Beijing: China's Wuhan city was on red alert on Wednesday for more heavy rainfall, after torrential downpours left parts of the city submerged. Transport links, water and power supplies in the city of 10 million are severely affected, and some residents were trapped in their homes, BBC reported. Flooding killed over 180 persons and caused chaos across China. Police in neighbouring Anhui province even warned that alligators from a farm there had escaped due to the flooding. Wuhan's meteorological office released the red alert in the city. It said to expect wind and rain, and flooding in both urban and rural areas. More than 560 mm (1.8ft) of rain has fallen over the past week, the heaviest ever in the history of the city, which is on the Yangtze River, local media reported. Roads and metro stations were inundated and trains cancelled.
