Weather experts expect the southern region to  experience less drought and salinity and more unseasonal rain during this year’s dry season.

They say that the region is an area affected by the neutral phase, a transit stage between El Nino and La Nina.

Nguyễn Kiệt, head of the Forecasting Office under the Southern Regional Hydrometeorological Centre, said Việt Nam and the southern region in particular have experienced the longest El Nino phenomenon in history, from late 2014 to early 2016.

In the dry seasons of 2015 and 2016, severe salinity and drought caused heavy damage, especially in the Mekong Delta.

During the neutral phase, rainfall is high and there are frequent unseasonal downpours.

Kiệt said that between January and March 2016, the southern region saw no unseasonal rain, but in January and February this year, provinces from Bình Phước to Cà Mau experienced rainfall of about 100mm.

Out of season rains are forecast for March and April, but on a smaller scale.

Meanwhile, in the Mekong Delta region, the level was 22.9 grams per litre at Gành Hào River in Cà Mau.
