Heavy rainfall and a strong cold air mass have triggered significant weather warnings and damage across central and northern Vietnam. Between November 8 and 11, extreme precipitation, with some areas recording over 700 mm, has caused widespread flooding, landslides, and infrastructure damage. In Thanh Hoa, heavy rains caused the Yen River to exceed alarm level 3 and led to the collapse of the Bai Sim bridge on the Nghi Son-Bai Tranh route. Flooding has impacted local cemeteries and over 1,000 households in Nông Cống commune, forcing some families to evacuate. The severe weather has also resulted in the closure of schools for nearly 12,000 students. In Quang Tri, rising waters forced the removal of a floating bridge, requiring students to travel by boat. Additionally, hundreds of trucks were stranded on National Highway 15D due to flooding near the La Lay international border gate. Authorities also rescued 10 people trapped in a forest due to rising waters. In Hue, rising levels in the Truoi River have flooded residential areas. To manage inflows, officials have increased water discharge from the Huong Dien and Binh Dien hydroelectric reservoirs, issuing warnings for residents near the Bo River. Local schools in certain wards have also suspended classes. In Da Nang, torrential rain and strong winds have uprooted trees, damaged vehicles, and blocked major city streets. Authorities have issued landslide warnings in 31 communes, advising tourists to avoid mountainous regions like the Son Tra Peninsula. In Khanh Hoa, floodwaters submerged construction machinery at the Thac Ngua bridge site. In Quang Ngai, officials evacuated dozens of households in the Dak Re mountain area due to landslide risks. In the north, the cold air mass has brought lower temperatures, with some mountainous regions dropping below 10 degrees Celsius.
