In the afternoon of September 16, monitoring on satellite cloud images, weather radar images and lightning positioning showed that convective clouds are developing, causing rain with thunderstorms and lightning in many areas of Ho Chi Minh City.
Areas with thunderstorms include Saigon ward, Vinh Hoi ward, An Khanh ward, Tan My ward, Tan Hung ward, Phu Dinh ward, Binh Dong ward, Ly Nhon, An Thoi Dong commune, Dien Hong ward, Hiep Binh ward, Tan Binh Industrial Park, Vinh Tan ward, Nhuan Duc commune, Thai My commune, An Nhon Tay commune, Xuyen Moc commune, Binh Chau commune, Hoa Hoi commune, Binh Khanh commune and Phu My ward.
In the next 3 hours, convective clouds will continue to develop, causing showers with thunderstorms and lightning in the above areas and possibly expanding to neighboring areas.
Common rainfall is 5-20 mm, in some places over 30 mm. During thunderstorms, it is necessary to watch out for tornadoes, lightning, hail and strong gusts of wind of about level 5-7, equivalent to 8-17 m/s. Heavy rain is likely to cause localized flooding.
Weather pattern forecast for the next 24-48 hours, the intertropical convergence zone with its axis passing through the Central region gradually strengthens and lowers its axis to the South. Above, the subtropical high pressure branch in the South gradually weakens. Southwest monsoon is gradually becoming stronger in the Southern region.
Weather pattern forecast for the next 3-10 days, the intertropical convergence zone continues to gradually strengthen, combined with upper-level wind convergence passing through the South. Southwest monsoon has average intensity.
Therefore, from September 18-24, Ho Chi Minh City and southern provinces and cities are likely to experience moderate rain, heavy rain to very heavy rain. Total rainfall is commonly 150-300 mm, with some places over 300 mm.
It is necessary to prevent the possibility of heavy rain causing flooding in low-lying areas, urban areas, industrial parks, riverside areas and canals. In thunderstorms, there is a possibility of tornadoes, lightning, hail and strong gusts of wind.
