The National Civil Defence Steering Committee called on ministries and local authorities to closely track rainfall and flooding, with particular attention to the Thanh Hoa-Hue region.
River levels from Ha Tinh to Hue, particularly in the Thach Han basin in Quang Tri, should be closely monitored, while warnings should be issued to local communities over rapidly rising floods, deep inundation and the risk of isolation.
Access to flooded crossings, bridges and areas with strong currents should be restricted. Concerned agencies were also told to review evacuation plans for riverside, low-lying and other areas at risk of severe flooding, flash floods and landslides, and move residents out of high-risk locations when necessary.
Ministries and localities were instructed to maintain round-the-clock emergency operations to ensure timely reporting and coordination.
As of 5 pm on Saturday, the tropical depression and subsequent flooding had damaged nine homes, including five in Quang Tri and four in Hue, according to the Department of Dike Management and Disaster Prevention.
Another 409 homes were flooded in Quang Tri, while flooding blocked traffic at five locations on roads in Quang Tri and Hue.
Forty-eight bridges, crossings and local roads were submerged by 0.2-0.8 metres of water, with some areas under more than one metre, leaving several communities temporarily isolated.
Floodwaters were receding in much of Hue by Saturday afternoon, although flooding persisted in Phong Dien and Phong Dinh.
In Quang Tri, heavy rain damaged roofs at five homes in Sen Ngu Commune and breached a roughly 800-square-metre fish pond in Tan Lap Commune, causing estimated losses of VND 30 million. Other fish ponds were also flooded.
About 16.5 hectares of rice fields across the province were flooded or damaged.
Rising river levels also swept three large barges into My Chanh railway bridge, where they became lodged. Local authorities and emergency forces were working on plans to remove them and minimise risks to rail traffic.
