Flooding in Northern Vietnam Escalates Amid Heavy Rains

Core Event – Floods and Landslides Since Mid-September
Heavy rains that began on September 14 have produced widespread flooding and landslides across northern Vietnam. Government data indicate that some locations received up to 653 mm of rain. The deluge inundated more than 16,000 houses, damaged over 22,000 ha of rice and other crops, and triggered 11 landslides affecting 30 road sites. The Hanoi-Ho Chi Minh City railway was submerged to about one metre deep, prompting the suspension of several north-south train services on September 17 and September 18.
Background & Context – Seasonal Risks and Climate Factors
Vietnam’s long coastline makes it prone to storms from the South China Sea. Government officials note that climate change and deforestation have heightened the country’s vulnerability to severe flooding. The 2026 season is projected to see up to five additional storms, with one or two potentially reaching the mainland.
Impact – Human Toll, Property Damage, and Agricultural Losses
The flooding has claimed three lives. In the coastal province of Thanh Hoa, more than 29,000 officials and soldiers were mobilised for emergency assistance. National and provincial roads remain disrupted, and traffic congestion has been reported in Hanoi, where some schools shifted to online classes or gave students a day off on September 17. Government estimates place total economic losses at roughly 2.2 trillion dong (about S$107.91 million), a figure that is 84.9 % lower than the losses recorded for the same period in 2025, when severe typhoons struck the country.
Official Statements & Responses – Government Actions and Forecasts
A statement on the government’s website warned that heavy rain will continue from Thanh Hoa to Hue through the weekend, with some areas expected to receive more than 100 mm of additional precipitation. The same source indicated that El Niño is likely to reduce rainfall in central and southern Vietnam later in 2026 by 10 % to 50 %, potentially affecting 350,000 ha of rice in the Mekong Delta and causing severe water shortages in the central highlands, Vietnam’s largest coffee-growing region.
What’s Next – Expected Weather and Ongoing Relief Efforts
Authorities plan to maintain the mobilised emergency personnel while monitoring the forecasted storms. Continued rain and the projected El Niño impact suggest that flood-related disruptions may persist into the coming weeks, prompting further assessments of agricultural and infrastructure damage.
