Risk of flash floods, landslides and flooding due to heavy rain after storm
The circulation of storm No. 3 is still causing rain in many places in the Northern region, bringing with it a series of post-storm natural disaster risks. Mr. Hoang Van Dai, Deputy Director of the National Center for Hydro-Meteorological Forecasting, General Department of Hydro-Meteorology, said that in the next 24-48 hours, the northern region is forecast to continue to have heavy rain. In particular, the Northwest region may have rainfall of 100-200mm; the Northwest region has rainfall of 60-70mm.
With such post-storm rain developments, Mr. Hoang Van Dai warned of a high risk of flooding on rivers and streams, flash floods and landslides in some localities. Of particular note, small rivers in Quang Ninh, Lang Son, Cao Bang, Hoa Binh could see flooding from alert level 2 to alert level 3. Floods on rivers such as Ngoi Thia (Yen Bai), Song Boi (Hoa Binh), Hoang Long (Ninh Binh) could rise above alert level 3; the downstream of Luc Nam River would rise to alert level 2.
There is a high risk of flooding in urban areas, cities and provinces in the Northern Delta region due to heavy rain, especially in the provinces of Quang Ninh, Hai Phong, Lang Son, Thai Nguyen, Cao Bang, Ha Giang, Yen Bai, Bac Kan, Nam Dinh, Thai Binh, Ha Nam, and Hanoi.

"With the risk of many types of natural disasters like this, we recommend that people regularly and closely monitor warning bulletins about rain and other dangerous weather conditions. People need to observe cracks in walls and houses around their living areas. People living near rivers and streams should limit their travel to those areas. If people are in areas where flash floods and landslides are warned, they should limit their travel unless necessary. If traveling on a national highway, they should observe the surrounding areas for potential landslides; if passing through overflow tunnels or streams flowing down steep slopes, they should pay special attention," Mr. Dai advised.
