A powerful typhoon made landfall on the Chinese tropical vacation island of Hainan Friday after it swept south of Hong Kong, bringing many aspects of life in the region to a halt and forcing about a million people in the country’s south to leave their homes.

The Hainan province’s meteorological service said Yagi—earlier packing winds of up to about 245 kmph near its center—made landfall in the province’s Wenchang city at around 4.20 pm. It is expected to sweep toward other parts of the island before moving to the Beibu Gulf, it said.
