22W intensified into a tropical storm briefly last night but weakened again today. It has just made landfall at Vietnam. At 20 HKT, 22W was centred about 300 km (160 NM) S of Hanoi.
Disturbance 94W drifted westward in the past few days and managed to intensity into a tropical depression (22W) before touching Vietnam. At 20 HKT, 22W was centred about 270 km (140 NM) SE of Hanoi.
A subtropical ridge is situated north of the system, which is expected to drive 22W west to west-northwest into Vietnam in the next 36 hours.
預料在 22W 北面的副熱帶高壓脊將於未來 36 小時帶領 22W 向西或西北偏西移動,趨向越南。
Intensity Analysis 強度分析
Current T-number: T2.0/2.0/INT OBS
Slight intensification before landfall is still possible under favourable sea temperatures. Dissipation is expected before t+36.
現時的 T 號碼: T2.0/2.0/INT OBS 22W 於登陸前將繼續受惠於頗高海水溫度而有望增強為熱帶風暴。該系統將於 36 小時內在內陸消散。
