China warned of serious flooding after many southern and eastern provinces experienced some of the worst storms in decades. The Yangtze, Huaihe and Xijiang rivers may see "quite large" floods this year due to unusually heavy rain, according to the State Flood Control and Drought Relief Headquarters in a statement.
