Overview 總覽

UTOR made landfall at Yangjiang yesterday and moved NW turning to N after landfall. At 2 pm, UTOR was centred about 370 km (200 NM) WNW of Hong Kong. The #1 Standby Signal was issued at 1:40 am and was lifted at 4:40 pm.

尤特於昨日登陸陽江,隨後向西北轉北移動。在下午 2 時,尤特集結在香港西北偏西約 370 公里 (200 海里)。天文台於凌晨 1 時 40 分發出一號戒備信號,後於下午 4 時 40 分取消。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

UTOR appears stuck in an area of weak shear environment as the subtropical ridge moved north. Currently slow movement towards the north is expected in the next 24 hours.

因副熱帶高壓脊北抬,尤特看似停滯於一弱流場環境,最新一佈預測尤特會於未來 24 小時緩慢向北移動。

Intensity Analysis 強度分析

Current T-number: N/A
Supply of moisture from the south lowers UTOR's weakening rate. However as the storm digs further inland, it will still lose intensity and is expected to weaken into an area of low pressure in the next 24 hours.

現時的 T 號碼: 不適用
由於南面有水氣提供,尤特減弱速度沒有預期般快。但隨著風暴繼續深入內陸,它仍然會減弱並預計於 24 小時內減弱為低壓區。

Effects on Hong Kong 對香港的影響

As UTOR loses intensity, winds in Hong Kong should diminish gradually in the next 24 hours. However, UTOR and its remnants will still bring showers to the territory in the next few days.

隨著尤特減弱,本地風力將於未來 24 小時進一步下降,但尤特及其殘餘雨帶將於未來數天繼續為香港帶來驟雨。

Overview 總覽

UTOR is approaching western Guangdong and has been moving NNW in the past 6 hours. At 2 pm, UTOR was centred about 230 km (130 NM) WSW of Hong Kong. The #8 SE Gale or Storm Signal was replaced by the #3 Strong Wind Signal at 1:40 pm.

尤特正靠近廣東西部,並於過去 6 小時向西北偏北移動。在下午 2 時,尤特集結在香港西南偏西約 230 公里 (130 海里)。天文台於下午 1 時 40 分發出三號強風信號,取代八號東南烈風或暴風信號。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

The subtropical ridge is about to extend westward and UTOR is expected to turn equatorward inland.

副熱帶高壓脊即將開始向西伸展,預料尤特會於內陸逐漸轉向偏西移動。

Intensity Analysis 強度分析

Current T-number: T4.0/5.0/W1.0/24 HRS
UTOR is weakening due to land interaction. The storm is expected to weaken rapidly upon landfall and dissipate in 48 hours' time.

現時的 T 號碼: T4.0/5.0/W1.0/24 HRS
受陸地影響尤特開始減弱,預料其減弱速度會於登陸後加快,並於 48 小時內消散。

Effects on Hong Kong 對香港的影響

Despite the lowering of the #8 Signal, UTOR is actually closest to Hong Kong now and winds did not weaken substantially today, and gales are still observed at southwestern Hong Kong. However, UTOR is about to make landfall near Yangjiang, and as the storm weakens winds will die down. Squally showers will continue to affect the territory tonight and tomorrow.

雖然八號信號已解除,但尤特現時最為接近本港,今天風力沒有明顯減弱,香港西南部仍有烈風。但是,尤特即將登陸陽江,風暴減弱時本地風力將下降。狂風驟雨仍會於今晚及明天影響香港。

Overview 總覽

UTOR has started to move NW. At 2 am, UTOR was centred about 310 km (170 NM) SSW of Hong Kong. The #8 SE Gale or Storm Signal was issued at 1:40 am.

尤特開始向西北移動。在上午 2 時,尤特集結在香港西南偏南約 310 公里 (170 海里)。天文台於凌晨 1 時 40 分發出八號東南烈風或暴風信號,取代強風信號。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

Movement Analysis 路徑分析

UTOR has decelerated significantly. The storm will move NW along a weakness in the subtropical ridge towards western Guangdong. The ridge is expected to strengthen again later leading to an equatorward turn.

