| Overview 總覽 |
|
JTWC upgraded a disturbance east of the Philippine Sea into a tropical depression tonight and it was given a temporary number 14W. At 12 UTC, 14W was centred 1710 km (930 NM) E of Manila.
聯合颱風警報中心於 12 UTC 把在菲律賓海東部的一個熱帶擾動升格為一熱帶低氣壓，並給予臨時編號 14W。於 12 UTC，14W 集結於馬尼拉以東約 1710 公里 (930 海里)。

| Movement Analysis 路徑分析 |
Due to the southern extension of the broad subtropical ridge, 14W is currenly moving northwards with a small western component. It is expected that when 14W continues to move northward, it will be gradually steered by the subtropical ridge anchored SE of Japan and thus will turn into a more westerly direction.
受到副熱帶高壓脊南部的延伸部分之影響，14W 於過去 24 小時向北移動。預料隨著 14W 北移，它將逐漸受該副熱帶高壓脊影響 (在其西南部) 而轉為向偏西方向移動。 |
| Intensity Analysis 強度分析 |
14W had a T-number of 1.5 at 08 UTC that translates to maximum wind speed of 25 knots (tropical depression). It is expected that 14W will gradually intensify as it encounters warm sea surface temperatures and low vertical wind shear.
在 08 UTC，14W 的T號碼為1.5，即 25 節的風速 (熱帶低氣壓)。14W 將於溫暖的海水及逐漸移至較弱垂直風切變的環境下逐步增強。 |
| Effects on Hong Kong 對香港的影響 |
No threat to Hong Kong is expected within the next 72 hours.
14W 於未來的72小時將不會對香港構成任何影響。 |
