NOUL will move WNW along the southwestern periphery of the subtropical ridge in the next 24 hours. A passing trough will cause the ridge to retreat, allowing NOUL to recurve around its periphery. It will quickly become embedded in the westerlies, leading to rapid acceleration shortly after recurvature.

紅霞將於未來 24 小時沿副熱帶高壓脊西南部向西北偏西移動。一道西風槽將令副高東退，紅霞將繞其邊沿轉向。轉向後不久紅霞即嵌入西風帶中，因此會急速加速。

Current T-number 現時的 T 號碼: T5.0/5.0/S0.0/24 HRS

由於紅霞附近的流場非常微弱，紅霞將繼續緩慢移動。隨著副熱帶高壓脊增強，紅霞將於明日開始加速，並沿該脊周邊移動，而路徑將逐漸轉北。數值預報模式最近的預測開始較為一致。

Current T-number 現時的 T 號碼: T3.5/3.5/D1.0/24 HRS
