According to the Southern Regional Hydro-Meteorological Center, Ho Chi Minh City and several southern provinces and cities will continue to receive heavy rain, with some areas experiencing very heavy downpours, for three days, from 11 to 13 September. The most intense rainfall is anticipated from late this afternoon.

Rainfall forecasts for the next 24 hours indicate that the Dau Tieng and Phu Giao areas could record over 130 mm of rain, while Cu Chi, Thu Duc, and Thu Dau Mot are expected to receive around 100 mm. Over 100 mm of rain in a single day is considered rare for urban areas in HCMC.

Tran Van Hung, Deputy Director of the Southern Regional Hydro-Meteorological Center, attributed the heavy rainfall to a tropical convergence zone combined with a strong southwest monsoon.

This period of heavy rain coincides with high tides from 11 to 13 September (the beginning of the 8th lunar month), which could see water levels in some areas approach alarm level 3. This significantly increases the risk of flooding in low-lying regions. Rain is forecast to occur during the afternoon rush hour, so residents should proactively plan their routes and be vigilant against thunderstorms, whirlwinds, lightning, and strong gusts.

On the afternoon of 10/9, heavy rain persisted from approximately 17h until evening, blanketing many parts of Ho Chi Minh City. From 7h to 21h, multiple stations recorded rainfall exceeding 100 mm. Cu Chi registered 127,2 mm, Cat Lai 126,4 mm, Thu Duc 113 mm, and Hoc Mon approximately 104 mm. This event marked the city's heaviest rainfall since the start of the year.

The rain, coinciding with the evening rush hour, led to flooding on over 10 roads and areas, particularly in the eastern, northern, and inner-city districts. Notably affected locations included the An Phu underpass, Do Xuan Hop, Quoc Huong, Xuan Thuy, Thao Dien, To Ngoc Van, Chu Van An, Dien Bien Phu, Dinh Bo Linh, the Thu Duc market area, Hoc Mon market, and the old Mien Dong Bus Station. Water levels in many places rose 30-50 cm, causing numerous vehicles to stall and resulting in prolonged traffic jams.

In Cu Chi and Hoc Mon, areas that recorded the city's highest rainfall, water inundated many homes, washing in trash and plastic bags. Refrigerators, tables, chairs, mattresses, and other household items were soaked and damaged.

The An Phu underpass at the An Phu intersection (formerly Thu Duc City) was flooded about half a meter deep, causing several cars to stall and necessitating rescue vehicles to transport them to garages. In Hiep Binh ward, streets 38 and 40 were also flooded about half a meter deep since yesterday evening. As of this morning, water in some alleys and residential areas had not fully receded, significantly disrupting residents' daily lives.
