At noon on October 15, thunderstorms occurred widely in the Southern region such as Dong Nai, Ho Chi Minh City, Ba Ria - Vung Tau, Binh Duong, Long An, Tien Giang, Dong Thap, Ben Tre, Tra Vinh, An Giang, Ca Mau...
From now until the next 4 hours, these convective clouds will cause showers and thunderstorms in the above mentioned area, then continue to develop and expand, causing rain in neighboring provinces such as Binh Phuoc, Vinh Long, etc. During thunderstorms, there is a possibility of tornadoes, lightning, hail and strong gusts of wind.
The thunderstorms are caused by stable continental cold high pressure. The equatorial low pressure trough has an axis of about 7-10 degrees North latitude. The disturbance of the East wind above affects the weather in the South.
In the coming days, the continental cold high pressure will slowly weaken. The equatorial low pressure trough will have little change in position and intensity. The subtropical high pressure will move westward with an axis through the North. The high-altitude easterly wind disturbance will remain in the South.
Around October 18-19, the continental cold high pressure will strengthen again in the North of our country. The equatorial low pressure trough around October 18-19 will tend to operate well again, slowly lifting its axis to the North and is located at about 7-10 degrees North latitude. The high-altitude East wind disturbance will operate well and remain in the Southern region.
Therefore, widespread thunderstorms are still occurring in the Southern region. During thunderstorms, beware of tornadoes, hail and strong gusts of wind of about level 5-7 (8-17m/s), heavy rain causing localized flooding.
