Heavy rains will continue to batter the flood-affected southern Chinese provinces of Hunan and Fujian and the Guangxi Zhuang Autonomous Region over the next three days, Chinese meteorological authorities forecast Tuesday.

Rainstorms will hit Fujian, southeast parts of Hunan, and central and northern parts of Guangxi from 8 a.m. Tuesday to 8 a.m. Thursday, China's National Meteorological Center (NMC) said in a statement on its website.

Rainstorms will also pound eastern Jiangxi Province, western Xinjiang Uygur Autonomous Region, and southern Guangdong and Guizhou provinces, the NMC said.

On Monday, China's Office of State Flood Control and Drought Relief Headquarters dispatched work teams to the southern Chinese provinces of Hunan, Fujian and Guangxi and to western China's Xinjiang Uygur Autonomous Region after heavy rains hit the regions.

In Fujian Province, 24 are missing after heavy rains triggered flash floods and landslides Monday.

In Xinjiang, more than 200 households were evacuated Monday after a dam breached its levees.

The government launched emergency response plans Monday to help flood victims.

The rains in south China may interrupt Wednesday's Dragon Boat Festival, a traditional Chinese holiday.

Traditionally, the festival features dragon boat racing and the preparation of "zongzi", a glutinous-rice dumpling wrapped in bamboo leaves.
