Meanwhile, according to the Southern Hydrometeorological Station, the equatorial low pressure trough with its axis at about 7-10 degrees North latitude combined with high-altitude easterly wind disturbances is affecting and causing rain in the Southern region. Total rainfall in the first 10 days of October is generally from 70 - 170 mm, approximately equal to or higher than the average of many years.

In the 10 days of mid-October (from October 10 to 20), the low pressure trough is likely to become active again. The weather in the area is generally rainy, scattered showers in many places. Beware of the possibility of widespread rain with some places having moderate, heavy to very heavy rain lasting for a few days. Beware of thunderstorms, tornadoes, lightning, and gusts of wind that may appear during thunderstorms. Total rainfall is generally higher than the average of many years in the same period, from 90-160mm.

During the last 11 days of October, the Southern region is mainly affected by the southern edge of the continental cold high pressure tongue and the northern edge of the low pressure trough with an axis at about 4-7 degrees north latitude; the wind changes to the northeast with weak to moderate intensity. During this time, the East Sea is likely to have storms or tropical depressions causing widespread rain in the area for a few days. The total rainfall during this time will be higher than the average of many years in the same period, commonly from 70-100mm.

Thus, in the middle and end of October, Ho Chi Minh City and the southern provinces and cities are likely to continue to experience widespread heavy rains. This year's rainy season is likely to end approximately 5-10 days later than the average of many years, and will generally end around mid-December.

It is forecasted that in the first half of November, there will also be 1-2 widespread rains, but these rains will be generally small to moderate in amount, and heavy rain will no longer be common.
