Typhoon Co-may is expected to make a second landfall along Shanghai’s southern coast on Wednesday night, after first hitting Zhejiang between Zhoushan and Ningbo earlier in the day.
The storm is gaining strength over the East China Sea and is forecast to bring heavy rain, strong winds, and widespread disruption to Shanghai starting Tuesday night. Rainfall will intensify overnight, with the heaviest downpours expected through Wednesday. Some areas may see up to 220 mm of rain. Inland wind gusts could reach levels 7–8, with coastal and offshore areas seeing gusts up to level 11.
Flights and trains have already been affected. Dozens of flights at Pudong and Hongqiao airports were delayed or canceled, mainly on southern routes. China Eastern Airlines is offering free ticket changes and refunds. Several train services have been suspended or shortened, including routes on the Hangzhou-Shenzhen line.
Tourist sites such as Suzhou Creek cruise boats, Bihaijinsha scenic area and Fisherman’s Wharf in coastal Fengxian District are closed.
In Fengxian and Chongming, inspections are underway on infrastructure, ferry services are suspended, and emergency crews have been deployed.
A Level IV emergency response is in effect for Shanghai, Zhejiang, and Jiangsu. Local authorities have lowered water levels in rivers and canals, prepared evacuation plans, and placed emergency teams on standby.
Co-may is expected to weaken after landfall but may continue to bring unsettled weather to the region through the weekend.
