Northern and northern central regions of Vietnam will experience hot and muggy weather for the first few days of this week, said the National Hydro Meteorological Forecasting Center.
Meanwhile, the southern and Central Highlands regions will see showers with temperatures hovering around 30-33 degrees Celsius in some areas.
The southern central region alone might experience heavy rains, triggered by an inter-tropical convergence zone, in the next four to five days.
Over the last few days, the sweltering weather has already covered northern provinces as a westerly hot low-pressure system has returned.
