Five to seven storms and tropical depressions are forecast to enter the East Vietnam Sea between the second half of August and November, according to the national weather center.
Among them, up to three might make landfall in Vietnam during this period.
Hoang Phuc Lam, deputy director of the National Center for Hydro-meteorological Forecasting, said that El Nino, a climate pattern that originates in the Pacific Ocean along the equator, has impacted the weather.
El Nino is forecast to have an 85-90 percent probability of persisting for the next three months.
Before September 11, one or two storms might rip through the East Vietnam Sea, bringing rains and strong winds to the northern and central regions.
Lam also said that heatwaves will continue in central Vietnam in the second half of August.
The central region will see scorching weather weaken in September.
The average temperature nationwide in September and October is forecast to be 0.5-1 degree Celsius higher than that in previous years.
In September, the northern region might experience higher rainfall than that in many years earlier.
In the central region, the rain volume in October will be 10-25 percent smaller than the average level of the preceding years.
In the next three months, the southern and Central Highlands regions will be hit by more rains compared to previous years.
“Floods triggered by downpours might batter big cities, while flash floods and landslides are expected to occur in the northern mountainous areas,” Lam said.
