In the afternoon of June 1, monitoring on satellite cloud images, weather radar images and lightning positioning showed that the convective cloud area is developing strongly, causing thunderstorms with lightning in many areas of Long Truong, Binh Trung and Phuoc Long wards.
In the next 3 hours, convective clouds will continue to develop, causing showers and thunderstorms with lightning in the above areas, then it is likely to expand to Long Phuoc, Tang Nhon Phu wards and neighboring areas. Common rainfall is from 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 at level 5-7 (8-17 m/s). Heavy rain can cause localized flooding in low-lying areas.
The weather pattern causing thunderstorms is due to a low pressure trough with its axis passing through the Southern - South Central region, combined with southwest winds operating at medium intensity in the Southern sea area.
Forecast for the next 24-48 hours, the low pressure trough through the South Central region tends to gradually raise its axis to the North and weaken. Southwest winds continue to operate with moderate to strong intensity. Above, the subtropical high pressure with its axis through the North maintains a stable state.
In the next 3-10 days, the low pressure trough will continue to raise its axis to the North and gradually weaken. Southwest winds will maintain medium intensity, while the subtropical high pressure in the southern branch tends to raise its axis across the South and expand back to the West.
Due to the influence of the current weather pattern, from now until June 3, Ho Chi Minh City area will continue to experience moderate to heavy rain with thunderstorms. Total rainfall is commonly from 80-130 mm, with some places over 130 mm.
From 7:00 AM on June 3rd to 7:00 AM on June 4th, heavy rain in Ho Chi Minh City and southern provinces and cities tends to gradually decrease. Total rainfall is commonly from 20-40 mm, some places may exceed 50 mm.
Rainstorms accompanied by tornadoes, lightning, hail and strong gusts of wind can affect agricultural production, causing trees to fall, damage to houses, traffic works and infrastructure. In addition, heavy rain is at risk of causing localized flooding, affecting traffic, living and production activities in many areas.
