Following days of heavy rain causing severe flooding in the provinces of Cao Bang, Thai Nguyen, and Lang Son, on the afternoon of October 8th, Mr. Le Ngoc Quyen, Deputy Director of the Northern Meteorological and Hydrological Station (Department of Meteorology and Hydrology, Ministry of Agriculture and Environment ), stated that the weather in the North is gradually improving, but flood levels on many rivers remain high, and in some places, they have even exceeded historical levels.
"The main cause of the recent floods is the remnants of Typhoon No. 11, which weakened into a low-pressure area after making landfall in Guangxi Province (China), combined with strong southeasterly winds and southwesterly winds from the Bay of Bengal, creating a convergence zone of winds over the Northern Vietnam region," Mr. Le Ngoc Quyen informed.

Accordingly, in just 36 hours, from the morning of October 6th to the evening of October 7th, rainfall in Thai Nguyen reached 200-400mm, with some areas nearing 600mm; Cao Bang and Lang Son generally received 100-200mm, with some points exceeding 300mm. This amount of rainfall exceeded the average for October each year, causing severe flooding in many areas due to the steep terrain and narrow river systems with slow drainage.
According to the Northern Vietnam Meteorological and Hydrological Station, from today, October 8th, the weather in the Northern region has gradually improved, with sunshine, and showers and thunderstorms are only localized, with no possibility of widespread heavy rain.

However, river levels remain high. Over the past 24 hours, many hydrological stations such as Gia Bay (Cau River), Huu Lung (Trung River), and Cau Son (Thuong River) have exceeded alarm level 3 by 2-5 meters and are all higher than historical flood levels. Currently, floodwaters on most rivers are receding, but the Trung River (Lang Son) and Cau River (Bac Ninh) are still rising slowly, predicted to peak tonight, October 8th, or tomorrow morning, October 9th, exceeding alarm level III by about 1-2 meters.

"Flooding in Thai Nguyen could last for another 3-4 days, and even longer in low-lying areas of Dong Hy, Phu Binh, and Dai Tu. In Bac Ninh and Lang Son, the flooding will last for 2-3 days, while in Cao Bang it will be about 1-2 days," the Deputy Director of the Northern Meteorological and Hydrological Station informed.
