BEIJING, June 16 (Xinhua) -- China's National Meteorological Center (NMC) issued a rainstorm alert Wednesday as heavy rains were expected to pound the flood-affected southern provinces.

Most regions in south China, including provinces of Guizhou, Jiangxi, Zhejiang, Guangdong, and the flood-hit Fujian, Hunan and Guangxi Zhuang Autonomous Region, would experience heavy rain or rainstorms between 8 a.m. Wednesday to 8 a.m. Thursday (Beijing time), the NMC said.

Rainstorms were forecast for south China also during the next three days, while regions in Xinjiang Uygur Autonomous Region in northwest China, Inner Mongolia Autonomous Region in the north, and northeastern China would also experience rainfalls, it said.

The observatory warned local authorities in south China, especially in the flood-battered regions, to get prepared for possible floods and geological disasters.

In Fujian, heavy rains have triggered landslides and flash floods, which engulfed two vehicles in Nanping City and left at least six people dead as of Tuesday.

China's Office of State Flood Control and Drought Relief Headquarters has dispatched work teams to the southern provinces of Hunan, Fujian and Guangxi and to Xinjiang after heavy rains hit the regions.
