BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
BOPHA will start to lose latitude as the low-level circulation centre is carried away by the northeast monsoon.
寶霞的低層環流中心將因東北季候風的影響而南移。

BOPHA intensified into a category 3 typhoon last night but is now weakening gradually, edging closer to northwestern Philippines. At 14 HKT, BOPHA was centred about 670 km (360 NM) SE of Hong Kong.
BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
BOPHA is moving NE to ENE along the northwestern periphery of the subtropical ridge. As the northeast monsoon weakens the system, it will then be subject to low-level steering and is expected to move S turning to SW. The storm will linger in close proximity to Luzon in the next day or two as competing forces act on the system.
Current T-number: T4.0/4.5/W1.0/24 HRS
BOPHA's well-defined eye did not last long. It is now in a region of very high shear, and the result is that the high-level circulation will continue to move NE to ENE while the low-level circulation mass will be pushed southwards by the northeast monsoon. In other words the storm's vertical structure will be torn apart, leading to rapid weakening.
現時的 T 號碼:T4.0/4.5/W1.0/24 HRS
寶霞清晰的風眼形成後不久已經消失。現時寶霞所處位置垂直風切變非常高，結果將令其高層結構繼續向東北至東北偏東移，而低層環流則受東北季候風引導向南移。由於風暴垂直結構嚴重受損，其強度將急速降低。

of TC Signals from HKO 香港天文台發出 / 取消熱帶氣旋警告信號的機率
As BOPHA weakens and is showing no signs of approaching Hong Kong, the chance of issuing TC signals is extremely low.
BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
BOPHA will move N to NNE along the western periphery of the subtropical ridge. The upcoming surge of northeast monsoon will weaken the system, and subject it to low-level steering that will bring the storm southwards. The storm will move slowly while it interacts with the monsoon within the pressure col.
Current T-number: T5.0/5.0/D1.5/24 HRS
Benefiting from improved divergence from the trough, BOPHA has intensified in the past 6 hours and its eye becomes well-defined again. The storm should continue to intensify in the next 6 to 12 hours, but such strength is short-lived as shear will increase dramatically when the northeast monsoon arrives, literally tearing the storm apart and rapid weakening will follow.
BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
BOPHA is expected to move NW turning gradually to N along the western periphery of the subtropical ridge. The upcoming surge of northeast monsoon will weaken the system, and should eventually carry BOPHA towards the SW. The storm will remain quasi-stationary while it interacts with the monsoon within the pressure col.
Current T-number: T3.5/4.0/W0.5/24 HRS
BOPHA should maintain its current strength or intensify slightly before interacting with the northeast monsoon, and gradual weakening thereafter. The storm is expected to reduce to below tropical storm strength by t+120.
現時的 T 號碼: T3.5/4.0/W0.5/24 HRS
寶霞將於受東北季候風影響前維持強度或稍為增強，其後逐漸減弱，預料於五天後減弱至熱帶風暴以下強度。

BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
BOPHA is expected to move WNW to NW into the pressure col between the ridges. The storm will decelerate significantly in the next 72 hours and then remain quasi-stationary. Direction of motion beyond t+72 remains highly variable, though there is high confidence that interaction with the strong northeast monsoon will eventually erode the system and bring the remnants southwards.
Current T-number: T4.0/4.5/W1.0/24 HRS
As BOPHA enters South China Sea, the storm may regain some power as sea temperatures and shear remain favourable. However the upcoming surge of northeast monsoon is too strong for BOPHA to withstand; as it stagnates in the sea it will gradually be eroded by the cold, dry air mass.
現時的 T 號碼: T4.0/4.5/W1.0/24 HRS
由於南海中部海溫和垂直風切變皆有利熱帶氣旋發展，預料寶霞將能稍為增強。但緊隨的東北季候風強度不弱，寶霞將會被該乾冷氣團逐漸侵蝕。

