Flooding in China’s southern city of Nanning has killed at least two people, officials said Monday, as Typhoon Maysak brought heavy rain and swelled rivers and reservoirs across the Guangxi region.

Maysak, which battered Vietnam and China’s southern island province of Hainan over the weekend, is now moving inland as a slower tropical system. Meteorologists said it would continue to dump the water it gathered over the South China Sea, increasing the risk of severe flooding.

In Nanning—home to nearly 9 million people—authorities raised the flood control emergency response to the highest level due to “extremely heavy rain,” citing concerns that conditions could worsen and hamper rescue operations. Reuters reported officials said around 55,000 people were affected by flooding, with waters overflowing or breaking through barriers at three reservoirs.

In the city of Guigang, about 270 km away, videos verified by Reuters showed floodwaters turning a main road into a lake, submerging cars and sending torrents down a hill into a construction site. The water level at the Guigang Hydrological Station rose to 42 meters by about 12:30 p.m., according to the Ministry of Water Resources.

Further south in Fangchenggang, Reuters-verified footage showed a small car being washed down a street as floodwater rose to another vehicle’s steering-wheel height, while a man struggled to keep an electric scooter from being swept away.

Authorities also warned of Super Typhoon Bavi approaching eastern China, with state media saying it could bring strong winds and heavy rain from Thursday. The U.S. National Weather Service said Bavi had winds up to 180 mph as it moved near Guam and other islands in the Pacific.

Maysak made landfall in Hainan on Friday, the first tropical cyclone to reach the Chinese mainland this year, and later made a second landfall in Vietnam on Sunday. Heavy rain continued as it crossed toward China, including reports of damage in Vietnam’s border areas before entering Guangxi.
