A total of 49 tourists who had been stranded on Nanpeng Island in the South China Sea were picked up and moved to safety on Sunday morning, authorities said.

The tourists belonged to four camping groups visiting the uninhabited Nanpeng Island, some 35 km east of Zhapo, Yangjiang City in south China’s Guangdong Province, according to the Ministry of Transport.

Due to typhoon Talas, this year’s fourth typhoon, the tourists could not return home by themselves.

All the tourists were transferred safely to a rescue ship and a rescue helicopter dispatched by the Guangzhou-headquartered Nanhai Rescue Bureau of the Ministry of Transport.

China’s national observatory on Sunday morning renewed a blue alert for typhoon Talas, which is expected to hit Hainan Province and Beibu Gulf.
