Ho Chi Minh City experienced a torrential downpour on the afternoon of October 1, resulting in widespread traffic chaos and difficulties for residents. The rain, accompanied by thunder and lightning, began shortly after 5 PM and persisted for almost two hours, leading to extensive traffic jams in the city center.

By 7 PM, traffic was backed up for over 4 kilometers from the Hang Xanh area to the Saigon Bridge, a critical route connecting the city center to Thu Duc via Vo Nguyen Giap Road and Hanoi Highway. Nearby, Nguyen Huu Canh Street also faced severe congestion.

The heavy rain caused significant delays on several major roads, including Dien Bien Phu and Nguyen Huu Canh, making it challenging for residents to navigate. According to the Southern Meteorological Center, the city is expected to experience heavy rainfall from October 1 to 4, particularly affecting areas such as Go Vap, Cu Chi, Hoc Mon, and the old District 12. Residents have been advised to be cautious of extreme rainfall accompanied by thunderstorms due to thermal convection.

In the aftermath of the rain, many streets were reported to be flooded, with at least 12 roads experiencing significant water accumulation. Phan Huy Ich Street, in particular, saw water levels exceeding one meter, causing buses and vehicles to stall and further exacerbating traffic issues.

On the evening of September 30, the city also faced widespread heavy rain, with recorded rainfall of 136 mm in Le Minh Xuan, 108 mm in Thu Duc, and over 100 mm in other areas. The timing of the rain coincided with rush hour, resulting in deep flooding on many streets and prolonged traffic jams.

As the rain continued, areas near the Saigon River, such as Quoc Huong Street in the old District 2, saw water levels rise nearly a meter, leading to stalled vehicles and residents needing assistance to move home. The region, densely populated and home to many high-rise buildings, is particularly prone to traffic congestion during heavy rains.

Traffic was also heavily impacted on routes leading to Tan Son Nhat Airport, with vehicles at a standstill on Pham Van Dong Road, a vital artery connecting Thu Duc with the airport. The situation was further complicated by a stalled vehicle blocking one lane, causing additional delays.

According to Tran Van Hung, Deputy Director of the Southern Meteorological Center, rainfall is expected to increase in both extent and intensity from October 5 to 6 due to a developing low-pressure system that may strengthen into a tropical convergence zone.
