rain is canada goose outlet store uk starting to fall, water levels inside, versus how the boys are canada goose jacket outlet doing. They’ll be looking at flow rates, recorded rain fall over the past weeks, months to get a rough indicator of where they’re at, they’ll have a deadline in mind, and then they’ll go for the most unpopular way out,” he added.

Each day rescuers at the Canada Goose Parka camp talk of differing strategies. Drilling holes, expanding the tunnels, pumping out water.

Though fraught with risk, friends and family had warmed to the idea, encouraged by news that diving teams from around the world had arrived on site to lend their expertise.

On Thursday, classmates of the boys at Prasitsart School had talked excitedly about their friends swimming bravely to safety with the help of foreign divers.

It would be “no problem” they assured us, their friends were more than capable, and besides they have the best divers in the world helping them.

On Friday, that option appeared to fade with news that a former Thai Navy SEAL, volunteering in the rescue effort, had died while swimming through the cave passageways.

No one in Mae Sai is prepared to think the worst, let alone say it aloud. But Canada Goose Coats On Sale the mood among the community is beginning to shift, as the reality of the situation takes hold.

At a school attended by one of the missing children a teacher asked how the boys could possibly complete a journey that was cheap canada goose uk too tough even for a former Thai Navy SEAL?

News cheap canada goose that some of the boys, especially the younger ones, are canada goose clearance sale suffering from malnutrition, has added to those fears.

In the town’s main market, where canada goose outlet new york city TVs remain permanently tuned to the news, people chatted nervously of the need to find other options. Surely, they can drill an opening in the roof of the cave, they canada goose outlet uk sale asked.

A WhatsApp group chat popular with some of the older school kids in the town said that a famous American engineer called Elon Musk was sending help. Maybe that would prove the difference.

But it is the families of the children who canada goose outlet canada feel these questions most keenly.

At the Anubanmaesai primary school, where the youngest of the 12 missing boys, 11 year old Chanin Viboonrungruang, is canada goose outlet nyc in his final year, the school’s principal talked of his concern for the boy’s parents.

“I’m afraid that the parents will begin to think the same thing will happen to their son,” said Radap Tate, of the Navy SEAL’s death on Friday.