尤特已經明顯減速。預料風暴將沿副熱帶高壓脊弱點向西北移動,趨向廣東西部。副高將於稍後時間再度增強,尤特移向將轉為偏西。

Intensity Analysis 強度分析

Current T-number: T5.0/5.5/W0.5/24 HRS
UTOR's northern structure deteriorated slightly, but convections remain tight. The storm is expected to maintain current intensity until landfall, and weaken rapidly afterwards.

現時的 T 號碼: T5.0/5.5/W0.5/24 HRS
尤特北面結構稍為轉差,但對流仍然緊密。預料風暴會於登陸前維持強度,隨後急速減弱。

Effects on Hong Kong 對香港的影響

UTOR is expected to be closest to Hong Kong today around noon at a distance between 250 and 300 km. Winds are expected to strengthen and turn southeast soon, reaching gale force. Squally showers will continue to affect Hong Kong throughout today. Landfall is expected today evening or early nighttime; winds will start to subside by that time.

尤特將於今天中午時份最接近本港,於香港 250 至 300 公里外掠過。預料風勢將繼續增強至烈風程度,風向將順轉至東南。狂風驟雨會於今天整日影響本港。尤特將於傍晚或晚間早段登陸,屆時風力會開始減弱。

Overview 總覽

UTOR is now crossing the South China Sea with signs of intensification. At 2 pm, UTOR was centred about 380 km (200 NM) S of Hong Kong. The #3 Strong Wind Signal was issued at 4:40 am, replacing the Standby Signal.

尤特正橫過南海,並有跡象增強。在下午 2 時,尤特集結在香港以南約 380 公里 (200 海里)。天文台於清晨 4 時 40 分發出三號強風信號,取代戒備信號。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

A weakness is seen west of the subtropical ridge which has continued to retreat, and in response to this UTOR has slowed down significantly in the past few hours. A change towards a more poleward direction is imminent. UTOR is expected to move northwest in the next 36 hours towards western Guangdong. Thereafter the ridge is expected to strengthen again and storm motion should turn equatorward.

副熱帶高壓脊繼續東退,其西沿可見到一弱點,尤特因此於過去數小時明顯減速。預料尤特即將採取較為偏北的方向移動,於未來 36 小時內登陸廣東西部。其後副高有望再度增強,尤特移向將轉為偏西。

Intensity Analysis 強度分析

Current T-number: T5.5/5.5/D1.5/24 HRS
UTOR has developed a banding eye, while convections are becoming more symmetrical and expanding outward. The storm is expected to intensify slightly prior to landfall, after which rapid weakening will take place.

現時的 T 號碼: T5.5/5.5/D1.5/24 HRS
尤特發展出雲捲風眼,對流變得更為對稱且向外擴展。預料風暴會於登陸前稍為增強,隨後急速減弱。

Effects on Hong Kong 對香港的影響

UTOR's rainbands are now affecting Hong Kong and northeasterly winds are gradually reaching strong force, with occasional gales in offshore areas and on high ground. As UTOR draws closer winds will continue to strengthen tonight, gradually veering to southeast tomorrow. As the storm is expected to decelerate, inclement weather conditions will persist on Wednesday, and probably extending to early Thursday as well. Squally showers will also affect the territory, and will be heavy at times.

尤特的雨帶正影響本港,部分地方吹達強風程度東北風,而離岸及高地間中受烈風吹襲。隨著尤特移近,本港風勢將於今晚進一步加強,風向於明天順轉至東南。由於預測尤特會減速移動,惡劣天氣將於周三整天影響本港,並可能持續至周四早段。狂風驟雨將繼續侵襲本港,雨勢有時頗大。

Overview 總覽

UTOR made impact at Luzon early today and entered the South China Sea this morning. It has weakened into a category 2 typhoon. At 2 pm, UTOR was centred about 770 km (420 NM) SE of Hong Kong. The #1 Standby Signal was issued at 4:05 pm.

