New Tropical Storm Forms in South China Sea - Northern Vietnam Braces for Heavy Rains

CaliToday (07/9/2025): A tropical depression churning in the South China Sea (known as the East Sea in Vietnam) has officially intensified into a tropical storm, meteorological agencies confirmed this morning. The newly formed system is currently on a trajectory that is expected to make landfall on the southern coast of China on Monday, September 8th.

While the storm is not forecast to directly hit Vietnam, its powerful outer bands and subsequent atmospheric circulation are expected to bring significant rainfall to the country's northern mountainous regions in the coming days.

According to Vietnam's National Center for Hydro-Meteorological Forecasting (NCHMF), the storm's development from a tropical depression was marked by a more organized structure and an increase in sustained wind speeds. The system is currently moving in a northwesterly direction across the South China Sea.

The primary impact on Vietnam will be indirect but potentially severe for its northern provinces. The "hoàn lưu" (remnants or circulation) of the storm is predicted to draw in moisture, leading to heavy and sustained downpours. Areas most at risk include provinces such as Hà Giang, Lào Cai, Lai Châu, and Điện Biên, which are already vulnerable to weather-related natural disasters.

Authorities are issuing warnings about the heightened risk of flash floods in low-lying areas and dangerous landslides in the rugged, mountainous terrain. Local disaster management teams have been put on alert, and residents in high-risk zones are being advised to monitor weather updates closely and prepare for potential evacuations if conditions worsen.

Fishermen and vessels at sea have also been warned to avoid the northern part of the South China Sea and to seek safe harbor until the storm has passed.

Officials will continue to track the storm's path and intensity, providing further updates as it approaches its projected landfall in China and as its effects begin to be felt in Northern Vietnam.
