On the afternoon of July 25, through monitoring on satellite cloud images, lightning location data and weather radar images, convective clouds continued to develop in the area of Binh Phuoc provinces; Dong Nai; BA Ria Vung Tau; Binh Duong; Tay Ninh; Ho Chi Minh City; Long An; Tien Giang; Ben tre; Tra Vinh; Vinh Long; Soc Trang; Kien Giang; Can Tho and Dong Thap. The cloud nests move from the Southwest to the Northeast.
From now to the next 4 hours, this area of convective clouds will cause showers and thunderstorms in the above area, then may expand to neighboring areas. Dong Nai and Ba Ria - Vung Tau areas may experience rainfall of ~30mm/h. During thunderstorms, there is a possibility of tornadoes, lightning, hail and strong winds.
In the next 24-48 hours, the tropical convergence zone will have an axis through the Northern region. The southwest monsoon operates with moderate to strong intensity. At high altitude, around July 27-28, the subtropical high pressure tends to encroach on the West again.
From 72 hours to 10 days, the tropical convergence zone with an axis through the Northern region gradually weakens. The southwest monsoon operates with moderate to strong intensity until around July 28, gradually decreasing in intensity.
At high altitude, the subtropical high pressure continues to encroach on the West and gradually strengthens, from about July 30, with a horizontal axis across the South Central - Southern region, then gradually lifts the axis to the North.
Therefore, the Southern region has showers and scattered thunderstorms, locally with heavy rain with rainfall from 10-30mm, locally over 70mm.
