(Reuters) – Nearly 200 factories, including one run by Japanese car maker Honda Motor Co Ltd, closed in the central Thai province of Ayutthaya because of flooding, which could threaten Bangkok this week, officials said on Sunday. About 261 people have died since late July in flood-related incidents, the Department of Disaster Prevention and Mitigation said. Some 2.3 million people have been affected in the worst flooding to hit parts of Thailand in 50 years, mainly in the center, north, and northeast. The Rojana estate in Ayutthaya province, run by Rojana Industrial Park Pcl, was flooded after a wall of sandbags failed to hold back water overnight. “All 198 factories at Rojana have to be closed because the water is about 5.1 meters high,” Industry Minister Wannarat Channukul told Reuters. […] The commerce ministry said on Friday it had slashed its forecast for the main rice crop, which farmers are just starting to bring in, to 21 million tones from 25 million because of the flooding. Thailand is the world’s biggest rice exporter. The crop damage will add to the pressure on export prices, already being forced up by the high buying price set under a government intervention scheme aimed at helping poor farmers. Bangkok Governor Sukhumbhand Paribatra said in a statement the authorities were preparing an evacuation plan to move people from affected areas if floods hit the capital, much of which is just two meters above sea level. Some riverside areas have already suffered minor flooding but the level of the Chao Phraya River could rise sharply from October 15-18 when a large amount of water will reach the area from the north, where dams are close to overflowing, at a time of high sea tides. […] The death toll from two strong typhoons that cut across the north of the Philippines’ main island and left behind widespread flooding had risen to 101 as of Sunday, the national disaster agency said. At least 167 people had died in Cambodia by late last week and 15 in Vietnam.
