According to the Southern Hydrometeorological Station, the weather pattern forecast for the next 24-48 hours is that the low pressure trough with its axis through the North will gradually move southward, followed by the formation of a tropical convergence zone with its axis through the North and North Central regions.
Southwest monsoon has moderate to strong intensity. Subtropical high pressure, the northern branch encroaches westward, the southern branch lowers its axis southward. Upper-level wind convergence works better in the Southern region.
Therefore, on August 18, the weather in the South is generally cloudy, sometimes less cloudy and sunny. The highest temperature fluctuates from 29-32 degrees Celsius, especially in the Lam Dong plateau area at 28-31 degrees Celsius.
Due to stronger upper-level wind convergence, thunderstorms tend to increase. At noon, afternoon and evening of August 18, many places will experience rain, scattered moderate rain and thunderstorms, with heavy rain in some places. During thunderstorms, it is necessary to watch out for tornadoes, lightning and strong gusts of wind.
It is noteworthy that the eastern provinces are likely to experience more heavy rain than the Mekong Delta, with a probability of rain of about 20-50%.
In the 2 days of August 19-20, rain tends to decrease in both area and amount. Showers and thunderstorms still appear sporadically in the late afternoon and evening, mainly concentrated in the eastern provinces, with moderate rain in some places, locally heavy rain, with a probability of rain of about 10-30%.
In the Mekong Delta provinces, thunderstorms are forecast to appear on about 1/3 of the area, mainly light to moderate rain and little chance of heavy rain.
