Typhoon Co-May, the eighth typhoon of the year, made landfall on Zhujiajian Island, Zhoushan City, in east China's Zhejiang Province, at around 4:30 a.m. on Wednesday. Upon landfall, maximum wind speeds near the center reached 23 meters per second (Category 9), and the minimum central pressure was 975 hectopascals (hPa), according to China's National Meteorological Center (NMC).

The NMC forecasts that Co-May will continue moving northwest at a speed of 10–15 kilometers per hour (km/h) and intensify slightly. A second landfall is expected later today between Ningbo in east China's Zhejiang Province and Qidong in east China's Jiangsu Province, where wind speeds could reach 23–28 meters per second (Category 9–10, equivalent to a tropical storm or strong tropical storm). After making landfall, the typhoon's intensity is expected to gradually weaken.
