In January 2024, the Beijing Meteorological Observatory issued a blue alert for heavy snow—the lowest level in China’s meteorological disaster warning system, yet still indicating snowfall that could disrupt transportation, agriculture, and daily life. According to the criteria, certain areas of Beijing are expected to receive more than 4 millimeters of snowfall within the next 24 hours, or snow has already begun falling with accumulating depth likely to continue. The blue alert advises the public to stay warm, limit non-essential outdoor activities, and be aware of secondary hazards such as icy roads and reduced visibility. In response, relevant authorities have activated emergency protocols, enhancing snow removal on roads, adjusting public transit schedules, and inspecting power infrastructure to maintain normal city operations. Residents are encouraged to monitor official media outlets and weather apps for real-time updates and plan travel accordingly to ensure safety.
2024年1月，北京市气象台发布暴雪蓝色预警，这是中国气象灾害预警信号中的最低级别，但仍意味着可能出现对交通、农业和市民生活造成一定影响的降雪天气。根据预警标准，预计未来24小时内北京部分地区将出现4毫米以上的降雪量，或已出现降雪且积雪深度可能持续增加。蓝色预警提示公众注意防寒保暖，减少不必要的户外活动，并关注道路结冰、能见度降低等次生风险。同时，相关部门已启动应急响应机制，加强道路除雪、公共交通调度及电力设施巡检等工作，以保障城市正常运行。市民可通过官方媒体、气象APP等渠道及时获取最新天气信息，合理安排出行计划，确保安全。
