Southern Vietnam Faces Severe Flooding Risk as Heavy Rains Combine with Spring Tides

Southern Vietnam is facing a high risk of severe flooding from September 23rd onwards, as heavy rainfall coincides with the spring tide associated with the full moon on the 15th of the eighth lunar month. The National Center for Hydro-Meteorological Forecasting has warned that this combination of weather phenomena will lead to rising river levels, particularly in areas around Ho Chi Minh City, exacerbating urban inundation. Forecasts indicate that from September 23rd to 24th, the central coastal regions (from Hue to Da Nang, eastern Quang Ngai province, etc.) will experience extremely heavy rainfall, with localized amounts exceeding 250mm. Lam Dong, Khanh Hoa, and southern provinces are expected to receive moderate to heavy rain, ranging from 40-80mm, and in some places, over 150mm. The potential for rainfall intensity exceeding 100mm within a three-hour period has also been highlighted. The heavy rainfall in the southern region is projected to continue until September 24th, after which it is expected to gradually decrease but persist. Compounding this, the current period aligns with the full moon tide of the eighth lunar month, naturally raising river levels. This synergy between heavy rain and high tides significantly increases the risk of severe flooding. Ho Chi Minh City is also anticipating similar weather conditions, raising concerns about urban flooding impacts. At sea, rain and thunderstorms are forecast for areas from the Tonkin Gulf to the South China Sea. These regions may experience lightning, strong gusts (level 7-8), and waves exceeding 2 meters, necessitating urgent measures for maritime safety. Vietnamese meteorological authorities are urging residents to closely monitor the latest weather updates and remain vigilant against flooding and natural disasters. Such natural events can impact Vietnam's economic activities and infrastructure, with potential disruptions to transportation networks and daily life, especially in urban centers.
