BEIJING — hina's densely populated eastern coast was preparing Sunday for the arrival of Typhoon Dolphin, which has triggered more than 1,000 flight cancellations, evacuations and a top-level alert from authorities.

Nearly 1,400 flights in and out of Shanghai's two main passenger airports had been cancelled on Sunday, state broadcaster CCTV reported.

Hangzhou's airport in nearby Zhejiang province saw 270 inbound and outbound flights cancelled, the report said.

Typhoon Dolphin, which brought heavy rain and strong winds to Japan's Okinawa in recent days, is expected to make landfall late Sunday or early Monday in Zhejiang or its neighbouring province of Fujian.
