Ho Chi Minh City continues to face significant challenges from heavy rainfall and urban flooding, which have impacted city infrastructure and the local economy. Recent weather patterns, including heavy rains and high tides, caused widespread flooding that disrupted transportation for 13 out of 14 days in late September and early October.

In early October, prolonged flooding in residential alleys and major thoroughfares, such as Phan Huy Ich and Pham Van Dong, disrupted daily life. Residents reported vehicle damage, property loss, and the necessity of temporarily relocating to hotels as water remained stagnant for several days. In areas like Tan Vinh Loc, the depth of the water has forced residents to use boats for daily transportation as local drainage systems struggle to cope.

Beyond the city, heavy rainfall and rising tides have caused widespread flooding across other Vietnamese regions. In Lam Dong province, intense storms caused significant flooding in Bao Lam and Bao Loc, leading to the evacuation of approximately 40 households to community halls. Water levels reached up to 1.2 meters, causing heavy damage to the agricultural sector, particularly to high-tech rose gardens and greenhouse crops in Da Lat.

In Dong Nai, flooding near the Buong River has affected hundreds of households. Authorities have cited a combination of upstream rainfall and construction-related obstructions from the Bien Hoa-Vung Tau expressway project as factors that have hindered natural drainage and exacerbated the situation.

Authorities have issued urgent directives to manage high tides and heavy rainfall. Forecasts indicate the highest tidal peak of 2026 will occur between October 27 and 29. In response, the Ho Chi Minh City People's Committee has ordered 24/7 emergency readiness and is moving forward with long-term drainage and anti-flooding infrastructure projects.
