The National Marine Environmental Forecasting Center has recently issued a blue alert for high waves, warning of potentially hazardous sea conditions in affected waters and urging heightened vigilance. Under China’s Marine Disaster Emergency Response Plan, wave alerts are categorized into four levels: blue, yellow, orange, and red, with blue being the lowest. A blue alert indicates that moderate to large waves between 2.5 and 3.5 meters are expected within the next 24 hours, which may pose risks to marine operations, aquaculture, coastal tourism, and the navigation of small vessels.This alert is primarily triggered by cold air masses or the outer bands of tropical cyclones, leading to increased wind speeds and wave heights in parts of the East China Sea and the northern South China Sea. Relevant authorities have already notified coastal regions to enhance patrols, suspend high-risk maritime activities, and advised fishermen to return to port for shelter while discouraging tourists from visiting vulnerable coastal areas.Although a blue alert signifies relatively low risk, the public should not become complacent. The forecasting center will continue monitoring sea conditions and issue timely updates. Maritime stakeholders and the general public are strongly encouraged to closely follow official forecasts and warnings, and to adjust travel and operational plans accordingly to ensure safety and minimize potential losses.
国家海洋预报台近日发布海浪蓝色警报，提醒相关海域可能出现大浪过程，需加强防范。根据《海洋灾害应急预案》，海浪警报分为蓝、黄、橙、红四个等级，蓝色为最低级别，表示未来24小时内受影响海域将出现2.5至3.5米的中到大浪，可能对海上作业、渔业养殖、滨海旅游及小型船只航行安全构成一定影响。此次警报主要受冷空气或热带气旋外围影响，导致东海、南海北部等部分海域风力增强，浪高增大。相关部门已通知沿海地区加强巡查，暂停高风险海上活动，并建议渔民及时回港避风，游客避免前往危险海岸区域。虽然蓝色警报属于较低风险等级，但公众仍不可掉以轻心。海洋预报台将持续监测海况变化，及时更新预警信息。建议涉海单位和公众密切关注官方发布的最新预报与警报，合理安排生产与出行计划，确保人身与财产安全。
