In the afternoon of June 21, according to satellite cloud images, weather radar and lightning positioning data, convective cloud areas are developing strongly, causing showers with thunderstorms and lightning in many areas of Ho Chi Minh City and Binh Duong such as Cau Ong Lanh, Binh Tien, Tan Hung, Phu Dinh, Dien Hong, Dong Hung Thuan, Binh Tan, Tan Tao, Binh Tri Dong, Binh Hung Hoa...

In thunderstorms, it is necessary to be wary of tornadoes, lightning, hail, strong gusts of wind at level 5-7 and the risk of localized flooding in low-lying areas.
Due to the influence of a low pressure trough with an axis of about 24-27 degrees north latitude connected to the hot low pressure area to the West, combined with the Southwest monsoon operating at medium intensity and wind convergence at high altitude, the Southern region is experiencing favorable conditions for thunderstorms to develop.
In the next 24-48 hours, the low pressure trough connecting to the hot low pressure area to the West will continue to be maintained. Southwest monsoon with intensity from weak to moderate and forecast to gradually strengthen from June 22. Above, the subtropical high pressure weakens and gradually withdraws its circulation to the East.
From now until about 10 days, the low pressure trough will continue to develop, expand to the Southeast and is likely to be compressed, gradually moving southward around the 24-25. 6. Southwest monsoon maintains medium intensity, while the subtropical high pressure continues to weaken before tending to encroach back to the West in the last days of the forecast period.
