National authorities reported severe destruction across Gia Lai, Dak Lak, and Khanh Hoa Provinces, where 114 communes and wards remain heavily flooded.

Massive inundation, extensive damage

A rapid report from the Vietnam Disaster and Dyke Management Authority said 168 homes were destroyed while nearly 68,000 others were underwater.

Flooding also ruined more than 13,000 hectares of rice, vegetables, and other short-term crops, along with 2,000 hectares of perennial plants.

Over 30,000 livestock and poultry were killed or swept away.

Roads suffered extensive disruption.

Thirty locations on national highways remained blocked, including two sections on National Highway 1, 14 points on the Truong Son Dong road, one point on National Highway 14, and two points on National Highway 20 where landslides cut off both Prenn Pass and Mimosa Pass in Lam Dong Province.

Another 142 provincial and local roads were submerged or collapsed.

Rail transport was halted on six passenger trains on Thursday, while Tuy Hoa Airport in Dak Lak suspended operations from 10:00 am until midnight. 

More than one million households lost electricity during the flooding, and power has been restored to about 615,000 of them.

Preliminary estimates place economic losses at more than VND3 trillion (US$114 million).

Rivers rising unevenly as heavy rain persists

The national weather agency reported continued heavy rain from Quang Ngai to Dak Lak and northern Khanh Hoa from Thursday night through early Friday, with rainfall exceeding 100mm at several stations such as Song Hinh 4 (127mm) and Dai Lanh (103mm).

Water levels on the rivers from Hue City to Khanh Hoa are receding, except the Krong Ana River in Dak Lak, which continues to rise above alarm level 3.

Water levels on the Ba River at Cuong Son Station are forecast to fall below alarm level 1, while Phu Lam will remain above alarm level 2 on Friday.

Widespread flooding is expected to persist from Gia Lai to Khanh Hoa until rainfall weakens.

More heavy rain expected through Sunday

Moderate to heavy rain is anticipated across eastern parts of Da Nang to Dak Lak and southern Khanh Hoa on Friday, with 40-80mm expected and local amounts above 150mm.

From Saturday through Sunday, Da Nang, Quang Ngai, Gia Lai, and Dak Lak may continue to receive 30-60mm of rain, with some areas exceeding 100mm.

Rainfall is projected to decrease sharply from Monday.

High disaster risk continues in Dak Lak, Khanh Hoa

Authorities warn that landslide, flash flood, and ground subsidence risks remain extremely high in parts of Dak Lak and Khanh Hoa, where soil moisture has reached saturation above 85 percent.

High risk areas include dozens of communes such as Cu M ta, Cu Pui, Ea Trang, Hoa Xuan, Tuy An Bac, Tuy An Nam, Van Hoa, and Yang Mao in Dak Lak and Cam Lam, Dien Dien, Dien Tho, Ninh Hoa, and Van Ninh in Khanh Hoa, among others.

Flooding cripples major routes, including National Highway 1

Traffic chaos continued on Friday morning along National Highway 1 from Song Cau to Tuy An in Dak Lak, where floodwaters submerged long stretches.

Hundreds of trucks and tractor trailers were stranded for hours in lines several kilometers long.

Deep flooding near Xuan Tho Commune created a major bottleneck, forcing many vehicles to wait for water levels to fall.

Traffic police worked through the night to guide essential vehicles such as military rescue teams and relief convoys heading to heavily flooded areas in Tuy Hoa, Tuy An, and Nha Trang.

Authorities urged drivers not to enter submerged residential roads because of the high risk of landslides and engine failure.

In downtown Nha Trang, which is a beach destination in Khanh Hoa, the Ngoc Hoi intersection near Tay Nha Trang Ward remained barricaded after two days of severe flooding.

Rescue boats used for evacuations were parked along the ramp of the overpass, preventing regular vehicles from using the route.
