On the afternoon of October 12, through monitoring satellite cloud images, lightning location images and weather radar images, it was shown that convective clouds still exist and develop in the areas of Tay Ninh, Dong Nai, Ho Chi Minh City, Binh Duong, Binh Phuoc, Long An, Dong Thap, Tien Giang...
In the next 4 hours, these convective clouds will continue to cause showers and thunderstorms in the above mentioned area, which may then expand to neighboring areas. During the thunderstorms, there is a possibility of tornadoes, lightning, hail and strong gusts of wind, flash floods on small rivers and streams, and landslides on steep slopes.
Regarding high tides, in the past 12 hours, water levels at stations downstream of the Saigon - Dong Nai river system have risen rapidly and are currently still low. Water levels at stations downstream of the Saigon - Dong Nai river will rise rapidly in the next 5 days.
By October 16, the highest tide of the day may reach approximately level III. The highest tide of this period is likely to appear on October 19-21 (ie September 17-19 of the lunar calendar).
This is the high tide period of the year, we need to be on guard against heavy rain combined with high tide causing flooding in low-lying areas, riverside areas affecting traffic and socio-economic activities in the Ho Chi Minh City area.
In the coming days, the cold continental high pressure will be weakly strengthened to the East, then stabilize. High-altitude easterly wind disturbances will remain in the Southern region. Northeasterly winds will operate at weak intensity in the Southern sea areas.
From 72 hours to the 10th day, the continental cold high pressure has a stable intensity, gradually weakening from around October 14-15. The equatorial low pressure trough around October 15-16 tends to operate well again and slowly lift its axis to the North. The upper easterly wind disturbance operates well in the Southern region.
Therefore, the Southern region has rain, moderate rain and thunderstorms, locally heavy to very heavy rain.
