Shanghai and its population of 23 million are preparing for the arrival of Typhoon Haikui.
Meteorologists tracking the storm say its moving towards the east coast and could make Shanghai within the next 24-hours.
Scientists say Typhoon Haikui is more powerful than Typhoon Matsa that hit the city in 2005 killing seven.
Authorities have been quick to act evacuating 400,000 people, suspending shipping and cancelling 150 flights.
Shanghai is the main city in the Yangtze Delta and the engine room of the Chinese economy responsible for around 40 per cent of the country’s output.
China was hit by two typhoons last weekend that left 23 people dead.
