High tides in the coastal areas of the North

According to the National Center for Hydro-Meteorological Forecasting, from the evening of December 8 to 9, the water level along the Northern coast is at a high level and tends to change slowly. The highest tide of the day at Hon Dau station (Hai Phong) is likely to reach 4.1 - 4.25m, with the peak tide appearing from 4 to 8am.

Forecasts indicate that from December 10-11, water levels along the northern coast will remain high and are showing a slow downward trend. The highest water level at Hon Dau Island is predicted to reach 4-4.1 meters.

According to hydrological forecasting experts, this is a period of high tides, and low-lying coastal and riverside areas, as well as areas outside dikes, are likely to be flooded for 4-8 hours daily. High tides will slow down the flood drainage process on the river system in the area. In the late afternoon and evening, strong currents flowing offshore when the tide recedes should be anticipated, posing a danger to maritime activities and beach tourism , especially at ports and beaches.

Regarding high tides along the southeastern coast of Vietnam, from the evening of December 8th to 9th, the highest water levels along the eastern coast of the South tend to decrease slowly. The highest daily tide peak at the Vung Tau station is likely to reach 4.2 - 4.3m, occurring between 2 PM and 7 PM and 11 PM and 3 AM.

Forecasts indicate that from December 10-11, the highest daily water levels along the eastern coast of Southern Vietnam will gradually decrease, with the highest daily tide peak at the Vung Tau station likely reaching 3.95-4.1m.

The eastern coastal area of ​​Southern Vietnam needs to be aware of the high risk of flooding and dike breaches in low-lying coastal and riverside areas, as well as areas outside the dikes, affecting transportation, agricultural production, aquaculture, water pollution, and the daily lives of the people.

Hydrological experts note that high tides will slow down the flood drainage process on rivers in the Southeast. Low-lying coastal areas, river banks, and areas outside the dykes in the Southeast are likely to be flooded in the early morning and early afternoon. In addition, high tides during this period also increase saltwater intrusion in the fields.

To proactively respond to and minimize damage caused by major tidal surges and flooding in the coming period, the Department of Dyke Management and Disaster Prevention and Control under the Ministry of Agriculture and Environment requests that affected provinces and cities closely monitor weather forecasts and warnings, and promptly inform local authorities and the public to take proactive preventive measures.

Authorities inspect and review coastal residential areas, dykes, dams, low-lying areas with high risk of flooding to proactively organize the relocation and evacuation of people when situations arise; clear the flow, and promptly handle construction incidents from the first hour.

Provinces and cities are ready to deploy measures to drain water and protect production; reinforce and protect aquaculture ponds; harvest crops and dry crops that are ready for harvest; prevent and combat flooding in urban areas and low-lying areas, ensuring minimal damage; notify owners of water transport vehicles about flooding to proactively take measures to ensure safety for people, vehicles, equipment and works.
