According to the Southern Regional Hydrometeorological Centre, HCM City's weather over the next 10 days will be influenced by a strengthening continental cold high-pressure system extending southwards.
Meanwhile, a subtropical high-pressure system at higher altitudes is expected to move westwards before weakening and retreating eastwards around November 11-12.
Over the next 24-48 hours, disturbances in upper-level easterly winds across southern Vietnam are expected to weaken. However, thunderstorms accompanied by tornadoes, lightning and strong gusts remain possible.
Northeasterly winds are forecast to strengthen over southern waters during the next three to 10 days, reaching moderate to strong levels.
The weather agency warned that thunderstorms and strong winds could damage trees, homes and transport infrastructure, while disrupting production activities.
Localised heavy rain could also cause flooding in poorly drained urban areas, low-lying locations and riverside communities.

Water levels in most rivers and canals are forecast to rise over the next two to three days during the tidal cycle at the beginning of the tenth lunar month, before gradually declining.
The highest tides are expected between November 9 and 11.
At Phu An and Nha Be stations, water levels could reach 1.63-1.68 metres, exceeding alert level three by 0.03-0.08 metres. Peak tides are forecast between 4am and 6am and between 4pm and 6pm.
At Thu Dau Mot Station, levels could reach 1.73-1.78 metres, exceeding alert level three by 0.13-0.18 metres. Peak tides are expected between 5am and 7am and between 5pm and 7pm.
The weather agency urged residents in low-lying and riverside areas to remain alert to flooding, particularly during peak tidal hours.
