A low pressure trough currently operating in southern China is tending to move towards the mainland of northern Vietnam.
From the evening of May 28, the rainy area due to the influence of the low pressure groove will start from the mountainous areas of the Northern provinces, then spread to the midland and plain, coastal areas.
By around May 29, the heavy rain will expand to the North Central provinces.
