The Southern Hydro-meteorological Forecast Center said a cold air stream from the north is moving in a south-easterly direction and will affect the entire area of central Viet Nam but temperatures in southern provinces will be very hot.
Variable weather conditions will occur in the central region with hail and whirlwinds possible. Due to the influence of the cold air stream, the Tonkin Gulf will experience rough seas with north-easterly winds gusting to category 6-7 levels.
Temperatures in the southern parts of Viet Nam are predicted to increase and no rain is forecast. High temperatures are also predicted to lead to a reduction in the water levels of rivers in the southern provinces of An Giang, Dong Thap and Long An.
