Torrential rain has continued to batter the mainland's central, eastern and southern provinces, killing 94 people and displacing more than 500,000 over the past week. At least 25 people were still missing and about 16.7 million people in the provinces of Jiangsu , Anhui , Henan , Hubei , Sichuan and Shaanxi and the city of Chongqing had been affected by floods and landslides, Xinhua said. More than 1.2 million hectares of crops have been ruined and 49,000 houses destroyed in the past week, with total economic losses estimated at 3.8 billion yuan, Xinhua said. Heavy rain in the central province of Henan and the eastern provinces of Anhui and Jiangsu saw the Huai River, one of the country's largest and a primary water source for a sixth of the population, overflow by alarming levels during the past week. The water level was still rising yesterday and a flood peak was expected today, Xinhua said. Zhang Zhitong , vice-director of the national flood-control office, said the situation was 'extraordinarily dire' and a team was checking embankments along the river. Nanjing , the capital city of Jiangsu province, had 258mm of rain over the weekend, the heaviest fall in the past decade, Xinhua said. Rainstorms caused power blackouts and left main streets deep in water. The southwestern province of Sichuan was among the worst-hit regions. About 30 people have been killed in the east of the province since July 2, after what is reported to have been the worst flooding in the province's recorded history. Li Weihua , a meteorologist from Sichuan, said the frantic pace of construction in major cities in the province had contributed to the extreme climate conditions. Rainstorms have also wrought havoc in parts of the normally dry province of Shaanxi in the northwest. Further heavy rain was forecast for more than 10 provinces yesterday, the National Meteorological Centre said on its website. Weather authorities have also warned that two or three typhoons or tropical storms could hit this month.
