According to the Southern Hydrometeorological Station, in the afternoon of September 10, the tropical convergence zone with its axis through the South Central region, combined with the Southwest monsoon operating at medium intensity, created conditions for the formation of strong convective clouds in Ho Chi Minh City.
Through monitoring satellite cloud images, weather radar and lightning positioning systems, the meteorological agency recorded a developing convective cloud area, causing showers with thunderstorms and lightning on a large scale in many wards and communes of Ho Chi Minh City.
The areas being affected include many central wards and eastern, western, and southern areas of the city such as Saigon, Tan Dinh, Ben Thanh, Xuan Hoa, Cho Lon, Binh Phu, Tan My, Tan Hung, Phu Dinh, Binh Dong, Dien Hong, Phu Tho, Gia Dinh, Binh Thanh, Bay Hien, Tan Binh, Tan Son, Tan Son Nhi, Phu Tho Hoa, Long Phuoc, Long Truong, Cat Lai, Binh Trung, An Khanh, Thoi Hoa, An Phu...
