A particularly dangerous form of rain appears in the North.

According to Mr. Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting, from early morning and the morning of October 7, a very heavy rain appeared in the northern provinces including Tuyen Quang, Cao Bang, Thai Nguyen, Phu Tho, Hanoi , Lang Son, Bac Ninh, in which Thai Nguyen and Hanoi had especially heavy rain.

Rainfall from 7pm on October 6 to 9am on October 7 in some places in Thai Nguyen was over 450mm, such as Hoa Thuong station 526mm, Cay Thi station 462mm.

Bac Ninh , Hanoi, Lang Son, Quang Ninh recorded rain over 200mm such as Bo Ha station (Bac Ninh) 348mm, Me Tri station (Hanoi) 261.6mm, Soc Son station (Hanoi) 242.4mm, Tan Tri 1 station (Lang Son) 224.4mm, Chuc Bai Son station (Quang Ninh) 216mm.

The cause of this rain, according to Mr. Khiem, is the influence of the weakened low-pressure circulation from storm No. 11, combined with the southeast wind zone of the subtropical high pressure tongue encroaching strongly from the east, creating a convergence zone of meridional winds in the Northeast region, running along the above provinces.

This is also the form that caused the exceptionally heavy rain on September 30 in the North, with the focus on Hanoi, leading to widespread flooding in the capital and many northern provinces. This form of rain is characterized by very long rain duration, high intensity rain accompanied by strong thunderstorms.

The areas that suffered the heaviest rain in these two periods in the capital were concentrated in the inner city and the north of Hanoi, and at the same time, there was an especially heavy rainfall intensity within one hour.

On September 30, the rain within one hour at Dinh Cong station was 101.4mm. In this morning's rain, the heaviest rain in one hour recorded at Me Tri was up to 108.2mm.

According to Mr. Mai Van Khiem, the current meridional wind convergence is showing signs of weakening, so in the afternoon of October 7, the North will still have moderate to heavy rain with rainfall in Tuyen Quang, Thai Nguyen, and Hanoi of about 30-60mm, some places over 100m, other places will have rain from 20-30mm. From the evening of October 7, the rain will decrease, but by the early morning of October 8, the Northeast region may have rain and moderate rain again.

Since the end of August, Hanoi has suffered three particularly heavy rains, causing widespread flooding.

Due to the impact of heavy rain from today (October 7) to October 10, floods on rivers in the Northern region and Thanh Hoa continue to rise.

During this flood, the flood peak on rivers in Cao Bang, Lang Son, Quang Ninh, Luc Nam River (Bac Ninh), Thai Binh River (Hai Phong) reached level BĐ2-BĐ3 and above BĐ3.

Flood peaks on Thao River (Lao Cai), Lo River (Tuyen Quang), Hoang Long River (Ninh Binh), and the upper reaches of Ma River (Thanh Hoa) are at level 1-2, with some rivers above level 2. Flood peaks reaching Hoa Binh Lake and the lower reaches of the Red River at Hanoi station are likely to be above level 1.

The meteorological agency continues to warn of widespread flooding in Thai Nguyen, Bac Ninh, Lang Son, Cao Bang and the risk of flooding in low-lying riverside areas and urban areas in the Northern region and Thanh Hoa.

In addition, there is a very high risk of riverbank and dike landslides, flash floods on rivers and streams, and landslides on steep slopes in the mountainous areas of the North and Thanh Hoa.
