Floods upstream will increase again due to the impact of storm No. 13.

Rainfall due to storm No. 13 in the lower Mekong River basin was quite high on November 7-8, causing the water level of the Mekong mainstream to tend to rise again.

According to the Southern Institute of Water Resources Planning, rain due to the impact of storm No. 13 (Kalmaegi storm) occurring in the lower Mekong River basin will be quite high on November 7-8, 2025. It is predicted that the water level on the Mekong mainstream at Kratie station will tend to increase again next weekend.

High tides are forecast to continue to increase in the next 3 to 4 days, combined with upstream floods still at high levels and forecast to increase again, so it is predicted that the water level of the Mekong River at Tan Chau and Chau Doc will tend to increase slightly.

Flood water levels in the upper Mekong Delta remain quite high and will increase slightly with the tide next week, so there is still a risk of insecurity in some low-elevation or degraded areas in the central area of ​​Dong Thap Muoi (DTM) and a risk of flooding due to high tides in some areas along the main rivers.

The Southern Institute of Water Resources Planning recommends that localities in the central region of the Mekong Delta continue to closely monitor water level developments next week in low-elevation or degraded areas (still under cultivation) to have timely response solutions.

Localities along major rivers such as the old Long Xuyen city area in An Giang province need to be on guard against the risk of flooding that may occur due to increased high tides next week, especially from now until November 9, 2025.

Water levels at stations in the central Mekong Delta region continue to rise and reach the peak of the high tide period in the middle of the 9th lunar month on November 6-7, 2025. The peak water level is generally 0.1-0.3 m above alert level three (BĐIII). In particular, at My Thuan station ( Vinh Long province), the peak water level is forecast to exceed BĐIII by 0.30-0.45 m.

The Southern Institute of Water Resources Planning recommends that localities in the central region of the Mekong Delta need to be on guard and proactively develop response plans to the high risk of flooding that will occur in the next 10 days due to the impact of rain, floods, and high tides, especially from now until November 9, 2025. In particular, the most serious risk of flooding is expected to occur in the central urban areas of Can Tho city, Vinh Long province, and the area between the Tien and Hau rivers in Dong Thap province.

Water levels at coastal stations in the Mekong Delta in the East Sea continue to rise and reach the peak of the high tide period in the middle of the 9th lunar month on November 7-8, 2025, with peak water levels at a common high level on BĐIII from 0.05-0.30 m.

Water levels at stations in the western coastal area will increase again and reach the peak of the high tide period in the middle of the 9th lunar month on November 8-9, 2025, with the peak water level at a common high level on BĐIII from 0.05-0.35 m.

The Southern Institute of Water Resources Planning recommends that localities in the coastal areas of the Mekong Delta, especially residential areas and shrimp-rice production areas with low-lying terrain along the main rivers such as the central area of ​​Ca Mau province, the Northern Ca Mau irrigation sub-regions, the area within the Quan Lo - Phung Hiep irrigation system and the Ganh Hao riverside area in the two provinces of Ca Mau and Bac Lieu (old), need to be on guard and proactively develop response plans to the high risk of flooding that will occur in the next 10 days due to the impact of high tides and heavy rain, especially from now until November 9, 2025.
