VONGFONG is the 63rd name in the tropical cyclone name list. It was contributed by Macau, meaning wasp. This name was used in 2002 and 2008, with the former necessitating a #1 Standby Signal.
VONGFONG is approaching southwestern Japan. At 8 am, VONGFONG was centred about 40 km (20 NM) SW of Kagoshima.

VONGFONG's convections are apparently sheared away due to strong vertical wind shear. The cyclone is now undergoing extratropical transition, and should become fully extratropical in 24 hours' time.
受強烈垂直風切變影響，黃蜂的對流明顯被切離。風暴正進行溫帶氣旋轉化，預料於 24 小時內完成。

VONGFONG is the 63rd name in the tropical cyclone name list. It was contributed by Macau, meaning wasp. This name was used in 2002 and 2008, with the former necessitating a #1 Standby Signal.
VONGFONG is expected to move north along the western periphery of the subtropical ridge. The ridge will reorient itself under the effect of a passing trough, and this should cause VONGFONG to recurve to the northeast. VONGFONG will accelerate along the strong westerlies.
VONGFONG's core has become loose in the past 24 hours. The storm is expected to weaken as sea temperatures drop and vertical wind shear becomes stronger. Extratropical transition will be complete by t+72.
VONGFONG has weakened into a category 3 typhoon and is now approaching Ryukyu Islands. At 8 am, VONGFONG was centred about 240 km (130 NM) SSE of Okinawa.

A weak ridge builds to the north of VONGFONG, and is expected to cause VONGFONG to move NNW briefly. As that ridge passes, VONGFONG will recurve northeast along the northwestern periphery of the subtropical ridge. It will accelerate rapidly due to strong steering along the westerlies.
VONGFONG is expected to weaken as it moves north, when sea temperatures drop and vertical wind shear becomes stronger. Extratropical transition will be complete by t+96.
黃蜂北上時將因海溫漸漸轉冷及垂直風切變增強而減弱，轉向後開始轉化為溫帶氣旋，並於四天內完成。

VONGFONG is the 63rd name in the tropical cyclone name list. It was contributed by Macau, meaning wasp. This name was used in 2002 and 2008, with the former necessitating a #1 Standby Signal.
VONGFONG will move north along the western edge of the subtropical ridge. The ridge may build back temporarily near t+24, leading to a slight deflection to the NNW. This is followed by another wave of weakening of the subtropical ridge, allowing VONGFONG to recurve to the northeast.
VONGFONG's eyewall continued to shrink and the storm is showing signs of entering an eyewall replacement cycle. VONGFONG will weaken gradually as it enters cooler seas, and extratropical transition is expected before t+120.
VONGFONG has weakened slightly, but remains as a category 5 super typhoon. The storm is also turning poleward. At 8 am, VONGFONG was centred about 820 km (450 NM) SSE of Okinawa.

VONGFONG will turn north, moving along the western edge of the subtropical ridge. The ridge may build back temporarily near t+48, leading to a slight deflection to the west. This is followed by another wave of weakening of the subtropical ridge, allowing VONGFONG to recurve to the northeast.
VONGFONG's eyewall cloud-top temperatures continued to rise, and its eyewall is visibly thinner than yesterday. VONGFONG should have reached the maximum tolerable intensity of that area, and is expected to weaken gradually as it enters cooler seas.

The subtropical ridge has retreated; VONGFONG is gradually slowing down and is expected to turn north in the next 24 hours. The storm should move in a generally northerly direction along the western edge of the weakened ridge, but the ridge may build back temporarily near t+72, leading to a slight deflection to the west.

VONGFONG developed a thick, symmetric eyewall yesterday and a clear eye is embedded within it. The storm's eyewall cloud-top temperatures reached -80 degrees, indicating violent convective activities. VONGFONG should have reached the maximum tolerable intensity of that area, and is expected to weaken gradually. The rate of weakening will increase later on as the storm will cross a pool of cool waters resulting from PHANFONE's recent passage.
VONGFONG is gradually decelerating. At 8 am, VONGFONG was centred about 1370 km (740 NM) SE of Okinawa.

The subtropical ridge north of VONGFONG is retreating. As the ridge breaks down near t+24, VONGFONG will come to a halt and will start moving northward. Thereafter the storm should move in a generally northerly direction along the western edge of the weakened ridge, but some models are calling for a track slightly west of north due to the ridge rebuilding temporarily.
VONGFONG struggled to develop last night, but its eye is consolidating quickly in the past 6 hours. The storm will intensify in warm seas with low vertical wind shear, reaching peak strength near its northward turn. While VONGFONG travels north, it is expected to weaken sharply as it will cross a pool of cool waters resulting from PHANFONE's recent passage.
VONGFONG is moving WNW rapidly. At 8 am, VONGFONG was centred about 240 km (130 NM) NW of Guam.

A subtropical ridge is situated north of VONGFONG; the storm is expected to move WNW in the next 48 hours. The ridge is expected to weaken sharply between t+48 and t+72, leading to an abrupt deceleration and poleward turn.
VONGFONG's central dense overcast is still unstable, and convections in the northern semicircle have diminished as divergence weakens. Nevertheless, the storm should be able to intensify in warm seas with low to moderate vertical wind shear, at least until its poleward turn.
VONGFONG has intensified into a typhoon. At 8 am, VONGFONG was centred about 560 km (310 NM) E of Guam.
