Heavy rainfall has triggered various landslides and flooding incidents across multiple Vietnamese provinces.

In Lam Dong Province, flash floods and landslides occurred along National Highway 55 in La Da Commune. The weather caused approximately 200 cubic meters of earth to block the road and damaged residential structures in Da Mi 1 and Da Mi 2 villages. Local authorities cleared the debris to restore traffic between Ham Thuan Bac and Bao Loc.

In Da Nang, a landslide on the DH7 NTM road blocked vehicle access between Tra Linh commune and Konpin village. Approximately 40 cubic meters of earth and rock fell from a slope, creating a 15-meter long blockage. Local military authorities have deployed warning signs and instructed residents to use alternative routes.

In Dong Nai, severe soil erosion in the Doc Khi area of Phuoc Son commune has made a red dirt road unstable. The route, situated between high earthen cliffs, is essential for hundreds of local rubber tappers and farmers who face risks navigating the narrow, rutted terrain.

In Thanh Hoa province, heavy rainfall between November 8 and 9 has caused significant infrastructure damage. Most notably, the Bai Sim bridge abutment on the Nghi Son - Bai Tranh highway collapsed, severing a vital route that connects the Nghi Son Economic Zone and port to Highway 1 and the North-South Expressway. This disruption affects the transport of goods to western Thanh Hoa and neighboring provinces. Additionally, landslides along the Ho Chi Minh Highway and rising water levels in the Yen River and Yen My Lake have caused localized flooding and forced household evacuations in districts such as Nong Cong and Thanh Ky. The Vietnam Road Administration has deployed personnel to manage traffic and implement detours, though officials warn that continued heavy rain through November 11 may complicate recovery efforts.
