POST-TROPICAL DEPRESSION 11 (HONDE)

全球热带气旋监测公报
预报：宋佳凝 签发：钱奇峰 2025 年 03 月 05 日 10 时
“洪德”向偏南方向移动
时 间：5日08时（北京时）
海 域：南印度洋
命 名：“洪德”，HONDE
中心位置：南纬31.8度、东经49.0度
强度等级：强热带风暴
最大风力：10级（25米/秒，相当于我国的强热带风暴级）
中心气压：985百帕
参考位置：马达加斯加陶拉纳鲁南偏东方向约780公里的洋面上
变化过程：过去24小时，“洪德”强度维持不变
预报结论：“洪德”将以每小时20-25公里的速度向偏南方向移动，强度逐渐减弱。
（这是关于“洪德”的最后一期监测公报）
