Authorities in southern China said Thursday that 39 people died in flooding after a tropical storm dumped heavy rainfall, as the country’s east coast and Taiwan prepared for a typhoon expected to make landfall in the coming days.

Most of the deaths were in Hengzhou, where the partial collapse of a reservoir dam sent torrents of water into the city and claimed 26 lives, said Ding Wei, the vice mayor of Nanning city, which has jurisdiction over the area. Nine people remained missing in the broader Guangxi region. 

Tropical Storm Maysak brought record rainfall to Guangxi starting Saturday, breaching reservoirs and stranding people for days in homes and other buildings. The previously announced death toll on Tuesday was six people.

A second storm, Typhoon Bavi, was at sea on a northwest track that would take it over some remote Japanese islands and then just north of Taiwan before making landfall in China’s Fujian or Zhejiang province on Saturday. Fishing boats could be seen tightly packed at ports in northern Taiwan on Thursday in anticipation of heavy rain hitting the island of 23 million people. 

Bavi, which brought violent winds to Saipan and other U.S. territories earlier this week, was downgraded Thursday from super-typhoon strength but still had maximum sustained winds of 184 kilometers (114 miles) per hour, according to Taiwan’s Central Weather Administration. Classes were suspended in several cities and towns in the Philippines and ships prohibited from leaving northern ports as the typhoon passed east of the northern island of Luzon.

In southern China, military rescue teams finished bringing out more than 10,000 trapped students and teachers from a cluster of schools in Guigang city, about 60 kilometers (40 miles) northeast of Hengzhou.
