Forecast map of saline intrusion in Mekong Delta region.

According to the National Center of Hydrometeorological Forecasting, from today, 11/5 to 20/5, saline intrusion in the No. 1 rice bowl in Vietnam (Mekong Delta) tends to decrease gradually at the beginning of the week, then increase slightly at the end of the week. During this period, the Southern region is likely to have scattered thunderstorms in the evening, while thunderstorms and strong winds may occur. However, the rain is unevenly distributed and takes place in a short time with the total rainfall ranging from 20-50mm, some places are higher. The highest temperature in the South in the next 10 days is commonly in the range of 34-37 degrees Celsius.

Regarding hydrological developments, the water level of stations on the Mekong mainstream in the coming days varies slowly, at the same level and higher than the average of many years from 0.1-0.3m. The water level on Tien and Hau rivers rises in the last days. In particular, the highest water level in Tan Chau is 1.25m; in Chau Doc 1.40m, higher than the average of the same period of the year from 0.25-0.4m. The salinity depth of 1g / l in this period in Vam Co Dong and Vam Co Tay rivers has 90-130km saline intrusion range; Cua Tieu and Cua Dai rivers of 55-70km; Ham Luong river 65-80km; Hau and Co Chien rivers 45-50km; Cai Lon river 52-58km. Similarly, the salinity depth of 4g / l during this period in Vam Co Dong and Vam Co Tay rivers has a saline intrusion range of 80-120km; Cua Tieu and Cua Dai rivers of 50-55km; Co Chien and Hau rivers 35-42km; Cai Lon river 45-52km ... The level of disaster risk from saline intrusion in the Mekong Delta during this period is at level 1-2. With the above developments, the meteorological agency forecasts that saline intrusion in the Mekong Delta is tending to decrease but still remains high. Therefore, localities before taking fresh water, watering crops and fruit trees need to closely monitor salinity levels.
