MITAG has been moving slowly towards the northwest today. At 14 HKT, MITAG was centred about 530 km (290 NM) E of Manila.
米娜於過去 24 小時向西北緩慢移動。在 14 HKT,米娜集結在馬尼拉之東約 530 公里 (290 海里)。

Movement Analysis 路徑分析 |
MITAG will travel WNW to NW in the next 48 hours along the southwestern periphery of the retreating subtropical ridge. The forecast for extended period calls for a recurving scenario supported by most numerical models along the western periphery of the ridge.
預料米娜於未來 48 小時將沿副熱帶高壓脊之西南部向西北偏西至西北移動。其後,隨著副熱帶高壓脊的東退,米娜將沿它的西部轉向北至東北移動。 |
Intensity Analysis 強度分析 |
Current T-number: T4.5/4.5/S0.0/24 HRS
Due to good ambient environments but reduced heat content as MITAG has remained quasi-stationary for about two days, MITAG should be able to maintain strength before making landfall. After that, the combined effect of increased vertical wind shear in the South China Sea and the lack of moisture in the terrain of Luzon will cause MITAG to weaken. After recurvature, MITAG should transit into an extratropical cyclone.
現時的 T 號碼: T4.5/4.5/S0.0/24 HRS
米娜現正處於良好的大氣環境之中。可是由於米娜已經徘徊了兩天,海水的熱量逐漸減少,預料米娜將在登陸前維持強度。當米娜橫過菲律賓,它將會受水氣的缺乏及高垂直風切變影響而顯著地減弱。米娜將於轉向後轉化為溫帶氣旋。 |
Effects on Hong Kong 對香港的影響 |
Combined with the NE monsoon, strong winds may set in three days later.
受到米娜和東北季候風的共同影響,香港鄰近地區可能會在三天後吹強風。 |
