3 storms may hit East Vietnam Sea in September

The forecast aligns with the long-term average of around 2.4 such systems in September.

Rainfall is expected to be 10-25 percent higher than normal in the northern delta and from Thanh Hoa to Gia Lai Provinces.

Heavy and widespread rains are forecast for the central provinces from Thanh Hoa to Quang Ngai, while other regions will likely see frequent showers and thunderstorms.

The national weather agency also warned of dangerous conditions including whirlwinds, lightning, hail, and strong wind gusts.

"Storms, tropical depressions, and the southwest monsoon will generate strong winds and high waves, threatening marine operations. Heavy rainfall may trigger flash floods, landslides, and flooding in low-lying areas, posing risks to public health and daily life," the agency stated.

Localized heavy downpours are especially likely in Thanh Hoa to Hue and along the south-central coast during the first half of the month.

While nationwide temperatures are expected to stay near historical averages, the Central Highlands and southern Vietnam may see temperatures that are 0.5-1 degree Celsius higher.

In August, two storms—Kajiki and Nongfa—along with two tropical depressions entered the East Vietnam Sea.

Both storms and one tropical depression made landfall in Vietnam.

Kajiki, the fifth named storm of the year in the region, caused widespread damage in Ha Tinh and Nghe An Provinces, where about 30,000 homes lost roofs and approximately 160,000 trees were uprooted.
