SHANGHAI, July 30 (Reuters) - Shanghai relocated more than 280,000 people, halted hundreds of flights and ferry services and imposed speed limits on roads and railways on Wednesday as a tropical storm whipped eastern China with gales and heavy rain.
Co-May's landfall in the port city of Zhoushan in Zhejiang province in the early hours of Wednesday was soon followed by warnings of a tsunami set off by a powerful earthquake off Russia's far east, raising concerns of larger-than-expected storm surges along the Chinese coast.
While the winds from Co-May were weaker than those generated by typhoons, the Chinese financial hub and other cities in the Yangtze River delta have taken no chances.
At least 640 flights could be cancelled at Shanghai's two main airports on Wednesday, including 410 at Pudong and 230 at Hongqiao, authorities said.
All ferry services in Shanghai had been cancelled since Wednesday morning, and drivers were told to drive under 60 kph (37 mph) on highways, local media reported.
Shanghai's Disneyland and Legoland remained open. But some rides and performances would be suspended at Legoland due to weather conditions, the park said.
Airports at nearby cities Ningbo, Wenzhou and Hangzhou also saw flight cancellations and diversions. As of Wednesday morning, more than 75% of Wednesday's flights at Zhoushan had been cancelled.
Some train services in the region were temporarily suspended with others operated under restricted speeds, state media said.
Shanghai is rarely subject to direct hits from strong typhoons that generally make landfall further south in China. The most significant typhoon in recent years that landed directly in Shanghai was Bebinca last year, the most powerful tropical cyclone to hit China's financial capital since 1949.
Co-May made landfall in Zhoushan in the early hours of Wednesday with maximum sustained wind speeds near its centre of 23 metres per second (83 kph). Forecasters expect Co-May to make another landfall closer to Shanghai later on Wednesday.
The storm coincided with a tsunami triggered by a magnitude 8.8 earthquake off Russia's Kamchatka Peninsula on Wednesday, about 4,000 km (2,500 miles) from Shanghai.
China's National Marine Environmental Forecasting Center said the tsunami was expected to have a "disastrous impact" on some parts of China's coast, including Shanghai and Zhoushan.
The natural resources ministry also issued tsunami warnings for the two cities, which could be hit by waves of up to 1 metre in height in the early evening.
Warnings of waves of up to 3 metres have been declared along Japan's Pacific coast due to the tsunami.
Tsunamis generated by earthquakes are capable of travelling thousands of kilometres across vast oceans without loss of power.