尤特今天凌晨時份登陸呂宋,於今早進入南海,並減弱為二級颱風。在下午 2 時,尤特集結在香港東南約 770 公里 (420 海里)。天文台於下午 4 時 05 分發出一號戒備信號。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

The subtropical ridge continued to weaken but maintains substantial strength in southeastern China. UTOR is expected to move WNW quickly across the South China Sea in the next 24 hours. However, a mid-latitude trough propagating eastwards will erode the ridge and allow a more poleward movement beyond t+24/36. A landfall at western Guangdong is predicted.

副熱帶高壓脊繼續減弱,但於中國東南部仍然保持一定勢力,預料尤特將於未來 24 小時向西北偏西快速移動,橫過南海。一道向東移動的西風槽將侵蝕副高,並令尤特的路徑於 24 至 36 小時後開始偏北,預料尤特會於廣東西部登陸。

Intensity Analysis 強度分析

Current T-number: T4.0/5.0/W2.0/24 HRS
UTOR's lower-level structure was destroyed as it crossed the mountainous Luzon terrain. The storm appears to be re-organizing its structure and some intensification is expected due to warm seas and low vertical wind shear. UTOR may reach category 3 typhoon strength again at landfall.

現時的 T 號碼: T4.0/5.0/W2.0/24 HRS
尤特經過呂宋高山令低層結構被破壞,而由雲圖看來它正逐漸重新組織其結構。在高海溫及低垂直風切變的環境下,預料尤特將能於南海增強,登陸時有望再度成為三級颱風。

Effects on Hong Kong 對香港的影響

It will still be hot tonight. UTOR's rainbands will start to affect Hong Kong tomorrow, and winds will strengthen from the E/NE, veering to SE on Wednesday. According to the present track, strong force winds or above are expected. There will be squally showers, becoming more frequent on Wednesday.

本港今晚仍然較為炎熱。尤特的雨帶將於明天開始影響本港,東或東北風將會增強,並於周三順轉為東南風。按照目前預測路徑,預料本港最少會吹強風。香港將受狂風驟雨侵襲,雨勢於周三漸轉頻密。

Overview 總覽

UTOR continued to intensify and is now a category 4 typhoon. At 2 pm, UTOR was centred about 400 km (220 NM) E of Manila.

尤特繼續增強至四級颱風強度。在下午 2 時,尤特集結在馬尼拉以東約 400 公里 (220 海里)。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

The western edge of the subtropical ridge has weakened slightly, while there seems to be some strengthening to the east of UTOR. The storm is expected to move WNW under the southern periphery of the ridge, reaching Luzon tomorrow. UTOR's track may turn equatorward again as it reaches the southern edge of the ridge, but model forecasts are calling for a retreat of the ridge at later taus that will induce a turn to the NW.

副熱帶高壓脊西沿稍為減弱,而尤特東面脊場有所加強,這將令尤特沿副高南部向西北偏西移動,於明天到達呂宋。隨著尤特到達副高南沿,其移向或會再次轉西,但預報模式顯示副高會於預測後期減弱,使尤特逐漸向西北移。

Intensity Analysis 強度分析

Current T-number: T6.0/6.0/D1.5/24 HRS
UTOR has developed a symmetrical central dense overcast and a well-defined eye started to appear this morning, leading to a rapid upward adjustment to its intensity. Further intensification is expected before landfall, but UTOR is now forecast to land on the most hilly parts of Luzon which will cause substantial impact to its intensity. As UTOR enters South China Sea, high sea temperatures should allow some re-development.

現時的 T 號碼: T6.0/6.0/D1.5/24 HRS
尤特發展出一對稱中心密集雲區,清晰風眼於今晨開始見到,令其強度大幅提升。預料尤特將於登陸前繼續增強,但由於預測尤特會經過呂宋較高的山脈,它可能於橫過菲律賓期間明顯減弱。風暴進入南海後將繼續受惠於高海溫而能重新發展。

Effects on Hong Kong 對香港的影響

Very hot weather is still expected tomorrow. As UTOR enters the South China Sea, northeasterly winds will strengthen on Tuesday, veering to southeast the next day. Squally showers will affect the territory in the middle of this week.

