Rain at under 5mm is forecast for some areas upstream the Mekong River, while there will be no rain in downstream areas and the southern region as a whole.
Water level in upper Mekong River is expected to change little at a level 0.5-2m higher than the average for many years, while the level downstream will be 0.02-0.2m higher than average.
Water flows recorded in the two main tributaries of Mekong River are rising at slow pace, and expected to reach the highest volume of 3,200-3,500 cu.m per second at Tan Chau gauging station on Tien River on April 4 or 5 and 600-750 cu.m per second at Chau Doc gauging station on Hau River.
Meanwhile, the highest tidal level measured at Sai Gon and Dinh An gauding stations are forecast to be higher than the level for the same period last year by 20-30cm.
Rainstorm is possible to occur in some northern areas of the Central Highlands on April 4 and 5 with rainfall ranging from 5-15mm.
Water levels on rivers in the south central region and Central Highlands will remain at low levels with water flows reducing by 50-70 percent from many-year average.-VNA
