Ho Chi Minh City is about to have widespread rain for many days

According to the 10-day weather forecast for Ho Chi Minh City (August 12-22) from the Southern Vietnam Regional Meteorological and Hydrological Station, the low-pressure trough with its axis passing through Northern Vietnam is persisting. The Southwest monsoon maintains a moderate intensity over the southern sea areas.

At higher altitudes, the subtropical high-pressure system is weakening, but from around August 13-14 it is likely to strengthen again, encroaching westward and slowly shifting its axis northward.

From approximately August 14-18, a convergence zone of winds will exist at the 500mb level over the Southern region of Vietnam.

Therefore, this meteorological agency forecasts that in Ho Chi Minh City, the frequency of thunderstorms is likely to increase again over the next 10 days.

At the same time, the National Center for Hydro-Meteorological Forecasting also predicted that from August 11th to September 10th, the Southwest monsoon in the South is likely to continue causing many days of showers and thunderstorms in the Central Highlands and Southern Vietnam, with some days experiencing strong thunderstorms accompanied by heavy rain, mainly concentrated in the late afternoon and evening.

Specifically, this evening (August 12th), the area will experience scattered showers and thunderstorms in some places; from tomorrow evening onwards, there will be continuous scattered showers and thunderstorms, with localized moderate to heavy rain.

The meteorological agency predicts that over the next month, total rainfall in the Central Highlands and Southern Vietnam will be 5-15% higher than the multi-year average for the same period.

During thunderstorms, be aware of the possibility of accompanying extreme weather phenomena such as lightning, tornadoes, and strong gusts of wind, which pose a danger to road users and those working outdoors. Be prepared for heavy rain causing localized flooding in low-lying areas, riverside areas, and urban centers.

Furthermore, over the next month, the tropical convergence zone will continue to be active and has the potential to form tropical depressions/storms in the South China Sea. The tropical convergence zone will cause strong southwest monsoon winds in the southern sea areas, requiring precautions against strong winds and high waves affecting maritime activities and fishing operations.

Previously, the National Center for Hydro-Meteorological Forecasting assessed that provinces and cities in the Central Highlands, Southern Vietnam, and South Central Vietnam experienced an unusually heavy month (July 2023).

Accordingly, due to the intensified activity of the Southwest monsoon, this area experiences widespread thunderstorms for many days throughout the month. In particular, the latter half of the month sees continuous moderate to heavy rainfall across the entire region, with some areas experiencing very heavy rain.

The total rainfall in July in this area was 50-100% higher than the multi-year average, and in some places even over 100%. Notably, some locations recorded daily rainfall and total monthly rainfall exceeding historical values for the same period in July.

Northern and Central Vietnam will experience heavy rainfall over the next month.

During the period from August 11th to September 10th, total rainfall across most parts of the country will be 5-15% higher, especially in the North and Central Central regions, where it will be 15-25% higher than the average for the same period. There is a possibility of 1-2 typhoons and tropical depressions forming in the East Sea.
