Strong winds are still being observed at some locations. It is too far away for VICENTE to directly produce such winds; it is likely that the southeasterly airstream prevailing in the southwestern periphery of the subtropical ridge is also contributing to that. Showers will continue to affect Hong Kong tomorrow although the intensity will drop gradually.
VICENTE made landfall at Chixi, Taishan shortly after 04 HKT today and has weakened rapidly since then. At 14 HKT, VICENTE was centred about 360 km (200 NM) W of Hong Kong. The Standby Signal is currently issued.

VICENTE continued to intensify prior to landfall. The JTWC amended their 20 HKT bulletin to reflect the much better cloud signature than previously observed. At 02 HKT, VICENTE was centred about 100 km (55 NM) SW of Hong Kong Observatory. The Hurricane Signal No. 10 was issued at 00:45 HKT. This is the first such signal issued since September 1999 when Typhoon YORK approached the territory.

[As of 03 HKT 截至上午 3 時]
Local winds have generally reached gale force. SW parts of Hong Kong are currently very close to the eyewall and 10-minute sustained winds at Cheung Chau reached 136 km/h during the past hour, well above the threshold for hurricane force. Wind direction is now changing to the SE as VICENTE makes its closest approach to our SW. Wind speed will gradually weaken after VICENTE makes landfall in the next hour or two. Squally showers will continue to affect the territory today.
People living in low-lying areas should beware of flooding arising from storm surge.
VICENTE has rapidly intensified into a high-end category 2 typhoon. At 00 HKT, VICENTE was centred about 110 km (60 NM) SSW of Hong Kong. The No. 9 Increasing Gale or Storm Signal was issued at 23:20 HKT.

Winds have significantly strengthened after sunset and currently a lot of stations in urban areas are registering gale force winds, while some offshore and high-ground stations are blowing storm force winds or above. Winds will continue to strengthen and VICENTE is expected to be closest to Hong Kong in the next 3 to 4 hours. Winds will then veer to the southeast early today (July 24). There will be frequent squally showers throughout tonight.
People living in low-lying areas should beware of flooding during high-tide at around 02 HKT tonight. Please stay tuned for VICENTE's latest development.
VICENTE is moving NW to NNW and has intensified slightly in the past 6 hours. At 20 HKT, VICENTE was centred about 150 km (80 NM) S of Hong Kong. The No. 8 NE Gale or Storm Signal was issued at 17:40 HKT.

According to the present forecast track, VICENTE may enter Hong Kong's 100-km circle later tonight. Various stations are now registering gale force winds or even stronger, blowing in from the northeast. Wind direction will gradually veer to the southeast tomorrow, and will continue to strengthen as VICENTE edges closer. There will be frequent squally showers throughout tonight. Please complete all necessary precautions and stay tuned for VICENTE's latest development.
VICENTE continued to intensify and has reached typhoon strength. It also moved northwards steadily but slowly in the past 6 hours. At 11 HKT, VICENTE was centred about 270 km (150 NM) SSE of Hong Kong.
VICENTE is the 139th name in the tropical cyclone name list. It was contributed by the United States, and is a Chamorro male name. This name was last used in 2005, the storm associated with which necessitated the Standby Signal in Hong Kong.
VICENTE has started to move north under the combined influence of the subtropical ridge and the equatorial anticyclone. The subtropical ridge is expected to re-extend westwards in the near future, and as VICENTE moves further north, the effect from the equatorial anticyclone will diminish. These factors will put VICENTE back on a westerly course.
Current T-number: T4.0/4.0/D1.0/15 HRS
VICENTE's convections have successfully wrapped into its eastern semicircle and the storm appears to be creating a banding eye. The storm's overall structure has also become more symmetric. VICENTE should continue to intensify in the very warm South China Sea with decent divergence and low shear. It will weaken gradually upon landfall.

