Tropical Storm Dolphin has wreaked havoc in eastern China, bringing heavy rainfall and strong winds that have prompted authorities to issue severe flood warnings. The storm made landfall late on Sunday in Yuhuan, Zhejiang province, with maximum sustained winds of 151 kilometers per hour (94mph), triggering the highest weather alert in China. Over a million people have been evacuated from their homes as the National Meteorological Center activated a "red alert" – the highest level in the country’s typhoon warning system. By Monday, Dolphin had weakened into a tropical storm but continued to drench eastern provinces such as Anhui, Jiangsu, and Shandong with torrential rain. The storm is forecast to continue through August 10 across Zhejiang, Shanghai, northern Fujian, northeastern Jiangxi, central and southern Anhui, and much of Jiangsu, with parts of central and eastern Zheijiang expecting up to 500mm (19.7 inches) of rain. Shanghai's two airports have canceled a total of 943 flights due to the typhoon, while authorities urge residents to work from home and avoid going outside where possible. Search and rescue teams are currently searching for a nine-year-old boy who was swept into the sea during the storm in Wenling, Zhejiang. Over 900,000 residents have been relocated in Wenzhou alone, with nearly 100,000 evacuated in Shanghai and another 99,000 in neighboring Fujian province. The strongest typhoon to hit China this year, Dolphin is expected to move deeper inland towards the central provinces of Hubei and Henan in the coming days while also pushing moisture north. Authorities in Beijing have raised warnings for torrential rain and are prepared to activate their flood control response on Tuesday morning as the city braces for significant rainfall from Tuesday until Thursday, with the risk of flash floods and landslides.
