Severe weather continues to impact Vietnam, characterized by heavy rainfall, rising river levels, and significant urban disruption. In Northern and North Central regions, flooding has become widespread. In Ninh Binh, the Hoang Long and Day rivers reached critical levels, with the Hoang Long exceeding Alarm Level 3. In Nghe An, floodwaters damaged the Khe Da Han bridge, and in Thanh Hoa, the Buoi River flooded homes and fields. By September 21, the scale of destruction grew, with nearly 20,000 homes inundated and at least three deaths reported. In August 2026, a tropical depression and Typhoon Narra triggered extensive landslides and flooding, particularly in Lang Son and Quang Ninh. These storms caused significant agricultural losses and fatalities, including at least one death in Dak Lak due to a falling tree. ~~In late August, heavy rains in Hanoi caused urban flooding, while Central Vietnam experienced intense heatwaves.~~ By mid-September, record-breaking rainfall was recorded in Vinh, Nghe An, breaking a 41-year record. Severe flooding in Ninh Binh and Nghe An led to over 2,000 homes being submerged, and landslides in Phu Tho caused at least three deaths. In late September, flooding and landslides expanded to Dong Nai, where the Buong and Thao rivers inundated residential areas and cut off roads. In Lam Dong, over 1,890 houses were flooded, prompting the evacuation of nearly 1,000 people.
