Four Typhoons Active Simultaneously in Western Pacific and South China Sea, Threatening South and East China Coastlines

Four distinct typhoons—Saudel, Zitan, Jelawat, and Atsani—are currently active simultaneously across the Western Pacific and the South China Sea. Weather experts warn that their successive movements will bring prolonged heavy rain and powerful winds to China’s southern and eastern coastal regions, significantly elevating disaster risks.

The national weather agency noted complex interactions among the storms. Typhoon Zitan and Typhoon Jelawat are exhibiting a binary interaction (Fujiwhara effect), while Saudel and Atsani are also influencing each other's trajectories. Forecasters emphasized that these dynamics do not simply mean the typhoons will collide or merge into a stronger storm, but rather complicate their motion paths.

Typhoon Zitan is currently hovering over the Gulf of Tonkin with minimal movement. Analysts project it will continue lingering near the area, delivering heavy precipitation to western Guangdong and southern Guangxi, with impacts on Guangxi expected to persist through August 28. Prolonged rain over identical geographic zones drastically increases the likelihood of secondary disasters due to ground saturation.

Meanwhile, Typhoon Saudel presents dual potential tracks: it may either head toward the coastal border between central-southern Zhejiang and Fujian after entering the East China Sea, or dip southward across Taiwan before approaching central-southern Fujian. Regardless of its exact path, severe wind and rain remain imminent for China's southeastern seaboard.

Across southern coastal provinces—including Hainan, Guangxi, Guangdong, Fujian, Taiwan, and southeastern Zhejiang—heavy to torrential downpours are forecast, with localized spots facing extreme rainstorms. Inland areas such as Hunan, Jiangxi, and Yunnan will also experience scattered intense rainfall.

In contrast to the south, northern China is experiencing frequent but localized precipitation events accompanied by severe convective weather, including thunderstorms, severe gales, and hail, which are expected to continue through late August.

Meteorologists urge coastal regions in South and East China to prepare for flash floods, urban flooding, and geological hazards caused by overlapping rainfall and upstream runoff. Residents in affected areas are advised to stay updated on official weather alerts and adjust travel plans accordingly.
