In the afternoon of June 16, monitoring satellite cloud images, weather radar and lightning positioning data showed that convective cloud areas are developing strongly, causing showers with thunderstorms and lightning in many areas of Ho Chi Minh City and Binh Duong province. Thunderstorms were recorded in Binh Tien, Phu Dinh, Tang Nhon Phu, Dong Hoa, Di An, Tan Dong Hiep wards and Thuong Tan, Bac Tan Uyen, Phuoc Hoa and Xuan Son communes.
In the next 3 hours, convective clouds will continue to develop and expand, causing showers with thunderstorms and lightning in the above-mentioned areas, and also spreading to Tan Uyen, Long Binh, Thu Duc wards and neighboring areas. Common rainfall is from 10-30 mm, in some places over 50 mm.
People need to be wary of dangerous weather phenomena during thunderstorms such as tornadoes, lightning, hail and strong gusts of wind at level 5-7. Heavy rain in a short time can cause localized flooding in low-lying areas, affecting traffic and daily life.
The cause of thunderstorms is due to a low pressure trough with its axis passing through the area 23-25 degrees North latitude connected to the hot low pressure area in the West, combined with the Southwest monsoon operating at medium intensity. Above, the subtropical high pressure with its axis passing through the South Central - Southern region continues to be maintained.
In the next 24-48 hours, the low pressure trough will be compressed and gradually move south under the impact of continental high pressure from the North. Southwest monsoons maintain weak to moderate intensity, while upper-level wind convergence continues to exist, creating favorable conditions for thunderstorms to develop.
From now until about June 25, the low pressure trough passing through the North has a tendency to gradually fill. From June 19, a new low pressure trough connecting to the hot low pressure area in the West will form and expand southeast. Meanwhile, the upper subtropical high pressure is more active before weakening and gradually moving eastward from after June 21. Southwest winds continue to operate at a weak to moderate level, convergence of upper winds will be maintained until the end of June 20.
Due to the impact of the above weather patterns, the Southern region maintains a cloudy state, with showers and thunderstorms in some places during the day, showers and scattered thunderstorms in the late afternoon and evening, and locally heavy rain in some places.
The meteorological agency notes that thunderstorms accompanied by tornadoes, lightning, hail and strong gusts of wind can cause damage to crops, houses, infrastructure and traffic. Prolonged heavy rain also increases the risk of localized flooding, affecting production, travel and people's lives.
