After a sudden resurgence over the Pacific, Typhoon Co-may is now steering toward eastern China – putting Shanghai and surrounding coastal provinces in line for strong winds, heavy rainfall and rising seas.

Once weakened into a low-pressure system, Co-may redeveloped late on Sunday (July 27) to the east of the Ryukyu Islands.

The China Meteorological Administration confirmed early on Monday morning that the storm has regained typhoon status and will continue to be identified as Typhoon Co-may, maintaining its original name and number (2508).

As of 8am on Monday, the typhoon's center was located about 700 kilometers southeast of Zhoushan, Zhejiang Province. With maximum sustained winds reaching Level 8 (18 meters per second) and a central pressure of 992 hPa, Co-may's wind field stretches across a radius of 200 to 300 kilometers, already stirring up rough seas and blustery conditions across the region.

Forecasters predict that Co-may will move in a northwesterly direction at a pace of 15 to 20 kilometers per hour, gradually strengthening as it enters the eastern part of the East China Sea.

The storm is expected to close in on coastal areas between northern Zhejiang and southern Jiangsu, potentially brushing the shores of Shanghai in the coming days.

Heavy rain looms

Starting Monday night, rain will intensify across the city, transitioning into overcast skies with intermittent showers. Some areas may accumulate significant rainfall, reaching heavy rain levels.

Monday's high is expected to reach 30 degrees Celsius, but the combination of moisture and warmth will bring a muggy, uncomfortable feel.

From the morning of Monday to the morning of Tuesday, much of the East China Sea, the waters east of Taiwan, Hangzhou Bay, the Yangtze River Estuary, and the coastal zones of Shanghai, southern Jiangsu and Zhejiang will be affected by winds of Level 7 to 8, with gusts reaching Level 9 to 10. In some sea areas directly in Co-may's path, winds may intensify to Level 9, with gusts up to Level 11.

The storm is also expected to unleash significant rainfall. Heavy to torrential rain is forecast for parts of eastern Taiwan and eastern Zhejiang, with particularly intense downpours of 100 to 200 millimeters possible in western Taiwan. Scattered storms are likely across eastern and southern Fujian, much of Guangdong, and southern regions of Jiangxi and Hunan, raising concerns about localized flooding and landslides.

Damp days to follow

Looking ahead, once Co-may moves away later this week, atmospheric patterns are expected to shift, bringing more stable but still humid weather to Shanghai. The city will see mostly cloudy skies with occasional short-lived showers. Daytime highs will stay between 29 and 33 degrees, and the sultry, damp air will continue to dominate – making the end of July feel distinctly tropical.

As Co-may churns toward China's eastern coast, authorities urge residents and travelers in the affected areas to stay informed, prepare for severe weather and heed all safety advisories. With wind, rain and waves intensifying, the coming days could prove challenging for millions in the storm's path.
