On October 21, the Liaoning Provincial Ocean Warning and Monitoring Center issued a level IV blue alert for storm surges at 2 PM, forecasting that coastal areas in Liaoning will experience storm surges of 40 to 90 centimeters.
Storm surges are defined as disasters caused by intense weather systems such as typhoons, temperate cyclones, and cold fronts, which can lead to abnormal sea level changes and result in significant loss of life and property. These events are also referred to as “storm surges,” “storm tsunamis,” “meteorological tsunamis,” or “wind tides.”
According to the warnings, due to the influence of cold air, it is expected that from the afternoon of October 21 to the afternoon of the 22nd, storm surges of 40 to 90 centimeters will affect the Liaoning coastline. The Donggang tide station is anticipated to reach warning levels during the night of the 21st, while the Laohutan tide station is expected to see similar levels in the early hours of the 22nd. The tide stations in Bayuquan and Huludao are projected to reach alert levels by the morning of the 22nd. Cities including Dandong, Dalian, Yingkou, Panjin, Jinzhou, and Huludao are under blue alert for storm surges.
At 4 PM on the same day, the monitoring center also issued a blue warning for high waves: it is expected that from the night of the 21st into the day of the 22nd, the Bohai Sea and northern Yellow Sea will experience wave heights of 2.5 to 3.5 meters. In the coastal waters near the southern part of the Liaodong Peninsula, waves are expected to reach 2.0 to 3.0 meters, marking a blue warning level for those areas.
Officials from the Liaoning Provincial Ocean Warning and Monitoring Center are urging coastal relevant departments to reinforce offshore aquaculture facilities, conduct inspections and maintenance of sea walls and sluices, and effectively secure vulnerable and high-risk areas. They also emphasize the importance of safe operations at ports and terminals and advise coastal visitors to prioritize their safety during this time.
