SANBA is the seventh name in the tropical cyclone name list. It was contributed by Macau, and is the Chinese colloquial name of the Ruins of St. Paul's. This name replaces Chanchu which was used in 2000 and 2006, with the last appearance causing major damage to the Philippines, Vietnam and China. That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
SANBA is approaching South Korea. At 08 HKT, SANBA was centred about 400 km (210 NM) SSE of Seoul.
三巴正逼近南韓。在上午 8 時,三巴集結在首爾東南偏南約 400 公里 (210 海里)。

That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
SANBA is situated in the WSW periphery of the subtropical ridge, and is expected to move NNW turning to N as it crosses the ridge axis. Due to the great expanse of the subtropical ridge, a gradual recurvature is projected.
Current T-number: T5.5/6.0/W1.5/24 HRS
SANBA's eye becomes unstable and the central dense overcast has shrunk in size. As SANBA enters a region with higher shear (and decreasing sea temperatures later on), it is expected to weaken prior to landfall at South Korea. Extratropical transition will occur at around t+72 to t+96.
現時的 T 號碼: T5.5/6.0/W1.5/24 HRS
三巴的風眼變得不穩定,中心密集雲區範圍收窄。隨著三巴進入較高垂直風切變 (稍後進入較低海溫) 的區域,三巴將於登陸南韓前減弱。預料三巴將於三至四天後轉化為溫帶氣旋。

SANBA continued to intensify rapidly and becomes the first category 5 super typhoon this year today. At 08 HKT, SANBA was centred about 940 km (510 NM) SSE of Okinawa.
SANBA is the seventh name in the tropical cyclone name list. It was contributed by Macau, and is the Chinese colloquial name of the Ruins of St. Paul's. This name replaces Chanchu which was used in 2000 and 2006, with the last appearance causing major damage to the Philippines, Vietnam and China. That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
There are two centres in the subtropical ridge east of SANBA, one to the east of Japan and the other west of Guam. Influence from the lower segment resulted in SANBA's poleward movement in the past 24 hours. SANBA is expected to move NNW turning to N as it moves north and starts to be affected by the upper centre.
Current T-number: T7.0/7.5/D2.0/24 HRS
The explosive intensification resulted in an extremely thick layer of clouds in SANBA's central dense overcast, with cloud top temperatures reaching -80 degrees Celsius. The eye is well-defined and devoid of clouds. However cloud top temperatures appear to have risen in the past 6 hours, indicating possible weakening trend. SANBA has reached the maximum tolerable intensity and is expected to weaken gradually as it moves north. Weakening will become more rapid later on when SANBA enters a region of lower sea temperatures.
現時的 T 號碼: T7.0/7.5/D2.0/24 HRS
爆發增強令三巴的中心密集雲區非常深厚,雲頂溫度達攝氏零下 80 度,而風眼則有晴空區,但雲頂溫度於過去 6 小時有所上升,風暴似乎呈減弱之勢。三巴已達到該區大氣環境可承受的強度上限,預料將於北移期間逐漸減弱,減弱速度於後期海溫降低時加快。

This name replaces Chanchu which was used in 2000 and 2006, with the last appearance causing major damage to the Philippines, Vietnam and China. That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
The ridge near Taiwan is diminishing, and SANBA is expected to move NNW turning to N in the next 72 hours along the western periphery of a NNW-SSE oriented subtropical ridge.
Current T-number: T5.0/5.0/D1.5/24 HRS
SANBA has developed a round eye within its central dense overcast, with apparent evidence that rapid intensification is underway. The system is in an area with good outflow, weak vertical wind shear and high sea temperatures. Rapid intensification is expected within the next 12 to 24 hours, and after that the storm will intensify at a slower pace.
現時的 T 號碼: T5.0/5.0/D1.5/24 HRS
三巴的中心密集雲區內發展出一圓渾的風眼,有跡象顯示風暴正急速增強。三巴一帶輻散良好,垂直風切變微弱而海溫較高,預料將於未來 12 至 24 小時繼續急速增強,隨後增強速度將放緩。

This name replaces Chanchu which was used in 2000 and 2006, with the last appearance causing major damage to the Philippines, Vietnam and China. That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
SANBA is travelling more westward than expected as a result of the influence from the ridge near Taiwan. That ridge will gradually weaken and the subtropical ridge east of the system, still N-S oriented, will drive SANBA towards the NNW.
Current T-number: T3.5/3.5/D1.0/24 HRS
SANBA's convections are wrapping nicely around the centre. The storm is expected to strengthen at about climatological rate as it tracks through warm ocean in an area with low shear.

Tropical disturbance 98W east of the Philippines has gradually intensified into tropical storm 17W and was named SANBA. At 08 HKT, SANBA was centred about 420 km (230 NM) W of Yap.
SANBA is the seventh name in the tropical cyclone name list. It was contributed by Macau, and is the Chinese colloquial name of the Ruins of St. Paul's. This name replaces Chanchu which was used in 2000 and 2006, with the last appearance causing major damage to the Philippines, Vietnam and China. That appearance also prompted the Observatory to issue the #3 Strong Wind Signal.
The subtropical ridge is currently N-S oriented and situated to the northeast of SANBA. Another ridge is seen near Taiwan, with a huge weakness in between. SANBA is expected to track NNW along the subtropical ridge through the weakness in the forecast period.
Current T-number: T2.5/2.5/INT OBS
SANBA is in an area of low shear and high sea temperatures, and has been intensifying in the past 12 hours. The storm is expected to strengthen at about climatological rate as it tracks across the Philippine Sea.
