According to the Southern Hydrometeorological Station, the equatorial trough tends to lift its axis northward through the area on this trough, containing many disturbances causing rain.
Disturbances in the easterly wind zone from the southern edge of the subtropical high pressure will operate strongly again and move inland.
The combination of the two conditions will affect the weather in the South, especially Ho Chi Minh City, causing rain to gradually increase from now until November 18. Rain is likely to occur widely, with some places experiencing moderate to heavy rain for a long time.
