KOPPU has weakened into a tropical storm. At 20 HKT, KOPPU was centred about 450 km (240 NM) W of Hong Kong. All tropical cyclone signals were cancelled at 15:40 HKT.
KOPPU is the 89th name in the tropical cyclone name list. This name was contributed by Japan, meaning the constellation Crater (Cup). This name was last used in 2003.
KOPPU made landfall at Taishan this morning and weakened afterwards. At 11 HKT, KOPPU was centred about 270 km (150 NM) W of Hong Kong. The #3 Strong Wind Signal was issued at 10:15 HKT.

KOPPU turned WNW after jogging north for a couple of hours. At 00 HKT, KOPPU was centred about 150 km (80 NM) SSW of Hong Kong. The Observatory issued the #8 SE Gale or Storm Signal at 00:35 HKT, replacing the NE Signal.
KOPPU is the 89th name in the tropical cyclone name list. This name was contributed by Japan, meaning the constellation Crater (Cup). This name was last used in 2003.
The part of the subtropical ridge north of KOPPU has weakened while the eastern part has strengthened. This is expected to provide poleward component to KOPPU's future track and thus a WNW to NW movement should be observed. KOPPU is expected to make landfall in Guangdong early today.
Current T-number: T4.5/4.5/D1.5/24 HRS
KOPPU's eye is discernible in IR imagery. It is expected to remain as a typhoon until landfall, after which it will weaken rapidly.

Gale force winds are blowing in the territory from the east, while storm force winds are recorded on high grounds and in offshore waters. Wind direction will change from E to SE very soon, the strength of which will remain very strong. Heavy squally showers will continue to affect the territory, and storm surge is likely to cause flooding in low-lying areas.
KOPPU took a more northerly track in the past 6 hours. At 20 HKT, KOPPU was centred about 160 km (85 NM) S of Hong Kong. The Observatory issued the #8 NE Gale or Storm Signal at 17:55 HKT.

The part of the subtropical ridge north of KOPPU has weakened while the eastern part has strengthened. This is expected to provide poleward component to KOPPU's future track and thus a WNW to NW movement should be observed. KOPPU is expected to make landfall in Guangdong tomorrow.

Gale force winds are blowing in the territory from the northeast, while storm force winds are recorded on high grounds and in offshore waters. Winds are expected to strengthen further tonight, with wind direction gradually changing to SE early tomorrow. Heavy squally showers will continue to affect the territory, and storm surge is likely to cause flooding in low-lying areas.
16W intensified quickly last night and has developed a banding eye, and in 1-minute average it is upgraded to typhoon status. It was named KOPPU by the JMA earlier. At 13 HKT, KOPPU was centred about 270 km (140 NM) SSE of Hong Kong. The Observatory issued the Strong Wind Signal at 11:15 HKT, and will consider the need for higher signals near dusk.
KOPPU is the 89th name in the tropical cyclone name list. This name was contributed by Japan, meaning the constellation Crater (Cup). This name was last used in 2003.
The part of the subtropical ridge north of KOPPU has weakened slightly while the eastern part has strengthened. This is expected to provide poleward component to KOPPU's future track and thus a WNW movement should be observed. KOPPU is expected to make landfall in western Guangdong tomorrow.
Current T-number: T4.0/4.0/D1.5/18 HRS
KOPPU developed quickly last night in good ambient environments, revealing a banding eye clearly discernible in visible imagery in the past few hours. It is expected to strengthen further in the next 6 to 12 hours, and will weaken rapidly once it reaches land.

Effects on Hong Kong 對香港的影響
KOPPU's outer rain bands have started to affected the territory. As KOPPU continues to intensify and edge closer, winds will strengthen significantly tonight, possibly with gale force winds. Wind direction will be initially northeast, changing gradually to southeast early tomorrow.
16W moves into the South China Sea as it tries to consolidate itself. At 20 HKT, 16W was centred about 510 km (270 NM) SE of Hong Kong. The Observatory issued the Standby Signal at 20:35 HKT.
16W is expected to travel WNW in the southwestern periphery of the subtropical ridge towards Guangdong. Poleward component may increase later on due to the possible re-orientation of the subtropical ridge to NW-SE direction.
Current T-number: T2.5/2.5/D0.5/24 HRS
16W should be able to intensify gradually in the warm South China Sea with low shear. Rapid weakening is expected after landfall near t+36.
Convective clouds brought severe thunderstorms to the region earlier tonight. As 16W nears, winds are expected to strengthen tomorrow from the northeast with occasional squally showers.
As 16W consolidates its centre shifts to west of Luzon. 16W is expected to travel WNW in the southwestern periphery of the subtropical ridge towards Guangdong. Westward component may be more prominent as it reaches 20°N due to the orientation of the ridge.
Current T-number: T2.5/2.5/D0.5/18 HRS
After leaving Luzon, 16W should be able to intensify. However the high-level convergence north of the system may impede outflow which could potentially slow down the rate of intensification. Rapid weakening is expected after landfall near t+48.
Hazy and very hot weather will be observed for the rest of today. Winds are expected to strengthen tomorrow from the northeast with occasional squally showers.
酷熱和有煙霞的天氣將於今天餘下時間持續。香港將吹東北風，風勢於明日稍後增強，間中伴有狂風驟雨。

Disturbance 91W in the Philippine Sea intensified into a tropical depression this afternoon. At 20 HKT, 91W was centred about 440 km (240 NM) NE of Manila.
91W is expected to travel WNW in the southwestern periphery of the subtropical ridge. Westward component may be more prominent as 91W reaches 20°N due to the orientation of the ridge.
Current T-number: T2.0/2.0/INT OBS
Shear is low near Luzon Strait, and both (low-level) convergence and (upper-level) divergence are building up. 91W is expected to intensify at about climatological rate as it travels in the South China Sea. Initial rate of intensification could be lower due to the interaction with northern Luzon.
According to the present forecast track, 91W might come within 200 km of the territory on Tuesday. Winds are expected to strengthen from the east/northeast early next week.
