The State Flood Control and Drought Relief Headquarters on Sunday activated a level II emergency mechanism to cope with approaching Typhoon Sarika and Haima.
Typhoon Sarika is expected to make landfall in Hainan on Tuesday morning, while Typhoon Haima will hit Guangdong in south China on Thursday.
Heavy rain and gales will affect the southern coastal areas in the coming days, according to the headquarters.
The headquarters urged local authorities in south China to take precautions and sent six work teams to Hainan, Guangdong, Guizhou and Yunnan provinces as well as Guangxi Zhuang Autonomous Region to prepare for aid and relief.
China's State Oceanic Administration also issued a storm warning on Sunday, as coastal cities in Hainan and Guangdong will see heavy precipitation up to 180 centimeters from Monday to Tuesday.
