A tropical depression has formed over the East Sea, with maximum winds of 49 km/h, classified as a level 6 storm with gusts up to level 8. The depression is moving towards central Vietnam, forecasted to cause significant rainfall in areas from Ha Tinh to Quang Ngai, with some locations expecting over 300 mm of rain on September 13.

As of early September 12, the depression was located approximately 150 km southwest of the Paracel Islands, intensifying as it moved northwest at a speed of 10 km/h. By 4 AM the following day, it is predicted to be situated over the waters between Hue and Da Nang, about 120 km east-northeast of Da Nang, maintaining its strength at level 6 with gusts of level 8.

By September 14, the tropical depression is expected to be near the coastal waters from Ha Tinh to Hue, continuing its northwest trajectory before gradually weakening into a low-pressure area. International meteorological agencies have yet to provide assessments for this tropical depression.

The depression, combined with a tropical convergence zone, is likely to bring widespread rainfall from early morning to night on September 12, with expected totals of 40-80 mm in the Ha Tinh to northern Quang Tri areas, and localized amounts exceeding 150 mm. In the southern Quang Tri to Quang Ngai regions, rainfall is anticipated to be between 80-150 mm, with some areas receiving over 250 mm. On September 13, heavy rains are expected to continue from southern Nghe An to Da Nang, with common totals of 80-180 mm and isolated areas exceeding 300 mm.

In addition, rainfall of 30-70 mm is predicted for Thanh Hoa to northern Nghe An and eastern Quang Ngai, with localized totals above 120 mm. Meteorological authorities have warned of the risk of rainfall exceeding 100 mm within three hours.

On the sea, the western waters of the Paracel Islands and the waters from Ha Tinh to Quang Ngai will experience strong winds of level 6, gusting to level 8, with wave heights of 2-4 meters, leading to rough seas. Vessels operating in these dangerous areas may face severe thunderstorms, strong winds, and large waves.

The National Civil Defense Steering Committee has urged localities to closely monitor the heavy rainfall, flooding, and landslides to timely warn residents. They are advised to review and proactively relocate people in high-risk areas to safety, clear drainage systems, and prepare support forces as necessary. Local authorities are required to control traffic in areas with deep flooding and swift currents, check the safety of reservoirs and construction sites, and enhance patrols and monitoring to promptly handle emergencies.

Recent storms, including Typhoon Saudel at the end of August and early September, did not cause damage to Vietnam. Although Typhoon Narra did not make landfall, its remnants and low-pressure troughs resulted in heavy rainfall and thunderstorms, causing damage to both life and property.
