In the afternoon of May 3, through monitoring satellite cloud images, weather radar and lightning positioning data, it was shown that thunderstorm clouds are developing strongly, causing showers accompanied by thunderstorms and lightning in provinces and cities including: Ca Mau, An Giang, Can Tho, Dong Thap, Ho Chi Minh City and Dong Nai.
In the next 0-3 hours, thunderstorms will continue to develop, maintain showers with thunderstorms and lightning in the above areas, then tend to expand to neighboring areas. Common rainfall is from 12-60 mm, in some places over 60 mm.
During thunderstorms, it is necessary to be wary of dangerous phenomena such as tornadoes, lightning, hail and strong gusts of wind at level 5-8 (8-21 m/s), and at the same time, be wary of the risk of localized flooding due to heavy rain.
Weather pattern forecast for the next 24-48 hours, hot low pressure from the West connects to a low pressure trough with axis of about 24-27 degrees North latitude, compressed by continental high pressure from the North.
Above, the subtropical high pressure with its axis through the Central region maintains stable intensity, while high-altitude disturbances are active.
Forecast from 3-10 days, the hot low pressure area in the West will continue to connect with the low pressure trough (axe 24-27 degrees North latitude), being compressed and gradually moving southward due to the influence of the continental high pressure in the North. At the same time, another low pressure trough with axis of about 4-7 degrees North latitude is likely to form and gradually raise its axis to the North.
Above, the subtropical high pressure passing through the Central region tends to retreat to the East, with stronger activity in the last days of the period; high-altitude disturbances continue to be maintained.
Therefore, the Southern region is sunny and hot during the day, it is necessary to prevent the risk of fire and explosion and health problems, especially cardiovascular diseases. Rainstorms accompanied by tornadoes, lightning, hail and strong gusts of wind can affect agricultural production, causing trees to fall, damage to houses and infrastructure works.
