From now until November 5, the flood on rivers in Ha Tinh, Quang Tri, and Quang Ngai is likely to rise again. During this flood, the peak water level on Ngan Sau and Ngan Pho rivers (Ha Tinh), Gianh River, Kien Giang River, and Thach Han River (Quang Tri) will reach alert level 2 - alert level 3, with some rivers above alert level 3.

Warning of flood risk in low-lying areas along rivers, urban areas, and densely populated areas in provinces/cities from Ha Tinh to Da Nang. High risk of flash floods on rivers and streams and landslides on slopes in provinces/cities from Ha Tinh to Da Nang. Warning of level 3 flood risk.

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

Floods on rivers and inundation in low-lying areas affect activities such as water transport, aquaculture, agricultural production, people's lives and socio-economic activities.

Risk of flooding in low-lying coastal areas in the Southeast region

According to information from the National Center for Hydro-Meteorological Forecasting, from the evening of November 3 to November 4, the coastal areas of provinces/cities from Ho Chi Minh City to Ca Mau at Vung Tau station will have a high water level of 4 - 4.1m, with peak tides occurring from 11am - 1am and from 1pm - 4pm. Areas at risk of flooding due to high tides are low-lying areas and areas outside the dike.