As VICENTE takes a northward turn, winds in Hong Kong have backed from the east to northeast. Strong winds are now blowing in some locations, and winds are expected to strengthen in the next 12 hours as VICENTE edges closer and continues to intensify. Wind direction will then veer to the southeast on Tuesday. Squally showers will affect the territory in the next two days. Please carry out precautionary measures as soon as possible and stay tuned for the latest development of the tropical cyclone.
VICENTE has intensified into a severe tropical storm and has essentially stopped moving. At 20 HKT, VICENTE was centred about 370 km (200 NM) SSE of Hong Kong.
VICENTE is the 139th name in the tropical cyclone name list. It was contributed by the United States, and is a Chamorro male name. This name was last used in 2005, the storm associated with which necessitated the Standby Signal in Hong Kong.
The subtropical ridge has retreated following the propagation of a mid-latitude trough in eastern China. Together with the effect of an equatorial anticyclone, VICENTE is lack of a net steering force and is drifting irregularly in the past 12 hours as the storm develops. It is expected that such slow movement will persist in the next 12 hours. After that, the ridge should re-extend to the west and push VICENTE westwards towards western Guangdong.
Current T-number: T3.0/3.0/D0.5/24 HRS
VICENTE's convections have become more symmetric in the past 24 hours, but clouds to the north are relatively thin. The storm is under an environment with high sea temperatures and low to moderate shear, and intensification is expected in the next 48 hours. VICENTE will weaken gradually after making landfall.
現時的 T 號碼: T3.0/3.0/D0.5/24 HRS
韋森特的對流於過去 24 小時變得更為對稱,但其北面雲帶相對薄弱。風暴一帶海溫較高,風切低至中等,預料將於未來 48 小時繼續增強。韋森特將於登陸後逐漸減弱。

Squally showers have started to affect Hong Kong. As VICENTE edges closer tomorrow, easterly to northeasterly winds will strengthen to strong force or above and wind direction will veer to the southeast on Tuesday. VICENTE will affect Hong Kong for a longer period than expected due to its slow movement.
92W was upgraded into tropical depression 09W by the JTWC early today, while the JMA upgraded the system into a tropical storm tonight, naming it VICENTE. At 20 HKT, VICENTE was centred about 460 km (250 NM) SE of Hong Kong. The Standby Signal No. 1 was issued at 15:40 HKT.
VICENTE is the 139th name in the tropical cyclone name list. It was contributed by the United States, and is a Chamorro male name. This name was last used in 2005, the storm associated with which necessitated the Standby Signal in Hong Kong.
Current T-number: T2.5/2.5/D0.5/24 HRS
VICENTE needs time to allow convections to wrap around its eastern semicircle. Due to the high sea temperatures and low to moderate shear in the northern South China Sea, numerical models have been consistently predicting some development.
現時的 T 號碼: T2.5/2.5/D0.5/24 HRS
韋森特需要時間將對流捲至其東半圓。由於南海北部海溫較高,風切處於低至中等水平,數值模式均多報預計韋森特將有一定發展空間。

Intense heat brought thunderstorms and downpour to parts of Hong Kong this evening. The weather will deteriorate tomorrow with winds strengthening from the east to northeast. Wind direction will veer to the southeast later tomorrow to early Monday. Hong Kong will be affected by squally showers in the next two days.
The Observatory has upgraded tropical disturbance 92W east of Luzon into a tropical depression. At 20 HKT, 92W was centred about 420 km (230 NM) NNE of Manila.
92W is situated in the southwestern periphery of a subtropical ridge that extends into southern China. Under its influence, 92W is expected to track WNW into the South China Sea in the next 24 hours. The storm is expected to move in a more equatorward direction when it reaches higher latitude.
Current T-number: T2.0/2.0/INT OBS
Convections appear to be gradually wrapping into 92W's centre, but the system still needs some time for development. Gradual intensification is expected as the storm will track through warm seas with acceptable wind shear.
現時的 T 號碼: T2.0/2.0/INT OBS
對流似乎開始逐漸捲入 92W 的中心,但系統仍需時間整合。92W 將橫過較暖的海域,垂直風切變水平可以接受,預料將逐漸增強。
