Satellite cloud images, weather radar images and lightning positioning data show that convective cloud areas are developing strongly, causing showers with thunderstorms and lightning in many areas of wards and communes of Ho Chi Minh City and neighboring areas.
In the next 03 hours, convective clouds will continue to develop and maintain, causing showers and thunderstorms in the above-mentioned localities, then tend to expand to neighboring areas such as Thoi Hoa, Binh Quoi, Hiep Binh, Linh Xuan, Long Phuoc, Tan Thoi Hiep, Thoi An, Binh Hoa, Tam Binh, Ba Ria, Long Huong, Ben Cat, Long Nguyen, An Thoi Dong, Bac Tan Uyen, Nghia Thanh, Phuoc Thanh, Hoa Hoi, Xuan Son, Hoa Hiep, Hiep Phuoc...
Common rainfall is from 5-25 mm, in some places over 30 mm. During thunderstorms, it is necessary to be wary of dangerous weather phenomena such as tornadoes, lightning, hail and strong gusts of wind at level 5-7 (8-17 m/s). Localized heavy rain may cause flooding in low-lying areas, urban areas and affect traffic.
Weather pattern forecast for the next 24-48 hours, a low pressure trough with an axis of about 24-27 degrees North latitude connected to the hot low pressure area in the West continues to develop and expand to the Southeast. From June 24, this system will be affected by the compression of the continental high pressure mass in the North.
The Southwest monsoon maintains medium intensity. Above, the subtropical high pressure weakens and gradually moves eastward, creating conditions for increased wind convergence at high altitude, favorable for the formation and development of thunderstorm clouds.
Forecast weather trend from 3-10 days, the low pressure trough connecting to the hot low pressure area in the West continues to be compressed and gradually move down to the Northern region. Southwest monsoon maintains average intensity. Above, the subtropical high pressure continues to weaken and gradually recedes to the East; around June 28, there is a tendency to expand back to the West.
From around June 27-28, a low pressure trough is expected to form with the Northwest - Southeast axis passing through the Central and South Central regions. Therefore, thunderstorms in the South tend to increase in both area and amount.
People need to be wary of thunderstorms, tornadoes, lightning, hail and strong gusts of wind that can cause damage to agricultural production, break down green trees, damage houses, infrastructure works and affect traffic. Localized heavy rain is at risk of causing flooding, affecting daily life, production and travel activities.
