In January 2024, the Chongqing Meteorological Observatory issued a Yellow Warning for Road Ice, alerting residents to potential traffic hazards caused by freezing rain and snow. According to the warning, high-altitude areas such as Chengkou, Wuxi, and Wulong are expected to experience road icing within the next 24 hours, which could significantly impact transportation. A yellow warning is classified as a Level-3 alert, indicating moderate risk that warrants public attention and preparedness from relevant authorities.Road ice forms when rain or melted snow rapidly freezes under sub-zero temperatures, greatly increasing the risk of vehicle skidding, longer braking distances, and traffic accidents. The meteorological department advises drivers to reduce speed and maintain safe following distances, while pedestrians—especially the elderly and children—are encouraged to limit outdoor activities and avoid walking on icy surfaces. In response, traffic management and municipal departments have activated emergency protocols, intensifying road inspections and de-icing operations to ensure safe passage on major thoroughfares and critical zones.This warning also highlights the growing frequency of extreme weather events, underscoring the need for cities to strengthen their preparedness and response systems for cold, snowy, and icy conditions, thereby enhancing urban resilience and public safety.
2024年1月，重庆市气象台发布道路结冰黄色预警，提醒市民注意低温雨雪天气可能带来的交通安全隐患。根据预警信息，重庆部分高海拔地区，如城口、巫溪、武隆等地，未来24小时内可能出现对交通有影响的道路结冰现象。黄色预警属于三级预警，表示影响程度中等，需引起公众和相关部门的重视。道路结冰通常由降雨或融雪在低温条件下迅速冻结形成，极易导致车辆打滑、制动距离延长，甚至引发交通事故。气象部门建议，驾驶人员应减速慢行，保持安全车距；行人尤其是老人和儿童应尽量减少外出，避免在结冰路面行走。同时，交管、市政等部门已启动应急响应机制，加强道路巡查与除冰作业，确保城市主干道和重点区域通行安全。此次预警也反映出近年来极端天气事件频发的趋势，提醒各地需进一步完善低温雨雪冰冻灾害的防范与应对体系，提升城市韧性与公共安全水平。
