Contiuous strong rain started to hit the central China province on Monday killing six people, the Hunan provincial flood prevention and drought control headquarters said.
As of Saturday, rainstorms have affected about 850,000 people, toppled more than 2,200 homes and forced 14,000 citizens to relocate in Hunan.
Heavy rainfall has also led to the flooding of major reservoirs and rivers.
Rainstorms have affected about 196,800 people in east China's Jiangxi Province, local authorities said Saturday.
As of 11 p.m. Friday, the heavy rain, which started from Tuesday, has battered 26 counties in Jiangxi, the provincial flood prevention and drought control headquarters said.
Local governments have relocated 6,019 residents to avoid potential risks.
The downpours have also damaged or destroyed 202 houses and ruined 16,710 hectares of crops, as well as causing high water levels of rivers and lakes, and several landslides.
Flood prevention authorities in Jiangxi warned of floods on Thursday due to the rising rivers and lakes.
The headquarters also ordered several reservoirs in the province to release water as levels had gone over or were approaching alarm lines because of the heavy rain.
No casualties have been reported as a result of the rainfall in Jiangxi.

TAIPEI - Taipei mayor Hau Lung-bin announced on Saturday the suspension of inter-city exchanges with the Philippines after a Taiwanese fisherman was shot dead by Philippine coast guards at sea.
The Philippines will also not be allowed to take part in Dragon Boat Festival races in Taipei on June 12, Hau said.
Hau condemned the Philippines over the shooting, and called it a violent act to fire upon an unarmed fisherman. He urged the Philippine government to apologize, release investigation reports and hold those responsible to account.
He also advised the Taiwanese authorities to take a hard stance on the Philippines by halting Philippine-bound tourism, suspending labor imports from the country and increasing fishing protection patrols.
The shooting happened on Thursday morning 164 nautical miles southeast of the southernmost tip of Taiwan, according to the island's coast guard authority.
The victim was identified as Hung Shih-Cheng, 65, one of four crew members of the Taiwanese fishing vessel Guang Ta Hsin 28. Hung's body was taken back to Taiwan early Saturday morning.
