Meteorologists issue a severe storm warning for the Huai river valley, where 13 people have already lost their lives Weathermen are warning of more flooding along the Huai river in central and eastern China, where the worst floods in 12 years have already killed at least 13 people and caused more than 7 billion yuan (HK$6.6 billion) worth of damage. The China Central Meteorological Station yesterday issued a severe storm warning for the Huai river valley, which cuts through central Henan province, eastern Anhui province and Jiangsu province. Anhui has been hardest hit by the disaster. Zhang Zhitong, a vice-director of the State Flood Control and Drought Relief Headquarters in Beijing, was quoted by Xinhua as saying this year's floods along the Huai river were similar to those that hit the mainland in 1991. However, he expected the casualty figures would be much lower this time. Cheng Dianlong, another vice-director of the office, said the flood situation - although serious - was within 'manageable limits'. Mr Zhang said the main reason for the Huai river flooding was unprecedented rainfall. He said no major to embankments had been detected, and local officials agreed they were holding. State media said the real test would come in the next three days, when flood peaks could be more severe. Officials opened the floodgates at Wangjiaba in the western part of Anhui last week to allow a flood peak to pass. However, Xinhua reported late last night that embankments on the Danzi section of the Chu river south of the Huai had been breached after heavy rains yesterday.The agency said the city of Nanjing would be under threat if the main dyke of the Chu river burst. It said more than 300 policemen had been sent to reinforce the dyke. The Ministry of Civil Affairs estimates more than 21 million Anhui residents have been affected, by the floods, including nearly 400,000 evacuated from the disaster area. Officials have pledged to compensate farmers for their losses after authorities diverted water to seven areas to ease the flooding, which has ruined 1.16 million hectares of farmland, the Ministry of Civil Affairs said. More than 1.15 million people have been cut off from help as water surrounds 5,700 villages, the ministry said. Anhui has allocated nearly 25 million yuan in relief funds to affected areas. Torrential rains and rising water levels have hit other parts of the mainland, including the north, northeast and parts of the Yangtze river. The Yangtze River Flood Prevention Headquarters yesterday issued an emergency directive warning of possible large-scale flooding on the waterway and urging local governments to prepare. In the northern province of Shaanxi, heavy rain caused houses to topple, resulting in the deaths of at least four people in the capital, Xian. The rain also caused crop damage and cut a major railway line for three hours, China News Service reported. In the northeastern province of Heilongjiang, officials have sounded the alarm at the rising level of the Songhua river. Flood crests have been reported on some tributaries, Xinhua said.
