Southern China is bracing for its second typhoon in a week, with shipping and flights already disrupted by heavy rain and strong winds ahead of Chanthu's expected landfall later on Thursday, state media said. Chanthu was upgraded from a tropical storm after gathering strength over the South China Sea. It is forecast to hit Yangjiang in Guangdong province and Qionghai on the resort island province of Hainan, the official Xinhua news agency said. Shipping between Hainan and the mainland has already been suspended and dozens of flights cancelled, it added. More than 26,000 fishing boats are also taking shelter in Hainan ports. At least 701 people have died since the start of the year as a result of torrential rains which have swept large parts of southern and central China, and another 347 are missing, the government said on Wednesday.
