In the afternoon of May 10, monitoring satellite cloud images, weather radar images and lightning positioning showed that the convective cloud area is developing strongly, causing rain with thunderstorms and lightning in many areas of Tan Hung, Phu Dinh, Binh Loi, Tan Nhut, Binh Hung and Nha Be wards and communes.
In the next 3 hours, convective clouds will continue to develop, causing showers with thunderstorms and lightning in the above localities, then it is likely to expand to neighboring areas. Common rainfall is from 5-20 mm, in some places over 30 mm.
During thunderstorms, people need to be wary of tornadoes, lightning, hail and strong gusts of wind at level 5-7 (8-17 m/s). Heavy rain may cause localized flooding in some low-lying areas.
The cause of thunderstorms is the development of the western low pressure combined with wind disturbances at high altitudes.
According to forecasts, in the next 24-48 hours, the continental high pressure will continue to move eastward and gradually weaken, forming a low pressure trough stretching through the area of 24-28 degrees North latitude, connected to the hot low pressure area to the West. The low pressure trough to the South has axis of about 4-7 degrees North latitude, tending to slightly raise to the North and then weaken.
Above, the subtropical high pressure with its axis through the North Central region remains stable, while high-altitude disturbances are weak in the Southern region.
From now until about 10 days, the low pressure trough connecting to the hot low pressure area in the West tends to be compressed and gradually move south due to strengthened continental cold air from the North. Around May 15-16, a low pressure trough is likely to form in the Northwest - Southeast direction through the Central region and the southern sea.
Above, the subtropical high pressure will gradually lower its axis to the South, weaken and slightly retreat to the East; by May 17-18, it may pass through the South Central and Southern regions.
The hot weather in the South at noon and afternoon can increase the risk of fire and explosion and affect health, especially cardiovascular diseases.
In addition, thunderstorms accompanied by tornadoes, lightning, hail and strong gusts of wind can adversely affect agricultural production, causing trees to fall, damage to houses, traffic works and infrastructure.
