Heavy rainfall since September 22 has caused the Lam Tra River in Hung Dao Commune to swell rapidly. By September 23, the Hung Dao dyke was at risk of overflowing. The river water had risen almost level with the top of the dyke, while the rain continued unabated.
In response, Hung Nguyen District authorities implemented emergency measures from the morning of September 23. Three excavators were mobilized to build an emergency embankment, preventing overflow; personnel were deployed to handle any incidents, and residents were barred from crossing.
A breach in this dyke would affect and flood hamlets 5, 6, and 7 of Hung Dao Commune. The residents have been notified and advised to elevate their belongings to minimize flood damage.
Local authorities have mobilized forces to survey and identify households in need of support to elevate their belongings. In the event of a dyke breach or collapse, they will focus on assisting and evacuating residents to safety.
On the afternoon of September 23, Vice Chairman of the People’s Committee of Nghe An Province, Nguyen Van De, and representatives of relevant units inspected the site and directed the remediation work to ensure the safety of people and property. The Hung Dao dyke is approximately 15km long, starting at Nam Giang Commune and ending at Kim Lien Commune in Nam Dan District.
Regarding the situation at reservoirs, the Water Resources Exploitation and Protection Division reported that Nghe An Province has 1,061 large and small reservoirs. In this round of rain, 51 reservoirs were filled, with 13 of them reaching warning levels (water levels exceeding the spillway).
To ensure reservoir safety, local authorities and irrigation units deployed forces to operate and monitor the reservoirs 24 hours a day. For large reservoirs, they regularly monitored water levels, checked rain gauges, and automated spillway gate opening systems to ensure safety.
According to the National Center for Hydro-Meteorological Forecasting, there will be moderate to heavy rain and thunderstorms in the area from southern Nghe An to Quang Binh in the afternoon and evening of September 23, with average rainfall ranging from 20-50mm and over 100mm in some places.
Additionally, scattered showers and thunderstorms are expected in Thanh Hoa, northern Nghe An, and from Quang Tri to Quang Nam in the afternoon and evening of September 23, with average rainfall of 10-30mm and over 50mm in some places. These storms may be accompanied by tornadoes, lightning, and strong gusts.
The heavy rain in the Central region is expected to subside from September 24. However, the intense and localized rainfall may cause flooding in low-lying areas and flash floods in small rivers and streams, as well as landslides on slopes.
