Co To Island: record high tide, water level rises more than 4m

At 2:20 p.m., Ms. Le Ngoc Han, Party Secretary of Co To Special Zone (Quang Ninh Province), said that the circulation after storm No. 3 caused a record high tide. The water level was about 4.2 meters in the sea area in front of the Uncle Ho monument square.

"This is something that has never happened in this area. Locals call this the "Southern wave" phenomenon, where the South wave meets the South wind. The high tide starts at 12:30 p.m., and the water rises to create the highest waves at around 2 p.m.," said Ms. Han.

Currently, there is no rain on the island, but there are still strong winds, with waves hitting the embankment at times as high as 2-3 meters. The authorities of the Co To Special Zone are constantly patrolling the coastal road, deploying plans to ensure the safety of the people.

"According to local people's experience, the water will recede after 1 hour. The phenomenon of high tide is an unusual development that risks affecting the sea dike in this area.

Faced with the above developments, Co To special economic zone has taken immediate action to assess the impact and propose solutions to ensure safety," Ms. Han informed.
