A low pressure area in the East Vietnam Sea is forecast to slowly move west-northwest and pick up strength before entering central Vietnamese localities over the next 24 hours, further complicating flooding in the region, according to the national weather center.

The low pressure area was spotted near Vietnam's Hoang Sa (Paracel) archipelago off central Da Nang City at 7:00 am on Sunday, said the National Center for Hydro-meteorological Forecasting.

The inclement weather will likely bring showers and thunderstorms to the waters of the central localities from Quang Tri Province to Quang Ngai Province, from south-central Binh Thuan Province to southern Ca Mau Province throughout Sunday.

The northern part of the Gulf of Tonkin, the waters from Binh Dinh Province to Ninh Thuan Province in central Vietnam, and from Ca Mau Province to Kien Giang Province in the southern region are expected to experience similar foul weather during the said period.

Whirlwinds and gusts could also lash these areas when it rains, the national weather center warned.

Powerful winds, rough seas, and waves of three meters high may hit the northern waters of the East Vietnam Sea on Sunday.

All fishing vessels and other activities taking place in these waters could feel the impact of whirlwinds and wind gusts.

On the mainland, torrential rains and flooding may remain complicated over the next few days.

Between Sunday and Tuesday, heavy downpours could pound the central Vietnamese provinces from Quang Binh to Binh Dinh, with rainfall likely topping 400mm.

Rainfall could exceed 800mm in several parts of Thua Thien-Hue Province, Da Nang City, and Quang Nam Province.

Downpours and thunderstorms may also hit the Central Highlands region and southern Vietnam mostly on Sunday afternoon and at night.

From Tuesday to Wednesday, rain will possibly expand into the northern region, the center said.

A report released by the national steering committee for natural disaster prevention and control showed that heavy rains in central Vietnamese provinces in recent days have left two people dead and inundated more than 1,500 houses, with some 1,430 in Da Nang.

The foul weather also flooded numerous roads in Quang Binh, Thua Thien-Hue, and Da Nang.

Over the past two days, authorities in Da Nang dispatched over 4,800 officials and soldiers to vulnerable areas and evacuated more than 6,800 residents from flood-hit areas to safer places, as well as allowed all students citywide to stay home.

Authorities in neighboring Thua Thien-Hue also evacuated 421 people from flooding- and landslide-prone locations.
