Heavy rain in the North; flooding in Thai Nguyen, Bac Ninh and Hanoi may last 1-2 days

On the afternoon of October 12, Director of the National Center for Hydro-Meteorological Forecasting Mai Van Khiem said that due to the influence of weak cold air combined with the East wind from the subtropical high pressure circulation encroaching on the West, during the period from October 13 to 15, the Northern region, especially the Northeast, is likely to experience rain, moderate rain, and cloudy weather.

Warning, flooding in Thai Nguyen, Bac Ninh provinces and Hanoi city is still continuing in riverside communes and wards, low-lying areas and may last for the next 1-2 days.

Mr. Mai Van Khien noted that the cumulative rainfall forecast for 24 hours is generally below 50mm, so the possibility of flooding on river systems is very low. However, during this time, there may still be localized showers and thunderstorms, with heavy rainfall of 30-50mm/hour, which can cause flooding, flash floods and landslides in some mountainous areas. The National Center for Hydro-Meteorological Forecasting will continuously monitor and update short-term and very short-term forecasts (1-3 hours in advance) to promptly warn people and local authorities if there are unusual developments.

Urgent flood warning on Thuong River

According to the National Center for Hydro-Meteorological Forecasting, from 4:30 p.m. on October 12 to 3:30 a.m. on October 13, flood on Thuong River at Phu Lang Thuong station will continue to decrease and be below alert level 3; flood on Cau River at Dap Cau station will decrease to alert level 2.

In the next 12-24 hours, flood on Cau River at Dap Cau station will continue to decrease and be above alert level 1; flood on Thuong River at Phu Lang Thuong station will continue to decrease and be above alert level 2.

Warning, flooding in Thai Nguyen, Bac Ninh provinces and Hanoi city is still continuing in riverside communes and wards, low-lying areas may last for 1-2 days; risk of riverbank erosion, river dykes and landslides on slopes in the above areas. (Real-time warning information on areas at risk of flash floods and landslides is provided online on the website of the Department of Hydrometeorology at: https://luquetsatlo.nchmf.gov.vn and in a separate bulletin warning of flash floods and landslides)

Flood disaster risk level 3.

River floods inundate low-lying areas along the river, affecting activities such as waterway transport, aquaculture, agricultural production, people's lives and socio- economic activities. Affected localities take precautions against environmental pollution and epidemics in areas where floodwaters have receded.

"The forecast and warning information is calculated based on the expected discharge levels of upstream reservoirs. The hydrometeorological agency will update the bulletins when there are changes in the discharge flow of the reservoirs," noted Hoang Van Dai, Deputy Director of the National Center for Hydrometeorological Forecasting.
