VONGFONG is entering the westerlies, and therefore a NE to ENE movement is expected in the remainder of the forecast period.
黃蜂即將進入西風帶,並於餘下時間向東北至東北偏東移動。
Intensity Analysis 強度分析
Current T-number: T2.5/3.0/W0.5/18 HRS
VONGFONG will continue to weaken as a result of cooler sea surface. Extratropical transition is expected in 24 to 36 hours.
現時的 T 號碼: T2.5/3.0/W0.5/18 HRS
隨著黃蜂緯度增加,預料它將會因較低海水溫度而逐漸減弱。在斜壓環境下,黃蜂將於 24 至 36 小時內完成溫帶氣旋轉化。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
黃蜂於未來的 72 小時將不會對香港構成任何影響。

Tropical disturbance 96W south of Japan has intensified quickly into a tropical depression early today (12W) and then tropical storm this morning, and was named VONGFONG by the JMA. At 14 HKT, VONGFONG was centred about 730 km (400 NM) SSW of Tokyo.
VONGFONG is about to enter the westerlies, and therefore a NE to ENE movement is expected in the remainder of the forecast period.
黃蜂將進入西風帶,並於餘下時間向東北至東北偏東移動。
Intensity Analysis 強度分析
Current T-number: T3.0/3.0/INT OBS
Excellent outflow, low vertical wind shear and adequate sea surface temperatures have caused VONGFONG to quickly intensify. It is expected to peak at 55 knots in strength in 12 hours, before weakening as a result of increased shear and cooler sea surface. Extratropical transition is expected in 48 hours.
現時的 T 號碼: T3.0/3.0/INT OBS
良好的輻散通道、溫暖的海水和非常微弱的垂直風切變令黃蜂於過去 24 小時大幅增強。隨著黃蜂緯度增加,預料它將會因較低海水溫度及較高垂直風切變而逐漸減弱。在斜壓環境下,黃蜂將於 48 小時內完成溫帶氣旋轉化。
