In the afternoon of July 25, dense black clouds appeared in many areas of Ho Chi Minh City, followed by showers and thunderstorms. The rain came during rush hour, causing traffic on some routes to slow down, and many people had to stop their vehicles to wear raincoats or shelter from the rain.
Monitoring on satellite cloud images, weather radar images and lightning positioning shows that thunderstorm clouds are developing strongly, causing showers with thunderstorms and lightning in many areas of Ho Chi Minh City and Dong Nai, Tay Ninh, Lam Dong, Dong Thap provinces and some neighboring areas.

During thunderstorms, people need to be wary of tornadoes, lightning, hail, strong gusts of wind at level 5-8 (8-21 m/s) and heavy rain causing localized flooding.
The cause of thunderstorms is due to the Southwest monsoon operating with moderate to strong intensity, combined with the south of the low pressure trough with its axis passing through the middle of the East Sea connecting to the storm center operating in the East Sea, creating favorable conditions for convective clouds to develop strongly.
