Warning of the risk of flash floods on small rivers and streams, landslides on steep slopes in the above provinces, especially in the communes and wards: Hiep Duc, Kham Duc, Phu Thuan, Phuoc Hiep, Phuoc Thanh, Que Phuoc, Tra Doc, Tra Leng, Viet An ( Da Nang city); Dak Ha, Dak Mar, Dak Plo, Dak Pxi, Dak To, Dak Ui, ​​Kon Dao, Ngok Bay, Ngok Reo, Ngok Tu, Ro Koi, Sa Binh, Son Ha, Ya Ly (Quang Ngai province). The level of risk of natural disasters 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, provinces and cities need to use structural and non-structural measures.

Regarding engineering measures, it is necessary 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, it is necessary to create a map 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 and landslides.

From 4:00 p.m. to 5:00 p.m. on September 16, the areas of Da Nang and Quang Ngai provinces and cities will have moderate rain, with some places experiencing heavy rain such as: Thang Phuoc (Da Nang city) 54.6mm; La Dee (Da Nang city) 31mm; Dak Hring (Quang Ngai) 67mm; Van Lem (Quang Ngai) 29.4mm...

Soil moisture models show that some areas in the above provinces are close to saturation (over 85%) or have reached saturation.
