Rescue operations were underway after unseasonably heavy rain caused rivers to overflow, triggering landslides in Yingde city in flood-ravaged Guangdong province, broadcaster CCTV reported on Tuesday.

It comes as the latest figures showed that four people have died as a result of the heavy rain, and 10 others are still missing. Provincial authorities have relocated some 110,000 residents so far.

Rescue and emergency workers were seen tending to stranded residents on rescue boats in residential areas as well as commercial streets, in video aired by CCTV. The broadcaster also reported emergency supplies including food, water and other amenities were being provided.

In one village, farmers stood at a flooded intersection along with belongings they managed to save, including a washing machine.

“Everything's gone, all the seedlings are gone," said Huang Jingrong, 61.

"It's all flooded, flooded beyond repair," he said, estimating his losses at about 100,000 yuan.

Meanwhile, massive flooding has occurred in Beijiang River in the Pearl River basin on Monday due to the continuous heavy rain, according to the Ministry of Water Resources.

Guangdong has been battered by unusually heavy, sustained and widespread rainfall since Thursday, with powerful storms ushering in an earlier-than-normal start to the region's annual flooding season. (Reuters/Xinhua)
