On the afternoon of December 12, satellite cloud images, weather radar images and lightning positioning showed that thunderstorms were developing and causing rain with thunderstorms and lightning in the areas of Binh Chanh, Nha Be, and Thu Duc City.
In the next 0 - 3 hours, thunderstorms will continue to develop, causing showers, accompanied by thunderstorms and lightning in the above districts, then expanding in the South-Southeast - North-Northwest direction to other neighboring areas such as the central area, Go Vap, District 7, 12,...
Rainfall is generally from 5-15 mm, in some places over 20 mm. During thunderstorms, beware of tornadoes, hail and strong gusts of wind around level 5-7 (8-17 m/s).
The thunderstorms are caused by the continental cold high pressure continuing to strengthen to the South. Above, the subtropical high pressure has an axis over the North Central region, the equatorial low pressure trough has an axis at about 5-8 degrees North latitude, and the easterly wind disturbance above is more active.
Weather forecast for the next 24-48 hours, the continental cold high pressure continues to strengthen to the South. Above, the subtropical high pressure with an axis through the North Central region is stable.
The equatorial low pressure trough located at about 4-7 degrees North latitude continues to maintain. The upper easterly wind disturbance is active well over the Southern region. The northeasterly wind in the offshore waters of the Southeast region is moderate to strong.
The continental cold high pressure continues to strengthen after having a stable intensity. From December 16, it will gradually weaken. Around December 18-19, it is likely to weakly strengthen again in the North of our country.
Above, the subtropical high pressure will lower its axis to the South through the Central - South Central regions. From around December 16-17, it will weaken in intensity and gradually withdraw its circulation to the East.
The equatorial low pressure trough gradually moves southward and the upper easterly wind disturbance gradually weakens. The northeasterly wind in the offshore waters of the Southeast is strong.
Therefore, the Southern region is likely to last from now until the end of December 15. Be careful during thunderstorms with the possibility of tornadoes, lightning and strong gusts of wind.
