The water level in the upper Red River has peaked and is falling.

Speaking to the press today, September 11, about the weather developments taking place in the North, Mr. Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting (NCHMF), said that the latest data from last night to this morning, in most mountainous and midland areas of the North, rainfall has tended to decrease compared to the previous 2 days.

“From dawn until now, the rain has mainly been concentrated in the delta region and the Northeast region, moving into the North Central region. We forecast that today and until the end of tomorrow, the rain will continue in the middle of the delta region and the North Central region. It is possible that after tomorrow, the rain will show signs of decreasing,” Mr. Khiem predicted.

The danger will last for the next 1-2 days.

Regarding the flood situation on the Red River and Thai Binh River, Mr. Khiem informed that from last night until now, the flood on the Red River has been increasing. At 10:00 this morning, the water level of the Red River in Hanoi rose to 11.02 m, 3.48 m lower than the warning level. Compared to past data, the water level of the Red River in Hanoi rose above 11 m in 2004, that is, 20 years ago. At that time, the highest level was 11.04 m.

Mr. Mai Van Khiem spoke to the press today, September 11.

In the coming hours, according to Mr. Khiem, because the water level in the upstream is still changing slowly, there is a possibility that the water level on the Red River in Hanoi will tend to increase but at a slow rate. "We assess that with this water level, the risks related to the downstream are high, especially in low-lying areas, riverside areas; most rivers will rise to alert level 3," Mr. Khiem assessed.

Regarding this issue, Mr. Vo Van Hoa, Director of the Northern Delta and Midlands Hydrometeorological Station, stated that there are still some provinces at high risk such as Thai Nguyen and Bac Giang . Regarding Thai Nguyen, Mr. Hoa said, the special thing is that this province has never experienced flooding in history, according to recorded data.

People in the suburbs of Hanoi hurriedly evacuated their property and pets to safety.

In Bac Giang, according to Mr. Hoa, most communes bordering the Thuong and Cau rivers are still showing an upward trend in the next 6 hours and are currently at alert level 3. The danger may still last for the next 1-2 days.

“The characteristics of this year's floods in Bac Giang are similar to those in 2008 and 1986, when prolonged flooding occurred and caused a lot of economic and social damage,” Mr. Hoa assessed.

In the Hanoi area, flooding has occurred along major rivers such as the Red River, Da River, Duong River, and Day River. It is forecasted that in the next 6 hours, the water level in these major rivers will continue to rise. However, during this time, it will reach 1.3 m, which is about 20 cm below alert level 3, and then level off.

Mr. Vo Van Hoa shared with the press

Assessing the risk, Mr. Vo Van Hoa said that the inner city areas such as Tay Ho, Hoan Kiem, Long Bien are also flooded, and it is likely that in the next 6 hours, when the water level of the Red River continues to rise, this risk will still exist. In addition, a series of suburban districts such as Ung Hoa, Chuong My, Phuc Tho, Son Tay, Ba Vi, Gia Lam, Dong Anh and Ha Dong district are still affected by small rivers, the inner-provincial rivers are rising and will continue to cause localized flooding.

“The biggest risk we see now is the risk of prolonged flooding in districts like Chuong My. The reason is that the water level in the main rivers is very high, the drainage is affected, so prolonged flooding may occur. We are providing flood warning bulletins in Hanoi, we will also closely monitor to regularly issue flood warnings,” said Mr. Hoa.

Further assessing this flood, Mr. Mai Van Khiem acknowledged that it can be said that this is a rare flood and according to statistical data up to now, most of the measuring points on the Red River, Thai Binh River, Thao River, Lo River... are above alert level 3. In particular, the measuring point on the Thao River in Lao Cai and Yen Bai has exceeded historical values.

High water level, slow drainage

Updating the “positive” information, Mr. Vu Duc Long, Director of the Department of Hydrometeorological Forecasting Management, pointed out that currently, some rivers upstream of the Red River such as the Thao River, the water level in Lao Cai and Yen Bai has peaked and is decreasing.

With Hoa Binh Lake closing one more sluice gate this morning (that is, closing the last sluice gate of this lake) and Tuyen Quang Lake continuing to close two more sluice gates (this morning and afternoon - PV), the water source downstream has decreased.

Mr. Vo Van Long updated information on water situation on rivers.

However, Mr. Long said, there are still disadvantages in that the water level on the rivers is still very high and receding very slowly. Especially in the downstream and delta areas, most of the measuring points are at alert level 3 or higher; some rivers have experienced historic floods.

“Now the water above continues to fall, the water below is high so the drainage capacity will be slow. Thus, the flooding period will last, at least for the next 2-3 days,” Mr. Long worried and noted that the key time in the downstream area could be today and tomorrow. The downstream provinces directly affected include: Hung Yen, Ha Nam, Nam Dinh.

There is no flooding in Hanoi's inner city.

Citing misleading information on social media that the water level on the Red River is rising and has flooded the inner city, Mr. Long affirmed that this is not true.

“I would like to explain further that for the flood on the Red River, even though it is rising now, we recently updated it to 11.1 m, 0.6 m above alert level 2, flooding will only occur in areas outside the dike such as Phuc Tan, Phuc Xa, Bach Dang street, and cannot enter the inner city,” Mr. Long emphasized.
