台风“玛瑙”位于西北太平洋上
南海热带低压在中南半岛南部减弱消失
一、台风“玛瑙”位于西北太平洋上
今年第20号台风“玛瑙”（强热带风暴级）的中心今天（27日）下午5点钟位于日本东京偏南方向大约1600公里的西北太平洋洋面上，就是北纬21.3度、东经139.6度，中心附近最大风力有11级（30米/秒），中心最低气压为980百帕，七级风圈半径100-250公里，十级风圈半径50-80公里。
预计，“玛瑙”将以每小时15公里左右的速度向北偏东方向移动，强度逐渐增强，最强可达台风级或强台风级（13-14级，38-42米/秒）。“玛瑙”未来将趋向日本东南部洋面，并逐渐变性为温带气旋，对我国无影响。
二、南海热带低压停止编报
南海热带低压今天（27日）早晨登陆越南以后，持续西行减弱，目前已经很难确定其环流中心，中央气象台下午2点对其停止编报。
