Warning of the risk of flash floods on small rivers and streams, landslides on steep slopes in many communes/wards in the above provinces such as: La Lay, Ta Rut; A Doi, Ba Long, Dakrong, Huong Phung, Kim Ngan, Truong Son (Quang Tri province); Duc Binh, Ea Pal, Son Hoa; Cu Pui, Dlie Ya, Ea Kar, Ea Kly, Ea O, Krong Nang, M'Drak, Suoi Trai, Tam Giang, Vu Bon ( Dak Lak province); Anh Dung, Bac Ai, Bac Ai Dong, Cong Hai, Dien Tho, Lam Son, My Son, Ninh Son, Phuoc Huu, Thuan Bac, Van Hung (Khanh Hoa province).

Warning level of natural disaster risk due to flash floods, landslides, land subsidence due to heavy rain or level 1 flow.

Flash floods and landslides can have very negative impacts on the environment, threaten people's lives; cause local traffic congestion, affect the movement of vehicles; destroy civil and economic works, causing damage to production and socio-economic activities.

The hydrometeorological agency recommends that local authorities pay attention to reviewing bottlenecks and vulnerable locations in the area to have prevention and response measures.

To prevent flash floods and landslides, disaster prevention experts say that provinces and cities need to use engineering and non-engineering solutions.

Regarding engineering measures, provinces and cities need to plant and protect upstream protective forests, especially in areas that often cause flash floods, to protect the ecological environment, protect the vegetation cover, increase the water retention capacity of the basin, and limit the ability to concentrate flood flows. At the same time, build reservoirs to regulate floods in areas where flash floods often occur, clear flood drainage routes, build dikes, flash flood walls, divide flood flows, build additional spillways in reservoirs, etc.

For non-structural measures, localities need to create maps of flash flood risk zones (high risk; medium risk and areas with low risk of flash floods). This map is one of the important bases for localities to propose measures to prevent flash floods; land use planning to limit development in areas with high risk of flash floods. For residential areas that have developed without planning in the past, localities need to re-plan and resettle, moving people out of areas with high risk of flash floods, landslides...

From 3:00 p.m. to 5:00 p.m. on September 30, the provinces of Quang Tri, Dak Lak and Khanh Hoa had moderate to heavy rain such as: Ta Rut (Quang Tri) 64.8mm; Suoi Vuc Dam (Dak Lak) 52.8mm; Da Nhim Hydropower Plant (Khanh Hoa) 86.6mm...
