近日，河南省气象台发布低温蓝色预警，提醒公众注意防范持续低温天气可能带来的不利影响。根据预警信息，未来48小时内，河南多地最低气温将降至零下10℃以下，部分地区伴有大风，体感温度更低，易引发冻伤、道路结冰等次生灾害。低温蓝色预警属于中国气象灾害预警信号中的第四级（最低级别），但仍需引起足够重视，尤其对农业、交通、能源供应及户外作业等领域可能造成一定影响。气象部门建议居民注意防寒保暖，尤其是老人、儿童和体弱人群应减少外出；农业方面需加强设施大棚的保温措施，防止作物受冻；交通运输部门应提前做好除冰融雪准备，确保道路安全畅通。此外，公众应关注最新天气预报和预警信息，合理安排出行计划，确保人身与财产安全。
Recently, the Henan Provincial Meteorological Observatory issued a blue alert for low temperatures, urging the public to take precautions against potential hazards caused by prolonged cold weather. According to the warning, over the next 48 hours, minimum temperatures in many areas of Henan will drop below minus 10°C, with strong winds in some regions making the perceived temperature even lower. This increases the risk of frostbite and icy roads. In China’s meteorological warning system, a blue alert is the lowest (Level IV) of four severity levels, but it still warrants attention—particularly as it may impact agriculture, transportation, energy supply, and outdoor operations. Authorities recommend that residents dress warmly and limit outdoor exposure, especially vulnerable groups such as the elderly, children, and those in poor health. Farmers are advised to reinforce insulation in greenhouses to protect crops from freezing. Transportation departments should prepare de-icing and snow-melting measures to maintain safe road conditions. The public is also encouraged to stay updated with the latest forecasts and warnings to plan travel accordingly and ensure personal and property safety.
