Northern Vietnam Braces for Heavy Rains, Flood Risks Escalate

Northern and north-central Vietnam are facing significant flood risks following torrential rains on September 15, attributed to the influence of a tropical depression. The National Hydro-Meteorological Forecasting Center reported that from the evening of September 14 through September 16, the northern plains, Bac Ninh province, southern Phu Tho province, and Thanh Hoa province are expected to receive 100-250mm of rain, with some areas exceeding 400mm. Hung Yen province, Ninh Binh province, southern Phu Tho, and Thanh Hoa could see 200-400mm, and in some locations, over 550mm. Lang Son province, northern Phu Tho, southern Thai Nguyen, Tuyen Quang, Son La, Lao Cai, and Nghe An province are forecast to experience moderate to heavy rainfall and thunderstorms, with some areas receiving very heavy rain, ranging from 80-170mm, and locally over 300mm. The risk of intense rainfall exceeding 100mm within a three-hour period is high, accompanied by potential tornadoes, lightning, hail, and strong gusts. This heavy rainfall is expected to cause river rises in Bac Bo, Thanh Hoa, and Nghe An provinces. Specifically, the Boi River in Phu Tho, Hoang Long River in Ninh Binh, and the upper reaches of the Buoi, Ma, and Chu rivers in Thanh Hoa could reach alert levels 1 to 2, or even exceed level 2. The upper reaches of the Ca River in Nghe An are also predicted to rise above alert level 1. Consequently, the risk of flooding in low-lying areas along rivers and urban centers, as well as landslides on steep slopes in Phu Tho, Ninh Binh, Thanh Hoa, and Nghe An provinces, is exceptionally high. In contrast, rainfall in the southern region is expected to decrease, with more sunshine during the day. Maximum temperatures are forecast to range from 31-34°C, with some areas exceeding 34°C. Scattered showers and thunderstorms are anticipated in the afternoons, primarily affecting coastal areas of the Mekong Delta, northern Tay Ninh, Dong Nai, and western Lam Dong. In the capital, Hanoi, heavy to very heavy rain and thunderstorms are expected, with temperatures ranging from 25-27°C during the day and 23-25°C at night. Vietnam's ongoing economic development and infrastructure projects are increasingly challenged by the frequency of extreme weather events, highlighting the nation's vulnerability. While the one-party system may facilitate swift disaster response, long-term adaptation strategies and sustainable development plans to address climate change are becoming increasingly critical.
