Tides pose threat to water in Guangdong

GUANGZHOU: The most significant saltwater tides of the year will hit the shores of Guangdong Province over the coming days, a scientist said yesterday.

Due to a series of recent astronomical factors, costal cities, such as Zhuhai, will encounter huge daily tides from Saturday to Monday.

Li Jianji, director of the Guangdong astronomical society, said that at 6 pm on Saturday, the Earth and the moon will be at the closest they have been all year - 360,815 km apart. This will cause what is known as a perigean tide.
