According to the National Center for Hydro-Meteorological Forecasting, currently (September 5), the tropical convergence zone has an axis through the northern East Sea connecting with the low pressure area in the sea area east of Luzon Island (Philippines).
At 7:00 a.m. on September 5, the low pressure area was located at about 16.5 - 17.5 degrees north latitude; 121.5 - 122.5 degrees east longitude. The eastern sea area of the northern and central East Sea will have scattered showers and thunderstorms.
It is forecasted that in the next 24 hours, the low pressure area will move westward and tend to strengthen.
Day and night on September 5, the sea area from Lam Dong to Ca Mau, Ca Mau to An Giang, the Gulf of Thailand, the northern East Sea, the central and southern East Sea (including the special areas of Hoang Sa and Truong Sa) will have scattered showers and thunderstorms. During thunderstorms, there is a possibility of tornadoes, strong gusts of wind of level 6 - 7 and waves over 2m high. All ships operating in the above areas are at risk of being affected by tornadoes and strong gusts of wind.
Regarding the trend of marine weather in September, storms, tropical depressions and southwest monsoons can cause strong winds, large waves at sea and affect the activities of ships.
Previously, in August 2025, there were 2 storms and 2 tropical depressions in the East Sea, of which 2 storms and 1 tropical depression in mid-August directly affected our mainland.
Informing about the upcoming natural disaster situation, Mr. Hoang Duc Cuong - Deputy Director of the Department of Hydrometeorology (Ministry of Agriculture and Environment) said that from now until the end of 2025, it is necessary to pay attention to some main types of storms, floods and cold air activities.
"Regarding storms, from now until the end of 2025, there may be 5-7 storms or tropical depressions in the East Sea. It is possible that half of them will affect the mainland of Vietnam" - Mr. Cuong said.
According to the representative of the Department of Hydrometeorology, according to the law of the storm season, storms and tropical depressions at the end of the season often affect the area from the Central region to the south. In addition, this year, cold air is forecast to arrive early.
Mr. Cuong commented that this further clarifies the warning signal for a complex flood season.
"The activity of storms and tropical depressions combined with cold air can increase the possibility of high-intensity rain in a short time, leading to the risk of urban flooding, industrial parks, flash floods, and landslides in the mountainous areas west of the Central region" - Mr. Cuong analyzed.
Previously, the notable storm was storm No. 5, which was assessed as unusual, formed in the East Sea and strengthened very quickly, with a short life cycle of only about 3 days.
The maximum intensity of the storm before making landfall will reach level 14, gusting to level 17 - equivalent to Typhoon Yagi (No. 3, 2024) and stronger than Typhoon Doksuri (No. 10, 2017). The storm circulation is wide, covering almost the entire East Sea, causing widespread rain on land.
According to the Department of Dyke Management and Natural Disaster Prevention (Ministry of Agriculture and Environment), the 5th storm and floods after the recent storm caused about VND2,900 billion in damage to the North Central and Northern provinces, concentrated in Nghe An, Thanh Hoa, and Ha Tinh provinces.
