Early on 12/9, a low-pressure area located 150 km southwest of the Hoang Sa special zone intensified into a tropical depression. It currently has maximum winds of 49 km/h, force 6, gusting to force 8, and is moving northwest at 10 km/h.

By 4h tomorrow, the tropical depression is expected to be over the sea area between Hue City and Da Nang City, approximately 120 km east-northeast of Da Nang City, maintaining its force 6 winds, gusting to force 8.

Heavy rainfall is anticipated across various regions due to the tropical depression and a tropical convergence zone. From early morning through the night of 12/9, areas from Ha Tinh to northern Quang Tri will experience widespread rainfall of 40-80 mm, with isolated areas receiving over 150 mm. Southern Quang Tri to Quang Ngai can expect 80-150 mm, with isolated areas exceeding 250 mm.

Heavy rain will persist throughout 13/9 from southern Nghe An to Da Nang City, with common accumulations of 80-180 mm and isolated areas exceeding 300 mm. Thanh Hoa to northern Nghe An and eastern Quang Ngai will see 30-70 mm of rain, with isolated areas over 120 mm. Meteorological agencies warn of intense rainfall exceeding 100 mm within 3 hours.

Additionally, on 12/9, eastern Gia Lai to Lam Dong provinces, the Central Highlands, and the Southern region will receive 20-40 mm of rain, with isolated areas exceeding 80 mm.

By 4h on 14/9, the tropical depression will be over the coastal waters from Ha Tinh to Hue City, continuing its west-northwest trajectory before gradually weakening into a low-pressure area. International meteorological agencies have not yet issued forecasts for this tropical depression.

At sea, the western Hoang Sa special zone and the waters from Ha Tinh to Quang Ngai will experience strong winds of force 6, gusting to force 8, with waves 2-4 m high, leading to rough seas. Vessels operating in the danger zone are likely to be affected by thunderstorms, whirlwinds, strong winds, and high waves.

The National Steering Committee for Civil Defense urged localities to closely monitor heavy rain, floods, inundation, flash floods, and landslides to promptly warn residents. Local authorities are instructed to review and proactively relocate people from high-risk areas to safety, clear waterways, and prepare support forces as needed. They are also required to control traffic in areas with deep flooding, rapid currents, and landslides; inspect the safety of reservoirs, ongoing construction projects, and critical dikes; increase patrols and watch, and be ready to handle incidents immediately.

In recent history, Typhoon Saudel, which occurred in late August and early September, caused no damage to Vietnam. Although Typhoon Narra did not make landfall in Vietnam, its circulation and low-pressure trough brought heavy rain and thunderstorms, resulting in human and material losses.
