Heavy rains will cover Vietnam’s southern, south-central, and Central Highlands regions in the days to come with extremely high rainfall predicted, the central weather forecast agency said on Sunday.
Moderate to torrential rains, possible along with thunderstorms, will strike these regions during the next four days, the National Center for Hydrometeorological Forecasting reported.
In the south-central and southern regions, precipitation may range between 150 and 300 millimeters while in the Central Highlands, it may hover from 200 to 450 millimeters.
Such a rainy weather pattern comes from a combination of the low-pressure trough whose axis is moving north and the southwest monsoon that is operating strongly, the center explained.
On Sunday night, moderate to heavy rains hit many mountainous and midland areas in northern provinces with rainfall measured at 129 millimeters in Phu Tho, 104 millimeters in Tuyen Quang, and 85 millimeters in Yen Bai.
Due to the combination of the wind convergence at a 1,500-meter elevation and the low-pressure running through northern mountainous and midland provinces, moderate to heavy rains, along with thunderstorms, are in the forecast there on Monday, with rainfall of up to 100 millimeters.
In Hanoi, showers and thunderstorms, with moderate and heavy rains, may also occur on Monday.
Flash floods, landslides, and flooding are likely to strike mountainous provinces, the center warned.
In coping with unfavorable weather conditions in the coming days, provincial and municipal authorities should arrange fully-equipped forces at main traffic points, especially at tunnels, spillways and swift-flowing waters, to ensure smooth and safe traffic, the Central Steering Committee for Natural Disaster Prevention and Control required.
Local authorities should also prepare plans to ensure safety for vulnerable residential areas, the agency said.
