Records show that many areas in Ho Chi Minh City experienced heavy rain with thunderstorms, making the sky gloomy and visibility reduced.
Many people said that the rain helped the morning weather become milder than in previous days, but heavy rain at rush hour also caused difficulties for travel.
The Southern Regional Hydrometeorological Station said that through monitoring from satellite cloud images, weather radar and lightning positioning systems, convective clouds are developing strongly and causing thunderstorms in many areas in Ho Chi Minh City and the South. In Ho Chi Minh City, thunderstorms appear in Phu Dinh ward, Dien Hong ward, Phu My ward, Binh Khanh commune, An Thoi Dong commune...
In the next 3 hours, convective clouds will continue to develop, causing showers and thunderstorms in the above areas, then it is likely to expand to neighboring areas. Common rainfall is from 5-20 mm, in some places over 30 mm.
The meteorological agency warns that during thunderstorms there may be tornadoes, lightning, hail and strong gusts of wind at level 5-7, equivalent to 8-17 m/s. Heavy rain in a short time also has the risk of causing localized flooding on many low-lying roads.
The cause of thunderstorms is a low pressure trough with a Northwest - Southeast axis operating through the South Central region, combined with weak to moderate southwest winds over the Southern sea areas.
