In the next 24-48 hours, the continental cold high pressure gradually weakens, while the hot low pressure in the West develops, expands to the East and forms a low pressure trough with an axis of about 25-28 degrees North latitude.
Northeast winds maintain average intensity over the sea area in the Southeast region. Above, subtropical high pressure operates more stably over the Southern region.
From 3-10 days, the continental cold high pressure tends to strengthen and deviate to the Southeast of China on the 18th and 22nd. 3. The low pressure trough connected to the hot low pressure to the West continues to be maintained with axis of about 24-27 degrees North latitude.
Above, the subtropical high pressure gradually strengthens, initially passing through the South, then gradually moving up to the Central region at the end of the period. Northeast wind in the sea area in the Southeast region remains at a weak to moderate level.
Therefore, the main weather in the South is sunny during the day, showers and thunderstorms in some places in the evening and at night.
In terms of hydrology, the water level at most stations in the Saigon River is rising rapidly according to the high tide period at the beginning of February (lunar calendar). The highest tide peak in this period is likely to appear on March 20-21. 3.
At Phu An and Nha Be stations: water levels reach about 1.55-1.60 m (approximately or lower than alarm level III by about 0.05 m), appearing at 5-7 am and 5-7 pm.
At Thu Dau Mot station, the water level reached 1.62-1.67 m (approximately or higher than alarm level III by about 0.07 m), appearing at 6-8 am and 6-8 pm.
It is necessary to prevent the risk of flooding in low-lying areas and riverside areas in Ho Chi Minh City.
