Overview 總覽

VICENTE is now crossing Guangxi Province. At 20 HKT, VICENTE was centred about 510 km (270 NM) W of Hong Kong. The Standby Signal is still in force.

韋森特正橫過廣西省。在下午 8 時,韋森特集結在香港以西約 510 公里 (270 海里)。一號戒備信號仍然生效。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

The subtropical ridge has extended and VICENTE will move W along the southern periphery of its western extension.

副熱帶高壓脊已西伸,預料韋森特將依其西部延伸南沿向西移動。

Intensity Analysis 強度分析

Current T-number: N/A
VICENTE's spiraling bands are gradually getting thinner. The storm is expected to weaken into a tropical depression or even dissipate by t+24.

現時的 T 號碼: 不適用
韋森特的螺旋雲帶開始變薄,預料韋森特將於 24 小時內減弱至熱帶低氣壓甚至消散。

Effects on Hong Kong 對香港的影響

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.

香港部分地區仍然吹強風。韋森特已距離香港非常遠,錄得強風似乎因副高西南沿的東南氣流疊加所致。預料驟雨仍會於明天影響香港,但強度將逐漸減弱。

Next Update 下次更新

Unless VICENTE maintains its current strength tomorrow night, this is the final bulletin on VICENTE.

除非韋森特明晚並未明顯減弱,否則這是本站對韋森特的最後一次發佈。

Overview 總覽

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.

韋森特於登陸前繼續增強,聯合颱風警報中心基於風暴型態比初時分析明顯為佳而修訂昨晚 8 時之強度估計。在上午 2 時,韋森特集結在香港天文台西南約 100 公里 (55 海里)。天文台於凌晨 12 時 45 分發出十號颶風信號,是自 1999 年 9 月颱風約克吹襲以來首次。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

VICENTE is expected to move WNW in the southwestern periphery of the subtropical ridge. As the ridge re-extends westwards, VICENTE will start to move west after t+12.

韋森特將沿副熱帶高壓脊西南部向西北偏西移動。隨著該脊逐漸西伸,韋森特將於 12 小時後改為向西移。

Intensity Analysis 強度分析

Current T-number: T6.0/6.0/D2.5/24 HRS; D1.5/06 HRS
VICENTE has developed a wide central dense overcast, enclosing its eye. VICENTE is expected to weaken rapidly after landfall.

現時的 T 號碼: T6.0/6.0/D2.5/24 HRS; D1.5/06 HRS
韋森特發展出廣闊的中心密集雲區,完全包圍其風眼。預料韋森特將於登陸後快速減弱。

Effects on Hong Kong 對香港的影響

[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.

本港普遍吹烈風,而香港西南部正非常靠近眼牆。長洲於過去一小時曾錄得 10 分鐘持續風速達每小時 136 公里,遠超颶風標準下限。韋森特正最接近香港,本地風向將轉為東南。隨著韋森特於未來一兩小時登陸,風勢將開始減弱。狂風驟雨將繼續於今天影響香港。

於低窪地區居住人士請留意由風暴潮造成的海水倒灌。

Overview 總覽

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.

韋森特快速增強至二級颱風上限強度。在午夜 12 時,韋森特集結在香港西南偏南約 110 公里 (60 海里)。天文台於下午 11 時 20 分發出九號烈風或暴風增強信號。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

VICENTE is expected to move NW in the southwestern periphery of the subtropical ridge. The ridge will re-extend westwards and this will cause VICENTE to move west after t+12.

韋森特將沿副熱帶高壓脊西南部向西北移動。預料該脊將西伸,韋森特將於 12 小時後改為向西移。

Intensity Analysis 強度分析

Current T-number: T5.0/5.0/D2.0/24 HRS; D0.5/04 HRS
VICENTE's eye has consolidated and is clearly visible on IR satellite imagery. In its current trend, VICENTE will continue to intensify before making landfall, and will weaken rapidly after landfall.

現時的 T 號碼: T5.0/5.0/D2.0/24 HRS; D0.5/04 HRS
韋森特的風眼整固,於紅外線衛星雲圖中清晰可見。按照目前趨勢,預料韋森特將繼續增強至登陸,隨後快速減弱。

Effects on Hong Kong 對香港的影響

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.

風勢入夜後明顯增強,市區很多地方正吹烈風,離岸及高地更吹暴風或颶風。預料風勢將繼續增強,而韋森特會於未來 3 至 4 小時最接近香港。風向將於今日 (7 月 24 日) 早段逐漸順轉為東南,且伴隨頻密狂風驟雨。

於低窪地區居住人士請留意上午 2 時的漲潮可能令海水倒灌。請留意韋森特的最新發展。

Overview 總覽

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.

韋森特向西北至西北偏北移動,並於過去 6 小時稍為增強。在下午 8 時,韋森特集結在香港以南約 150 公里 (80 海里)。天文台於下午 5 時 40 分發出八號東北烈風或暴風信號。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

VICENTE is expected to move NW in the southwestern periphery of the subtropical ridge. The ridge will re-extend westwards and this will cause VICENTE to move west after t+24.

