Northern Vietnam can expect a cool week while sunny days are unlikely in central and southern regions.
Thanks to a series of intense cold air masses, towns and cities in the north, especially mountainous areas, are forecast to experience a drop in temperature overnight starting from Tuesday, Le Thi Xuan Lan, a Ho Chi Minh City-based weather pundit, has predicted.
In the second half of the week, large-scale rain is likely, mainly in northern deltas and coastal areas.
As a trough skirts the south-central region, towns and cities in there can anticipate cooler weather with drizzle in the evening in the first few days of the week.
Conditions are likely to worsen from midweek onwards as the trough heads north, combining with cold air masses there.
Under the influence of southwesterly winds and a trough weakened from the storm Aere, the Central Highlands and the southern region can anticipate a gloomy week with prolonged rain and overnight precipitation.
According to the National Center for Hydro-Meteorological Forecasting, the tempest, which formed on Thursday, was downgraded to a depression on Monday morning, with winds between 50 and 60 kph.
Over the next 24 hours, the depression is likely to weaken to a trough while traveling west-southwestwards, the weather center forecast.
