Monitoring on satellite cloud images, weather radar images and lightning positioning shows that convective clouds are developing, causing rain with thunderstorms and lightning in many areas of Tan Nhut, Binh Hung, Binh Khanh, Long Hoa, Dau Tieng and Minh Thanh communes.
In addition, the thunderstorm cloud area in the Tay Ninh area is developing strongly and tends to move in the Southwest - Northeast direction towards Ho Chi Minh City.

Forecast for the next 3 hours, convective clouds will continue to develop, causing showers with thunderstorms and lightning in the above-mentioned localities, then expanding to many other areas such as An Khanh ward, Cau Ong Lanh, Xom Chieu, Tan Hung, Chanh Hung, Ban Co, Binh Tien, Dien Hong, Tan My, Phu Dinh, Saigon, Binh Tan...
Common rainfall is from 5-25 mm, in some places over 30 mm. During thunderstorms, it is necessary to watch out for tornadoes, lightning, hail and strong gusts of wind at level 5-7 (8-17 m/s). Heavy rain is likely to cause localized flooding in low-lying areas.
The weather pattern causing thunderstorms is due to a low pressure trough with its axis passing through the South - South Central region combined with southwest winds operating at medium intensity over the Southern sea area.
