Shanghai residents are being told to brace themselves as Typhoon Chanthu moves up the east coast.
Flights and train services are being cancelled and schools have closed due to heavy rainfall and high-speed winds affecting the region.
The storm has forced Shanghai's main container port, the worlds largest, to suspend operations.
Senior meteorologist Jason Nicholls says, "Chanthu will lose wind intensity as it continues to push northward just east of Shanghai into Wednesday."
