Inundation and flash flood have been forecast to occur in northern Vietnam over the next days under the influence of a low-pressure zone, the national weather forecaster said Sunday.

The low-pressure area is expected to bring downpours and strong gusts in northern localities, including Hanoi, and north-central provinces from Thanh Hoa to Thua Thien- Hue, until Wednesday.

As of Sunday morning, the weather system was located at the southern part of the Gulf of Tokin, the National Center for Hydro-meteorological Forecasting reported, adding that it could evolve into a tropical depression.

The tropical depression may make landfall between Thanh Hoa and Ha Tinh Provinces, the center added.

Prolonged downpours will lead to high risks of inundation in multiple provinces and cities as well as flash floods in mountainous areas.

In Hanoi, torrential rain accompanied by strong wind is likely to cause flooding on various streets in such districts as Dong Da, Ba Dinh, Hoan Kiem, and Tay Ho.

In late June, serious floods and landslides brought about by heavy downpours killed 23 people and left many missing in Lai Chau and Ha Giang Provinces in northern Vietnam.

Countless houses, streets, and farms were heavily damaged, with losses estimated at VND450 billion (US$19.8 million).

Meanwhile, southern Vietnam has recently been affected by an active southwest monsoon, thus rainfall will continue in the upcoming days.

Showers are expected to occur mainly on the evening and at night.

Average temperature in the region ranges from 22 to 32 degrees Celsius.

Rough seas and waves as high as two to four meters are forecast in the southern part of the East Vietnam Sea.
