On the afternoon of October 11, monitoring satellite cloud images, weather radar images and lightning positioning showed that the area of thunderstorms was developing and causing rain with thunderstorms and lightning in the areas of Can Gio, Binh Chanh, District 12, Hoc Mon District, and Cu Chi District (HCMC). In addition, the thunderstorms that were developing strongly in the Dong Nai area also tended to move towards HCMC.
In the next 0 - 3 hours, thunderstorms will continue to develop, causing showers, accompanied by thunderstorms and lightning in the above districts, then expanding to other neighboring areas such as Thu Duc City, Nha Be, and central districts of the city...
Rainfall is generally from 5-20mm, some places over 30mm. During thunderstorms, beware of tornadoes, hail and strong gusts of wind around level 5-7 (8-17m/s), heavy rain causing localized flooding.
The thunderstorms are caused by stable continental cold high pressure. The equatorial low pressure trough has an axis at about 6-9 degrees North latitude. The high-altitude easterly wind disturbance has a weak impact on the weather in the South.
In the coming days, the continental cold high pressure will weaken in intensity, around October 13 and October 19-20, and will be weakly strengthened again. The equatorial low pressure trough with an axis of 6-9 degrees North latitude will weaken and fade, around October 15-16, the low trough with a position of 7-10 degrees North latitude is likely to be re-established. The high-altitude easterly wind disturbance will continue to operate well and affect the weather in the Southern region.
Therefore, the weather in the area is cloudy most days of the week, with scattered showers in many places with light to moderate rainfall; a few days with heavy rain in the early morning or late afternoon.
During October 11-14 and October 19-20, the sky will be cloudy, sunny during the day, with showers in many places and scattered thunderstorms in the evening. Northeast wind level 3-4 during October 11-12, then the wind will change direction and become weak.
From October 15-18, the sky will be cloudy with widespread rain, with the possibility of rain in the early morning due to the impact of low-level easterly wind disturbances combined with the equatorial low pressure trough. The wind will change direction and be weak to moderate in intensity.
