The combined effect of the South China Sea low pressure zone and the tail of the cold front caused a short-term concentrated rainstorm.

[7] As of 14 November, according to the Government of Vietnam, the following figures were reported: 622 fatalities, 70 individuals missing, and a need for relief assistance for over 1 million people.

[10] According to provisional data from the Vietnamese CCFSC among the fatalities, 324 resided in Thừa Thiên Huế province, while on 9 November it was reported that 15,000 people had to evacuate.

[11][7] The damage to transportation routes due to the floods limited access to medical care, with 510 health clinics already being reported battered.

[13][14][15] According to reports from local media a rash of illnesses, including dengue fever, diarrhoea, flu, eye infections and respiratory problems, had spread to five of the eight coastal districts devastated by the floods.

[17] The local population faced significant health risks, including psychological conditions, stemming from anxiety and the abrupt disturbance of their well-being, which may persist years beyond the receding floodwaters.

[18][17] The shortage of findings about the effects of the floods on mental health reveals that conditions like anxiety and post-traumatic stress disorder (PTSD) remained neglected.

[10] The flooding experience proved most distressing for the lowland residents, particularly for those who had nowhere to seek refuge when the water levels surged, reaching the rooftops of their homes.

According to a report published by the UN Office for the Coordination of Humanitarian Affairs, sections of National Highway One, vital for connecting Hanoi and Ho Chi Minh City, remained inaccessible for days after the flooding, as did extensive stretches of the north-south railway.

[11] Despite significant material damage, including reports of 94,000 shattered classrooms, education remained remarkably resilient, as the majority of families persisted in enrolling their children in school, despite encountering economic challenges.

[25] Consequently, the 1999 floods resulted in widespread food shortages for over 1 million people, particularly those living in isolated, rural areas dependent on rice as a staple.

This resulted in many families experiencing hunger when floodwaters destroyed their crops because food assistance did not arrive in Hong Ha until one week after the floods.

[4] Vegetable and bean seeds were provided by the Hue University of Agriculture and Forestry and many lowland households borrowed rice from neighbours with the intention of repaying after the next harvest.

7/1999/CT-TT on flood preparedness, established in May 1999, all branches and levels deployed active plans against natural calamity including the identification of evacuation sites.

[34] Residents were advised to evacuate on the first day of the flood by commune CCFSC officials who issued warnings by bells, loudspeakers, and radio.

Rescue activities and commodities supply were supported by the transportation sector, which repaired the roads and rail infrastructure from the North to the South, which had been blocked for many days.

[35] The Red Cross-National Society in Vietnam (VNRC), assisted by the country, provided support and manpower in flood emergency relief.

Red Cross volunteers also helped to collect the dead and livestock to prevent the outbreak of post-flood diseases, as well as transported instant noodles and communications equipment to the affected communities.

[36] The Central Committee for Flood and Storm Control (CCFSC) in coordination with relevant Ministries, was requested to immediately provide emergency support on the 3 November.

Less than four weeks following the dissipation of the November rainstorm, central Vietnam again experienced heavy rainfall with extensive flooding, just as relief efforts were underway.

From 1 to 6 December, rain in mountainous regions caused flash floods and blocked main travel routes, with areas of the National Highway No.1 up to 1.7 metres underwater and part of the north-south railway obstructed.

[39] The need for emergency relief was imperative, particularly as seeds for rice and vegetables that had been distributed in earlier aid efforts were destroyed by further flooding and therefore in significantly short supply.

The Catholic Relief Services alongside the People's Committee of Thừa Thiên Huế signed a Memorandum of Understanding in which they pledged to build approximately 120 houses in the Quảng Trị province.

[44] Additionally, the primary care system within areas most frequently affected by flooding in Vietnam does not have the capacity to respond to and treat flood-related issues.
