Torrential rain will continue to ravage the Pearl and Yangtze river delta regions over the weekend, weather officials said on Friday.

Yang Minyi, from the Guangdong flood, drought and wind prevention office, said the rains have already killed at least 10 people with several others missing.

"Typhoon Fengshen has left Guangdong but the downpours remain," Lin Liangxun, from the Guangdong provincial observatory, said.
