SANVU developed a well-defined eye earlier today, but has since become more ragged. As seas start to cool and shear rises, SANVU will weaken progressively. Extratropical transition is expected in around three days' time.

珊瑚的風眼今天較早時候非常清晰，但現在形狀變得不規則。隨著海溫降低而垂直風切變提升，珊瑚將開始減弱。珊瑚將於約三天後轉化為溫帶氣旋。

SANVU is now constructing a banding eye. The storm's intensity is expected to peak at around t+12, after which cooler seas and higher wind shear will cause SANVU to weaken. Extratropical transition will take place at around t+72.

珊瑚正在建立雲捲風眼。預料珊瑚的強度將於 12 小時後到達顛峰，隨後因較低海溫和逐漸提升的垂直風切變而減弱。珊瑚將於約三天後轉化為溫帶氣旋。

珊瑚正以約氣候平均值速度增強。在良好海溫和偏低垂直風切變環境下，預料珊瑚將於明日增強為颱風。隨著海溫因緯度增加而下降，珊瑚將於 36 小時後開始減弱，並於約四天後轉化為溫帶氣旋。

03W neared Guam last night and has intensified into a tropical storm. It was named SANVU by the JMA. At 20 HKT, SANVU was centred about 290 km (160 NM) WNW of Guam.
SANVU is the 133rd name in the tropical cyclone name list. It was contributed by Macau, meaning coral. This name was last used in 2005, the storm associated with which necessitated the Standby Signal in Hong Kong.
The southern extension of the subtropical ridge has caused SANVU to track NNW briefly last night, and it has now resumed a WNW/NW movement. The ridge is steadily retreating and SANVU will recurve at its western periphery.
Current T-number: T3.0/3.0/D1.0/24 HRS
SANVU's cloud bands are tightening, and ambient vertical wind shear has dropped. The storm is expected to travel across warm seas (around 29 degrees) and outflow channels will be enhanced by the arriving trough that weakens the ridge. These factor will cause SANVU to strengthen steadily up to t+48. After that, SANVU will weaken as seas become cooler, and extratropical transition should complete by t+120.
03W is currently moving WNW along the southwestern periphery of the subtropical ridge anchored to its northeast. Numerical models are consistently predicting the ridge to recede in the next few days, allowing 03W to recurve along its western periphery.
Current T-number: T2.0/2.0/INT OBS
03W is in warm seas (around 29 degrees) with moderate shear and decent outflow channels. Gradual intensification is expected until at least t+72.