香港明天天氣仍然酷熱。隨著尤特進入南海,東北風將於周二增強,翌日順轉至東南。本周中期本港將有狂風驟雨。

Overview 總覽

11W rapidly intensified into a typhoon over the past 24 hours, and was named UTOR by the JMA early today. At 2 pm, UTOR was centred about 890 km (480 NM) E of Manila.

11W 於過去 24 小時急劇增強為一颱風,並於今天較早時被日本氣象廳命名為尤特。在下午 2 時,尤特集結在馬尼拉以東約 890 公里 (480 海里)。

TC Naming 氣旋命名

UTOR is the 27th name in the tropical cyclone name list. It was contributed by the United States, and is the Marshallese word for squall line. This name was used in 2001 and 2006, with the former occurrence necessitating the #8 Gale or Storm Signal in Hong Kong.

尤特為熱帶氣旋名稱列表中第 27 個名字,由美國提供,在馬紹爾語中解作颮線。此名曾於 2001 及 2006 年使用,前者令香港天文台發出八號烈風或暴風信號。

Movement Analysis 路徑分析

The subtropical ridge north of UTOR is firmly anchored near Kyushu. Under its influence the storm is expected to track WNW in general. However, a disturbance appears to be developing in the South China Sea, and may induce further uncertainty to UTOR's track.

於尤特北面的副熱帶高壓脊處於強勢,中心於日本九州一帶,在其影響下預料尤特將大致向西北偏西移動。另一方面,一擾動似乎正於南海發展,這可能增加尤特路徑之不確定性。

Intensity Analysis 強度分析

Current T-number: T4.5/4.5/D2.5/24 HRS
Due to improving outflow and minimal shear, UTOR has intensified rapidly over the past 24 hours from a tropical depression to a typhoon. Such favourable environmental conditions are expected to continue in the next 24 to 36 hours, allowing UTOR to intensify further. Impact at Luzon will weaken the system, but it may re-intensify in the South China Sea. Again due to the presence of the tropical disturbance in the South China Sea intensity forecast is subject to high uncertainty.

現時的 T 號碼: T4.5/4.5/D2.5/24 HRS
由於輻散轉好且垂直風切變微弱,尤特於過去 24 小時由熱帶低氣壓急劇增強為颱風。預料此良好大氣環境將於未來 24 至 36 小時維持,令尤特繼續增強。登陸呂宋將令風暴減弱,但它於南海仍有增強空間。同樣地於南海的熱帶擾動或會增加尤特的強度預測誤差。

Effects on Hong Kong 對香港的影響

According to the present track, UTOR's subsidence will inflict very hot and hazy weather on Monday as the storm crosses Luzon. Northeasterly winds will strengthen on Tuesday, veering to southeast the next day. Squally showers will affect the territory in the middle of next week.

按照目前預測路徑,尤特將於周一橫過呂宋,其下沉氣流將使香港受煙霞及酷熱天氣影響。東北風將於周二增強,翌日順轉至東南。下周中期本港將有狂風驟雨。

Movement Analysis 路徑分析

A subtropical ridge is situated north of 11W. Under its steering influence, the storm is expected to move WNW in the next three days.

副熱帶高壓脊處於 11W 以北,預料將於未來三天帶領風暴向西北偏西移動。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/INT OBS
11W is a small system and is intensifying. Vertical wind shear is extremely low in Philippine Sea and sea temperatures are high. The storm is expected to develop gradually over the next few days.

現時的 T 號碼: T2.0/2.0/INT OBS
11W 尺度小,正開始增強。由於菲律賓以東海域垂直風切變極低而海溫頗高,預料 11W 會於未來數天逐漸發展。

Effects on Hong Kong 對香港的影響

As 11W nears Luzon three days later, hazy weather could affect Hong Kong on Monday.

隨著 11W 於三天後靠近呂宋一帶,香港或會於下周一受煙霞影響。
