BANGKOK » Advancing floodwaters in Thailand breached barriers protecting Bangkok’s second airport Tuesday, halting commercial flights at a complex that also houses the country’s flood relief headquarters and thousands of displaced people.
The flooding at Don Muang airport, which is primarily used for domestic flights, is one of the biggest blows yet to government efforts to prevent the sprawling capital from being swamped. Its effective closure is certain to further erode public confidence in the ability of Prime Minister Yingluck Shinawatra’s administration to defend the increasingly anxious metropolis of 9 million people.
Bangkok’s Suvarnabhumi Airport, the country’s main international gateway, has yet to be affected by flooding and flights there were operating normally. Most of the city has been spared inundation so far.
Don Muang has come to symbolize the gravity of the Southeast Asian nation’s deepening crisis, which has seen advancing waters drown a third of the country and kill 366 people over the last three months.
The airport houses the government’s recently established emergency Flood Relief Operations Center, and one of its terminals has been converted into an overcrowded shelter filled with tents for about 4,000 people who fled waterlogged homes.
Somboon Klinchanhom, a 43-year-old civil servant who took refuge there last week, was preparing to move after authorities said the terminal had become too crowded and thousands of people displaced there would be relocated.
"I thought it would be safe and well-protected," Somboon said of the airport, as she packed her belongings again.
Though floodwaters have yet to spill across Don Muang’s runways, ankle-high water could be seen Tuesday rushing over sandbagged barriers around the airport’s perimeter, swamping internal roads. One vast pool was headed toward two Thai Airways jetliners parked outside a hangar, their wheels wrapped in plastic sheets.
The two main carriers based at Don Muang announced they were suspending operations and diverting flights to Suvarnabhumi because of the flood threat. They are Thai Orient Airlines and Nok Air, which said it was halting flights until Nov. 1.
Capt. Kantpat Mangalasiri, the airport’s director, said Don Muang’s commercial runways would be closed until Nov. 1 to ensure safe aircraft operations.
Thai air force flights carrying relief supplies were continuing on a military runway that is still open, air force spokesman Montol Suchukorn said. He said floodwaters had breached the military’s air base, but the runway remains protected by flood barriers.
Last week, the air force moved 20 planes from Don Muang as a precaution.
The government’s flood relief command will remain at the airport for now since it is still accessible by road, spokesman Wim Rungwattanajinda said.
He said the government expects floodwaters will sweep through the main parts of Don Muang by Friday, but would not rise above 3.3 feet (one meter).
The scene at the domestic terminal was chaotic as throngs of confused passengers struggled to leave or pulled up to the departure hall with luggage, unaware their flights had been canceled.
With parts of the main road heading to downtown Bangkok flooded knee-deep, taxis were in scarce supply. Some travelers waited hours for a ride as airlines scrambled to arrange special buses.
Don Muang, located on Bangkok’s northern outskirts, is among seven of the capital’s 50 districts that the government has declared at risk. Those zones, in the north and northwest, are all experiencing some flooding.
Last week, Yingluck ordered key floodgates opened to help drain runoff through urban canals to the sea, but there is great concern that rising tides in the Gulf of Thailand this weekend could slow critical outflows and flood the city.
On Tuesday, Gov. Suhumbhand Paribatra said he was concerned about record-high water levels on the Chao Phraya river, the city’s biggest waterway. He said the river could spill over its banks and the situation would likely grow worse as high tides set in.
The government, meanwhile, declared public holidays on Oct. 27-31 in affected areas, including Bangkok. The Education Ministry also ordered schools in 12 affected provinces and the capital to close until Nov. 7 due to the floods.
Late Monday, the flood relief center said water levels in the worst-hit parts of the country — the submerged provinces north of Bangkok — were stable or subsiding. But the massive runoff was still bearing down on the capital as it flowed south toward the Gulf of Thailand.
While neighborhoods just across Bangkok’s boundaries are underwater, most of the city is dry and has not been directly affected by the deluge.
Anxious Bangkokians, though, have been raiding stores to stock up on emergency supplies, and many have been protecting their homes and businesses with sandbags. Some have even erected sealed cement barriers across shop fronts.
