At least 15 people were killed last week and new low pressure system across region will bring more disruption

Record-breaking rains that have battered parts of China and east Asia in the last week are expected to worsen, with authorities warning of an increased risk of floods.

In the first week of China’s flood season, extreme rainfalls have caused floods and landslides, destroyed roads and infrastructure, and led to the deaths of at least 15 people. Floods, landslides and disruptions to water and electricity were reported in Shaoguan, in northern Guangdong province, and more than 800,000 people in Jiangxi were reportedly affected by torrential rains that have so far hit 80 of the province’s counties and damaged more than 76,000 hectares (188,000 acres) of cropland.
