According to satellite cloud images, weather radar images and lightning positioning data, convective clouds are developing, causing showers with thunderstorms and lightning in many areas of Ho Chi Minh City.
In the next 3 hours, convective clouds will continue to develop, causing showers, thunderstorms, lightning in wards and communes such as Ben Thanh, Cho Lon, Tan Thuan, Tan My, Tan Hung, Phu Dinh, Dien Hong, Ben Cat, Binh Co, Tan Uyen, Binh Khanh, An Thoi Dong, Bac Tan Uyen, Phu Giao, Phuoc Hoa, An Long, Bau Bang and Thanh An. After that, the thunderstorm area is likely to expand to neighboring areas.
Common rainfall is 5-30mm, in some places over 40mm. During thunderstorms, people need to be wary of tornadoes, lightning and strong gusts of wind at level 5-7, equivalent to about 8-17m/s. Heavy rain can also cause localized flooding in low-lying areas with poor drainage.
According to the meteorological agency, the current thunderstorm pattern is a tropical convergence zone with its axis passing through the South, combined with the southwest monsoon in the South with weak to moderate intensity and strong wind convergence activity in the area.
From 20-24/9, the intertropical convergence zone continues to have its axis passing through the South. The weather in the area is generally cloudy, with widespread rain, scattered moderate rain and thunderstorms, with heavy to very heavy rain in some places. Moderate rain and heavy rain mainly concentrated in the late afternoon and night.
In thunderstorms, it is necessary to prevent tornadoes, lightning and strong gusts of wind. In urban areas, people also need to pay attention to the risk of localized flooding due to heavy rain, especially in low-lying areas and places with poor drainage systems.
In the morning, some places at times have reduced clouds, reduced rain and light sunshine. The highest temperature in the whole area is commonly 29-32 degrees C.
From September 25-27, when the tropical convergence zone tends to gradually raise its axis to the North, the South still maintains rain in many places but rainfall tends to decrease. The area has showers in many places, scattered moderate rain and thunderstorms, with heavy rain in some places; especially the East may experience very heavy rain locally.
By September 28-30, the weather in the South tends to decrease in rain, and the number of sunny hours increases. Rain mainly appears in the afternoon and evening, with scattered rain, in some places moderate rain, and locally heavy rain.
