On the afternoon of June 17, monitoring satellite cloud images, weather radar images and lightning positioning showed that the thunderstorm area was developing and causing rain with thunderstorms and lightning in Binh Chanh area, District 12, Hoc Mon district, Cu Chi district (HCMC). In addition, the developing thunderstorm area in the Dong Nai area is also tending to expand towards Ho Chi Minh 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 to other neighboring areas such as Thu Duc City and central districts of the city. Rainfall is generally from 5-10 mm, in some places over 15 mm. During thunderstorms, beware of tornadoes, hail and strong gusts of wind of about level 5-7 (8-17 m/s), heavy rain causing local flooding.
The thunderstorms are caused by the weakening of the low pressure trough over the North. The southwest monsoon in the South will operate at a weak intensity. Above, the subtropical high pressure will encroach to the West through the South Central region.
Weather forecast for the next 24-48 hours, the low pressure trough with an axis of 22-25 degrees North latitude combined with high-altitude wind convergence will continue through the North and South of China. Above, the subtropical high pressure will continue to encroach to the West and slowly lift its axis to the North. The southwest monsoon will be weak to moderate in the South.
Weather forecast for the next 3-10 days, the low pressure area in the West tends to develop and expand to the East. The southwest monsoon will operate at a weak intensity. Above, the subtropical high pressure tends to encroach to the West and gradually lift its axis to the North.
Therefore, from June 18, thunderstorms will increase again in the Southern region. During thunderstorms, beware of thunderstorms, tornadoes, hail and strong gusts of wind, as well as heavy rain causing flooding.
