*The Chinese city of Wuhan is on red alert for more heavy rainfall, after torrential downpours overnight left parts of the city submerged. *
Transport links and water and power supplies in the city of 10 million are severely affected, and some residents are trapped in their homes.
Flooding has killed more than 180 people 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 on Wednesday. It said to expect wind and rain, and flooding in both urban and rural areas.
Chinese media is reporting that more than 560mm (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.
Roads and metro stations were inundated with water, and trains cancelled.
Caught in the floods – Robin Brant, BBC News in Wuhan, eastern China
The last leg of the journey home for some people leaving Wuhan train station tonight is on foot, wading through the water.
A handful of couples passed me as I stood, almost up to my knees in it, at the traffic lights under the highway overpass by the railway station. A few coaches made it through the temporary pond, as did a few lorries. But there was no rush hour traffic in the worst hit suburbs tonight.
There is some respite; the rain has stopped for now. But as I write this there are still cars driving the wrong way down a highway slip road because the rain has blocked their route.
