Typhoon Dolphin Closes China's Largest Refueling Hub, Cancels 1,384 Flights

Extreme weather has pummeled China this summer. Heavy rain since early July has triggered flash flooding and crop damage. President Xi Jinping last month called for "all-out" disaster relief after deadly storms hit parts of the country.

Rail operator China Railway Shanghai Group said it suspended some services across the Yangtze River Delta region starting Sunday, with some route disruptions extending through Thursday. Ferry services in Shanghai were also halted, state broadcaster China Central Television reported.

The meteorological authority forecast heavy to torrential rain from Sunday to Wednesday across Fujian, Zhejiang, Shanghai, Jiangsu, Hebei, Beijing, and Tianjin.

The red alert follows Typhoon Noul in late July, which also forced widespread evacuations and port closures. The summer's repeated weather shocks have heaped pressure on supply chains and infrastructure.
