Mekong Delta Faces Flooding Risk as King Tide Peaks Late September; Vinh Long May See Up to 50cm Inundation

Southern Vietnam's Mekong Delta region is facing a heightened risk of flooding as the king tide associated with the Lunar August 15th festival is forecast to peak from late September to early October. Provinces like Vinh Long and Tra Vinh, particularly their low-lying riverside areas, are expected to experience inundations of up to 50cm, potentially impacting local communities and infrastructure. According to the Vinh Long provincial Department of Meteorology and Hydrology, water levels at the My Thuan station are projected to reach 215cm between September 29th and October 1st. This level is 35cm above alarm level III and approximately 4cm higher than the tide observed in mid-September. Similar high water levels are anticipated at the Cho Lach station, potentially reaching 207cm (17cm above alarm level III), Tra Vinh at 202cm (12cm above alarm level III), and Cau Quan at 207cm (7cm above alarm level III). The rising tides, combined with upstream floodwaters, rainfall, and other factors, increase the risk of flooding in areas with poor drainage, low-lying zones, and areas outside protective dikes. Regions along the Tien, Ham Luong, Co Chien, Mang Thit, and Hau rivers, as well as islets and sandbanks, require particular attention. Several key roads in Vinh Long province, including those in Thanh Duc, Phuoc Hau, Long Chau, and Tan Ngai communes, as well as Nguyen Hue, 3 Thang 2, Hung Vuong, Dinh Tien Hoang, Nguyen Trung Truc, Ly Thai To streets, and National Highway 53, are at risk of inundation. Flooding is also anticipated in parts of Cho Lach, Tien Thuy, An Hoi, Mo Cay, Tan Thanh Binh, Long Duc, Hoa Thuan, Nguyet Hoa, and Tra Vinh province. The predicted flood depth ranges from 5cm to 50cm between September 24th and October 2nd. The most severe inundation, with depths of 30cm to 50cm depending on the location, is expected from September 29th to October 1st. The Vinh Long Department of Meteorology and Hydrology has advised local authorities to reinforce dikes, protect fruit orchards, livestock, and aquaculture, and urged residents to elevate their belongings, prepare for transportation disruptions, and guard against landslides. The natural disaster risk level for this king tide event has been assessed as Level 2. These floods could adversely affect the environment and disrupt road transportation and fruit cultivation areas. Vietnam continues to grapple with the impacts of climate change in the Mekong Delta, a vital agricultural hub for the nation.
