Floods on rivers from Quang Tri to Quang Ngai tend to rise again
Regarding the hydrological situation, currently, the flood on the Huong River (Hue city) is fluctuating above alert level 2. Floods on rivers in Ha Tinh and Tra Khuc River (Quang Ngai) are rising. Meanwhile, on rivers in Quang Tri, Hue city and Da Nang city, there were slight fluctuations.
At 8:00 a.m. on November 1, 2025, the water level on the Huong River at Kim Long station reached 2.45 m (0.45 m above alert level 2); on the Bo River at Phu Oc station was 3.28 m (0.28 m above alert level 2); on the Tra Khuc River at Tra Khuc station was 4.69 m (0.31 m below alert level 2).

In the next 24 hours, floods on rivers in Hue city will increase and reach below alert level 3, while Tra Khuc river will continue to rise and is likely to reach alert level 3.
From now until November 5, there is a possibility of a new flood on rivers from Nghe An to Ha Tinh, while floods on rivers from Quang Tri to Quang Ngai tend to rise again.

The flooding situation in Hue city is decreasing, but we still need to be vigilant against the risk of flooding in low-lying areas along rivers, residential areas and urban areas in provinces from Nghe An to Quang Ngai. There is a high risk of flash floods on rivers and streams and landslides in mountainous areas of these provinces.
Real-time warning information of flash flood and landslide risks is updated at https://luquetsatlo.nchmf.gov.vn and in separate warning bulletins.
The risk level of natural disasters due to floods is level 2. Floods on rivers and flooding in low-lying areas can affect waterway traffic, aquaculture, agricultural production, people's lives and socio-economic activities.
Forecast and warning information is calculated based on the assumption of regulating the operation of upstream reservoirs. The Hydrometeorological Agency will continue to update bulletins when there are changes in the discharge flow of reservoirs.
