预报：高拴柱 何萍 签发：聂高臻 2021年 08月 21日 10时

“奥麦斯”继续向西北方向移动

一、“奥麦斯”位于西北太平洋洋面上

今年第12号台风“奥麦斯”（热带风暴级）的中心今天（8月21日）上午8点钟位于冲绳那霸偏南方向约560公里的西北太平洋洋面上，就是北纬21.2度，东经128.1度，中心附近最大风力有8级（18米/秒），中心最低气压为1002百帕，七级风圈半径为120-200公里。

二、“奥麦斯”逐渐向冲绳群岛南部海域靠近

预计，“奥麦斯”将以每小时20-25公里的速度向西北方向移动，强度将有所加强，并向冲绳群岛南部海域靠近，22日上午移入东海东南部海面，之后将由偏北转东北方向移动，23日起强度逐渐减弱，趋向朝鲜半岛南部一带沿海。
