Heavy rainfall and strong winds prompted flood alerts and more than 1,000 flight cancellations across China on Monday, even as Typhoon Dolphin weakened.

China's National Meteorological Centre (NMC) issued its least severe typhoon alert on Monday morning as the storm lost power after making landfall in China's Zhejiang Province on Sunday.

Despite the weaker storm, the NMC warned that parts of east and central China will continue to receive heavy rainfall. Authorities issued their most severe flash flood alert for parts of eastern and southern Zhejiang on Monday, state news broadcaster CCTV reported.

Five districts in Beijing are also under red alerts for heavy rainfall on Monday, with risks of landslides and flooding.

The storm had already forced over 300,000 people in eastern China to preemptively relocate, while bringing heavy rainfall to northern Taiwan over the weekend. In Shanghai, authorities evacuated more than 30,000 people out of high-risk areas. Overall, some one million people have been told to seek shelter.
