On November 20, the highest water level at Long Xuyen station on the Hau River will be recorded at 250cm.

Due to the appearance of tidal peaks in the lower reaches of the Hau River, rising water levels are likely to cause flooding and local inundation in some low-lying areas, riverside areas, canals, ditches, and vulnerable culverts in urban areas in Long Xuyen, Binh Duc, My Thoi wards and My Hoa Hung commune, An Giang province.

According to the warning, Long Xuyen ward is likely to experience flooding and localized waterlogging in the embankment area, along the Hau River, and Rach Gia Long Xuyen canal.

The An Giang Province Hydrometeorological Station also warned that the Hau River area through Long Xuyen Ward has a large width, deep river, strong flow speed and large, deep flooded areas. When strong winds occur, it can create large waves causing erosion and landslides on river banks, canals and ditches. Therefore, the locality needs to have a plan to prevent and combat landslides on river banks, canals and ditches to limit the impact on traffic activities, aquaculture, agricultural production and socio- economic activities of the people.

In the past 24 hours, there has been little rain in Long Xuyen, Binh Duc, My Thoi wards and My Hoa Hung commune. Water levels on Tien and Hau rivers have been slowly decreasing. By the end of November 17, the highest water level on Hau river in Long Xuyen was 234 cm, 16 cm below alert level 3.
