TYPHOON Trami has slammed into China, bringing more rain and threatening to worsen severe flooding that has so far left 575 dead and 340 missing. Packing maximum winds of 126 kilometres per hour, the 12th tropical storm to hit China this year made landfall in the coastal areas of Fujian province's Fuqing City early on Thursday. It triggered heavy rains that are feared will exacerbate the worst floods in years in China, which have already affected nearly 80 million people, according to the State Flood Control and Drought Relief Headquarters. "We will prepare for the worst-case scenario," said Shu Qingpeng, a spokesman for the flood control office. The deluges have caused economic losses of up to 162 billion yuan ($A29 billion), the agency says. Across the north-eastern border in Russia, up to 40,000 people are at risk as waters in the Amur River rise to new levels near the city of Khabarovsk, according to Acting Governor Vyacheslav Shrot. "There've never been any water rises of this kind throughout the 120 years of hydrometeorology observations in the Amur area," he said. About 25,000 people have been evacuated from their homes in Khabarovsk. Trami left 17 people dead and affected more than 1.2 million in the Philippines, where flood waters up to 2 metres high shut down the capital Manila for three days. The floods caused damages to infrastructure and agriculture worth an estimated $US1.83 million, the National Disaster Risk Reduction and Management Council said. Before crossing to the Chinese mainland, Trami brought torrential rain to northern Taiwan, causing landslides, mudflows and accidents that injured 10 people. At least 6171 people were forced to evacuate homes, including more than 2600 staying in emergency shelters, according to Taiwan's Central Emergency Operation Center. Taiwanese weather authorities lifted sea and land warnings on Thursday as Trami blew away from the island.