韋森特將沿副熱帶高壓脊西南部向西北移動。預料該脊將西伸,韋森特將於 24 小時後改為向西移。

Intensity Analysis 強度分析

Current T-number: T4.5/4.5/D1.5/24 HRS; D0.5/09 HRS
VICENTE has developed a well-defined eye. The storm should maintain its current strength or intensify slightly before making landfall, and will weaken rapidly after landfall.

現時的 T 號碼: T4.5/4.5/D1.5/24 HRS; D0.5/09 HRS
韋森特已發展出一明顯風眼。預料韋森特將於登陸前維持強度或稍為增強,隨後快速減弱。

Effects on Hong Kong 對香港的影響

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.

按照目前預測路徑,韋森特可能於今晚進入香港 100 公里範圍。本港多處地方正吹東北烈風,部分風勢更為強烈。風向將於今晚逐漸順轉為東南,而由於韋森特繼續靠近,風力將進一步提升,且伴隨頻密狂風驟雨。請即完成所有預防措施,並留意熱帶氣旋的最新發展。

Overview 總覽

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.

韋森特繼續增強至颱風強度,並於過去 6 小時向北穩定地緩慢移動。在上午 11 時,韋森特集結在香港東南偏南約 270 公里 (150 海里)。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

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.

受副熱帶高壓脊和赤道反氣旋的影響,韋森特開始向北移動。預料副高將於短期內重新西伸;同時,隨著韋森特北移,赤道反氣旋的影響將減退,韋森特將轉回向偏西方向移動。

Intensity Analysis 強度分析

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.

現時的 T 號碼: T4.0/4.0/D1.0/15 HRS
韋森特的對流成功捲至其東半圓,並似乎在建立雲捲風眼;其整體結構亦變得更為對稱。韋森特附近洋面持續高溫,輻散良好且風切較弱,有利風暴增強。預料韋森特將於登陸後逐漸減弱。

Effects on Hong Kong 對香港的影響

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.

由於韋森特北移,香港風向由偏東逆轉至東北,而現時部分地區已開始吹強風。隨著韋森特繼續靠近並增強,預料風力於未來 12 小時呈上升之勢。風向將於周二順轉至東南,而狂風驟雨將於未來兩天繼續影響本港。請盡早採取預防措施,並留意熱帶氣旋的最新發展。

Overview 總覽

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.

韋森特增強為強烈熱帶風暴,並幾乎停止移動。在下午 8 時,韋森特集結在香港東南偏南約 370 公里 (200 海里)。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

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.

受中國東部的一道西風槽影響,副熱帶高壓脊稍為東退;加上赤道反氣旋的存在,令韋森特缺乏前進動力,於過去 12 小時隨其發展而不規則地移動。預料此現象將於未來 12 小時持續,隨後預測副高將再度西伸,令韋森特西進並趨向廣東西部沿岸。

Intensity Analysis 強度分析

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。

Effects on Hong Kong 對香港的影響

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.

香港開始受狂風驟雨影響。隨著韋森特明天靠近本港,東至東北風將增強至強風或以上程度,風向於周二逐漸轉向東南。由於韋森特移速較慢,它影響香港的時間將比預期長。

Overview 總覽

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.

聯合颱風警報中心今天較早時升格 92W 為熱帶低氣壓 09W,而日本氣象廳於今晚升格該系統為熱帶風暴,並命名為韋森特。在下午 8 時,韋森特集結在香港東南約 460 公里 (250 海里)。天文台於下午 3 時 40 分發出一號戒備信號。

TC Naming 氣旋命名

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.

韋森特為熱帶氣旋名稱列表中第 139 個名字,由美國提供,為一查摩洛男性名字。此名字曾於 2005 年使用,當時該氣旋曾令香港天文台發出一號戒備信號。

Movement Analysis 路徑分析

VICENTE is expected to move WNW along the southwestern periphery of the subtropical ridge. Irregularities may occur as the storm organizes itself.

預料韋森特將沿副熱帶高壓脊西南面向西北偏西移動,但由於風暴仍較不穩定,組織時或會造成路徑不規則的現象。

Intensity Analysis 強度分析

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。

Effects on Hong Kong 對香港的影響

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.

極端高溫引發雷暴和大雨,於傍晚影響本港。預料天氣將於明日轉壞,東至東北風會增強,並於明晚至周一早段逐漸順轉至東南風。香港未來兩天將有狂風驟雨。

Overview 總覽

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.

香港天文台將位於呂宋東面的熱帶擾動 92W 升格為熱帶低氣壓。在下午 8 時,92W 集結在馬尼拉東北偏北約 420 公里 (230 海里)。

Movement Analysis 路徑分析

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.

副熱帶高壓脊西伸至華南,而 92W 正處於脊場中心之西南面。預料 92W 於未來 24 小時向西北偏西移動,進入南海,到達較高緯度後轉為向西移。

Intensity Analysis 強度分析

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。

Effects on Hong Kong 對香港的影響

Subsidence associated with 92W will bring very hot and hazy weather to Hong Kong tomorrow and on Sunday. Winds will strengthen from the northeast later on Sunday with squally showers.

與 92W 相關連的下沉氣流將於明日及星期日為本港帶來酷熱和有煙霞的天氣。東北風將於周日後期增強,並伴隨狂風驟雨。
