Typhoon Co-May has brought powerful winds and torrential rain to eastern China, prompting mass evacuations and emergency measures across multiple provinces. The storm made its first landfall in Zhejiang Province around 4:30 a.m. Wednesday and struck Shanghai later that same day, according to the Shanghai Central Meteorological Observatory.
As the typhoon neared Shanghai, authorities undertook one of the city’s largest evacuation efforts in recent years. By 10:00 a.m. Wednesday, nearly 282,800 people had been relocated from vulnerable areas, achieving what state broadcaster CCTV described as the full evacuation of all individuals deemed at risk.

In response to escalating weather conditions, the Shanghai Central Meteorological Observatory upgraded its rainstorm warning from yellow to orange, the second-highest level in the country’s alert system. Live footage from the coast showed waves breaching seawalls and walkways, while residents in Ningbo, Zhejiang Province, navigated through ankle-deep floodwaters in city streets.

Meanwhile, Taihu Lake—one of China’s largest freshwater lakes—has reached its flood warning level of 3.8 meters. Authorities from the Ministry of Water Resources have launched preventive flood management across the lake basin, which spans Jiangsu and Zhejiang provinces.
In Anhui Province, widespread rainfall arrived Friday following the storm’s movement inland Thursday night. Cities including Hefei, Xuancheng, and Tonglin implemented emergency responses such as halting outdoor operations, closing tourist destinations, and securing vulnerable infrastructure.
Local governments in mountainous areas have focused on flood-prone zones, carrying out inspections and evacuating residents from high-risk locations. These efforts are part of a coordinated disaster prevention strategy now active throughout the eastern region.
Separately, as Typhoon Co-May was unfolding, China briefly issued a tsunami warning along its eastern coastline following a magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula. The warning was later lifted without incident, though it added further tension to a region already bracing for extreme weather.
Authorities continue to monitor the storm’s path and are urging the public to stay indoors and follow all official directives as cleanup and recovery efforts begin.
