A tropical disturbance NNW of Guam developed into a tropical depression and was denoted by 22W by JTWC. At 20 HKT, 22W was centred about 450 km (250 NM) S of Iwo Jima.
一個在關島西北偏北的擾動今晚增強為熱帶低氣壓，並被給予臨時編號 22W。在 20 HKT，22W 集結在硫磺島之南約 450 公里 (250 海里)。

| Movement Analysis 路徑分析 |
22W will traverse the weakness between the two ridges, followed by a NE track along the NW periphery of the subtropical ridge.
22W 將橫越兩個高壓之間的弱點，並於稍後時間沿副熱帶高壓脊之西北部向東北移動。 |
| Intensity Analysis 強度分析 |
Current T-number: T2.0/2.0/INT OBS
Due to the approaching high shear, 22W is not expected to strengthen by much before its extratropical transition near t+48 to t+72.
現時的 T 號碼: T2.0/2.0/INT OBS
受到較強垂直風切變之影響，預料 22W 在轉化為溫帶氣旋前不會大幅增強。 |
| Effects on Hong Kong 對香港的影響 |
No threat to Hong Kong is expected within the next 72 hours.
22W 於未來的72小時將不會對香港構成任何影響。 |