BOPHA intensified into a category 5 super typhoon last night and made landfall at Mindanao early today. It has since then weakened into a category 2 typhoon. At 14 HKT, BOPHA was centred about 750 km (400 NM) SSE of Manila.
BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
A weakness in the subtropical ridge is about to deepen and break the ridge. BOPHA will then travel NW along the southwestern periphery of the eastern ridge. As the ridge continues to retreat, BOPHA is expected to stagnate in central South China Sea.
Current T-number: N/A
BOPHA intensified into a category 5 super typhoon last night, but Mindanao terrain is causing the storm to weaken rapidly. As BOPHA reaches ocean again, it is expected to maintain current intensity or even intensify slightly. However, a surge of northeast monsoon is expected to propagate southwards in the next few days and such interaction will cause BOPHA to resume its weakening trend starting from t+48.
現時的 T 號碼: 不適用
寶霞昨晚增強為五級超級颱風，但棉蘭老島地形令其急速減弱。隨著寶霞再次進入洋面，預料它將維持強度甚或稍為增強。可是，一股東北季候風將於未來數天向南擴展，寶霞將於兩天後受冷空氣影響而再度減弱。

BOPHA weakened last night but its eye re-emerged in satellite images and is now intensifying slightly. The storm should maintain intensity while it approaches the Philippines, and will weaken as it travels through landmass. A surge of northeast monsoon is expected to propagate southwards in the middle of the week and such interaction will cause BOPHA to weaken significantly towards the end of the forecast period.

BOPHA's central dense overcast achieved a very low cloud top temperature last night and the storm briefly reached super typhoon intensity (130 knots) this morning, but its eye has shrunk since then. The storm is expected to maintain its current intensity or weaken slightly as there is very little room for further intensification. More rapid weakening is expected as the storm passes through the Philippines and reaches higher latitude.

BOPHA has rapidly intensified into a category 3 typhoon, and has started to pick up a WNW track. At 14 HKT, BOPHA was centred about 780 km (420 NM) ESE of Palau.
BOPHA is the fifteenth name in the tropical cyclone name list. It was contributed by Cambodia, meaning flower or a little girl. This name was used in 2000 and 2006, with the latter occurrence necessitating the #1 Standby Signal.
There's a slight southward extension of the ridge to the east of BOPHA. The storm is expected to move WNW in the next 120 hours. Numerical models start to diverge towards the end of the forecast period due to the uncertainty in the strength of the arriving trough.
Current T-number: T5.5/5.5/D1.5/24 HRS
BOPHA developed an clear eye earlier today but its size has shrunk in the past 6 hours. Due to excellent divergence and high sea temperatures, intensification is expected in the next 36 hours. The storm may weaken slightly afterwards as ocean heat content drops, but significant weakening is not expected until the storm makes landfall at the Philippines.
現時的 T 號碼: T5.5/5.5/D1.5/24 HRS
寶霞今天發展出明顯風眼，但於過去 6 小時縮小。由於寶霞一帶幅散極佳且海溫較高，風暴仍能於未來 36 小時增強，隨後由於海洋熱含量降低而略為減弱，但預料明顯減弱只會於風暴登陸菲律賓後才開始。

Current T-number: T2.5/2.5/D0.5/24 HRS
BOPHA is expected to intensify gradually in warm seas (29 to 30 degrees) with very low vertical wind shear, and may attain typhoon intensity by t+48 to t+72.
A tropical disturbance in northwest Pacific intensified into tropical depression 26W today. At 14 HKT, 26W was centred about 610 km (330 NM) ESE of Chuuk.
A broad subtropical ridge is covering much of the ocean north of 26W. The storm is thus expected to move WNW in the next 72 hours. As the storm moves to a higher latitude, its influence from the subtropical ridge increases and is expected to move faster.
Current T-number: T2.0/2.0/INT OBS
26W is expected to intensify gradually in warm seas (29 to 30 degrees) with very low vertical wind shear, and may attain typhoon intensity by t+72.
