Naming 氣旋命名
WIPHA is the 40th name in the tropical cyclone name list. It was contributed by Thailand, and is a woman's name. This name was used in 2001 (as VIPA) and 2007.

The subtropical ridge has retreated and WIPHA is expected to accelerate NNE/NE with a chance of impacting Tokyo tomorrow.
副熱帶高壓脊東退，預料韋帕將加速向東北偏北或東北移動，有機會於明天掠過東京一帶。

Current T-number: T4.5/5.0/W1.0/24 HRS
WIPHA has weakened in the past 24 hours. Due to low sea temperatures (below 26 degrees) WIPHA will continue to weaken. Extratropical transition is expected by t+36.
WIPHA briefly intensified to a category 4 typhoon, but has weakened back to category 3. At 8 am, WIPHA was centred about 680 km (370 NM) WSW of Iwo Jima.
WIPHA is the 40th name in the tropical cyclone name list. It was contributed by Thailand, and is a woman's name. This name was used in 2001 (as VIPA) and 2007.
A mid-latitude trough will erode the subtropical ridge and create a weakness. WIPHA is expected to move NNW and cross the ridge axis in the next 24 hours. It will later recurve and move NNE at increasing speed.
Current T-number: T5.5/6.0/D0.5/24 HRS; W0.5/06 HRS
WIPHA has developed a well-defined eye, but the eyewall is rather thin. As sea temperature drops, WIPHA is expected to weaken gradually and extratropical transition should be complete by t+72.
現時的 T 號碼: T5.5/6.0/D0.5/24 HRS; W0.5/06 HRS
韋帕發展出一清晰風眼，但眼牆較薄。隨著海溫下降，預料韋帕將逐漸減弱，並於三天內轉化為溫帶氣旋。

WIPHA is the 40th name in the tropical cyclone name list. It was contributed by Thailand, and is a woman's name. This name was used in 2001 (as VIPA) and 2007.
A mid-latitude trough will erode the subtropical ridge and create a weakness. WIPHA is expected to move NW along the southwestern periphery of the ridge, track through the weakness and recurve. It will move rapidly once it turns NE.
Current T-number: T5.0/5.0/D1.5/24 HRS
WIPHA has expanded in size and symmetric convections are spinning nicely around its centre. WIPHA will intensify in warm seas with good divergence, and is expected to become a significant typhoon tomorrow. WIPHA will then weaken as sea temperature drops, and extratropical transition should be complete by t+96.
現時的 T 號碼: T5.0/5.0/D1.5/24 HRS
韋帕的對流擴大，而對稱的螺旋雲帶圍繞中心轉動。在溫暖的海洋及良好輻散的環境下，韋帕將逐漸增強，於明天成為一較強颱風。其後海水溫度降低，韋帕將開始減弱，並將於四天內轉化為溫帶氣旋。

WIPHA's convective banding appears tighter than yesterday. WIPHA will intensify in warm seas with good divergence, and is expected to become a significant typhoon in 2 to 3 days' time. Extratropical transition should be complete by t+120.

韋帕的對流比昨天更為緊密。在溫暖的海洋及良好輻散的環境下，韋帕將逐漸增強，於兩至三天後成為一較強颱風。韋帕將於五天內轉化為溫帶氣旋。
