At the Forum "Improving community capacity in disaster prevention in the Mekong Delta region" held in Can Tho City on November 29, Ms. Nguyen Thanh Hoa (Climate Forecast Department, National Center for Hydro-Meteorological Forecasting) provided information on forecasting natural disaster trends in the Mekong Delta region from December 2024 to May 2025.
Accordingly, the weather in the next 3 months may lean towards La Nina, and by March 2025, this phenomenon will end.
Also during this period, there may be unseasonal rain in the Mekong Delta, with rainfall possibly higher than the average of many years. However, since this is the end of the dry season, the increase in rainfall is not significant.
Analyzing further the rainfall situation in the Southern region, Ms. Thanh Hoa said that rainfall may increase in December 2024, with total rainfall 10 - 30mm higher than the average of many years, then gradually decrease.
The rainy season in the Mekong Delta is tending to end later. It is now the end of November, but according to the perception, the southwestern region has not yet entered the dry season.
Also within the next 6 months, the total flow of the Mekong River to the Mekong Delta will be 5 - 15% lower than the average of many years.
Representatives of the National Center for Hydro-Meteorological Forecasting predict that the water level in the Mekong River upstream will gradually decrease and will be 0.1-0.2m lower than the average of many years. However, the saline intrusion in the 2024-2025 dry season will be higher than average, not as severe as the dry seasons of 2015-2016 and 2019-2020.
