On the afternoon of May 7, in Ho Chi Minh City, thunderstorms are developing and causing rain with thunderstorms in the Can Gio area, District 6, Thu Duc City.
In the next 0-3 hours, thunderstorms will continue to develop, causing showers, accompanied by thunderstorms and lightning in the above areas, then expanding to other neighboring areas.
Rainfall is generally from 2-15 mm, in some places over 15 mm. During thunderstorms, beware of tornadoes, hail and strong gusts of wind, heavy rain causing local flooding.
The image that causes thunderstorms is caused by a low pressure groove connected to the western low pressure with a axis of 24-28 degrees North latitude to be weak to the south by the continental cold high pressure. The equatorial low pressure groove in the south has axis at about 5-8 degrees North latitude. High pressure on subtropical high pressure has stable intensity through Central Central.
The weather is forecast for the next 24-48 hours, the low pressure groove with a axis of 22-24 degrees north latitude connected to the western low pressure continues to be weak to the south and gradually by the continental high pressure from the North. Facilitating the western low pressure to develop and expand to the southeast to set up the low pressure trench with 25-28 degrees of north latitude.
The equatorial low pressure trough with an axis at about 5-8 degrees North latitude is gradually weakening. The southwest wind is not strong. Above, the subtropical high pressure with an axis through the North and Central Central regions will encroach on the West.
Weather forecast for the next 3 days, the low pressure trough with an axis at about 25-28 degrees North latitude connecting with the hot low pressure area in the West will be compressed to the South and gradually filled by a part of the continental cold high pressure in the North.
The southwest wind will be weak to moderate. Above, the subtropical high pressure will operate stably, weakening from around May 10 and retreating to the East, and will tend to encroach on the West again around May 13-14.
From around May 9-10, the possibility of setting up a low pressure trough in the Northwest - Southeast direction connecting with the low pressure area through the North and the South China Sea will gradually become stronger, dominating the weather in the South.
Therefore, in the coming days, thunderstorms in the South tend to appear more often and more frequently. There are places with moderate rain, heavy rain and thunderstorms, so beware of thunderstorms, tornadoes, hail and strong gusts of wind.
