GONI was relocated today as its low-level circulation centre escaped from the main cloud bands. It travel NE rapidly and weakened into a tropical depression earlier. At 20 HKT, GONI was centred about 320 km (170 NM) SSW of Hong Kong.

天鵝的低層環流中心脫離主要雲帶,於今午被重新定位,其後向東北快速移動。在 20 HKT,天鵝集結在香港西南偏南約 320 公里 (170 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty.

  • The English spelling was changed from KONI in 2008.
  • The name was last used in 2003; the storm associated with this name necessitated the #1 Standby Signal.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。該名稱曾於 2003 年使用,並令本港發出一號戒備信號。

GONI is lingering near Hainan Island. At 08 HKT, GONI was centred about 290 km (160 NM) SW of Haikou.

天鵝於海南島附近徘徊。在 08 HKT,天鵝集結在海口西南約 290 公里 (160 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty.

  • The English spelling was changed from KONI in 2008.

Movement Analysis 路徑分析

Interactions with MORAKOT may cause GONI to travel east in the next 24 hours. Later on the dominant southwesterlies in the South China Sea will push GONI towards Guangdong.

與莫拉克的相互影響將可能令天鵝於未來 24 小時向東移動,其後受到西南氣流影響,它將向東北移並可能影響廣東沿岸。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/S0.0/24 HRS
Due to high wind shear and proximity to land, GONI could not intensify. It is expected GONI will maintain strength as it travels near Hainan Island, and will gradually weaken near landfall.

現時的 T 號碼: T2.0/2.0/S0.0/24 HRS
受到較高垂直風切變和接近陸地的影響,天鵝並不能增強預料天鵝於海南附近海域經過時只能維持強度,並於靠近廣東時減弱

Effects on Hong Kong 對香港的影響

Accoding to the present forecast track and intensity, swells may be present in Hong Kong waters later.

根據目前預測移動路徑和系統強度,香港鄰近海域將於稍後出現暗湧。

GONI has intensified slightly. At 08 HKT, GONI was centred about 230 km (120 NM) WSW of Haikou.

天鵝稍為增強。在 08 HKT,天鵝集結在海口西南偏西約 230 公里 (120 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty.

  • The English spelling was changed from KONI in 2008.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。該名稱曾於 2003 年使用,並令本港發出一號戒備信號。

Movement Analysis 路徑分析

Interactions with typhoon MORAKOT may cause GONI to travel south or southeast in the next 24 hours. After looping near Hainan Island, interaction between the storms is expected to weaken and GONI will travel north to make landfall in Guangdong.

與颱風莫拉克的相互影響將可能令天鵝於未來 24 小時向南或東南移動。經過海南東南部後,它和莫拉克的影響將逐漸減弱,並將逐漸向北移動,再度趨向廣東。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/S0.0/18 HRS
Under unfavourable environments, GONI is expected to maintain strength while it travels near Hainan. If it touches Hainan Island, it may even weaken to a tropical depression. Absorption by MORAKOT is still possible later, but is less likely as MORAKOT is weakening rather rapidly and is forecast to travel north.

現時的 T 號碼: T2.0/2.0/S0.0/18 HRS
受到不利環境影響,預料天鵝於海南附近海域經過時只能維持強度若天鵝橫過海南島陸地,受高山影響它將可能減弱為熱帶低氣壓雖然天鵝有機會被莫拉克吸收,但由於莫拉克登陸後大幅減弱且開始向北移,此可能性已減低

Effects on Hong Kong 對香港的影響

Accoding to the present forecast track and intensity, swells may be present in Hong Kong waters later.

根據目前預測移動路徑和系統強度,香港鄰近海域將於稍後出現暗湧。

GONI started to lose latitude this morning. At 14 HKT, GONI was centred about 310 km (170 NM) W of Hong Kong.

天鵝的路徑於今早開始出現向南分量。在 14 HKT,天鵝集結在香港以西約 310 公里 (170 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty.

  • The English spelling was changed from KONI in 2008.
  • The name was last used in 2003; the storm associated with this name necessitated the #1 Standby Signal.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。該名稱曾於 2003 年使用,並令本港發出一號戒備信號。

Movement Analysis 路徑分析

Interactions with typhoon MORAKOT may cause GONI to travel south, eventually reaching Hainan Island.

與颱風莫拉克的相互影響將可能令天鵝向南移動,趨向海南島一帶。

Intensity Analysis 強度分析

Current T-number: N/A
GONI is expected to remain on land for some time, and weakening into a tropical depression is likely in the next 24 hours. Numerical predictions call for absorption by typhoon MORAKOT in 2 days' time.

現時的 T 號碼: 不適用
由於天鵝將繼續經過陸地,預料它將於 24 小時內減弱為熱帶低氣壓。部分數值模式預報指出天鵝將於兩天內被颱風莫拉克吸收

Effects on Hong Kong 對香港的影響

Occasional showers might still affect the territory.

GONI has remained almost stationary in the past 12 hours. At 20 HKT, GONI was centred about 200 km (110 NM) W of Hong Kong.

天鵝於過去 12 小時幾乎停留不動。在 20 HKT,天鵝集結在香港以西約 200 公里 (110 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty. The English spelling was changed from KONI in 2008.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。

Movement Analysis 路徑分析

Weak steering rendered GONI almost stationary. Meanwhile, typhoon MORAKOT may move west in the next 72 hours towards Chinese mainland or Taiwan, and therefore it is possible that interactions between the storms will be more significant later. Such interactions may cause GONI to travel south.

弱駛流令天鵝移動緩慢。另一方面,預料颱風莫拉克將逐漸向西移動並趨向中國東部或台灣一帶;此兩個系統有機會於稍後靠近,其相互影響或會令天鵝向南移。

Intensity Analysis 強度分析

Current T-number: N/A
Weakening of the storm into a tropical depression is expected in the next 2 days.

現時的 T 號碼: 不適用
天鵝將於未來一兩天減弱為熱帶低氣壓

Effects on Hong Kong 對香港的影響

Occasional showers might still affect the territory.

本港間中或會受驟雨影響

GONI has made landfall near Taishan and is slowly moving west. At 08 HKT, GONI was centred about 180 km (100 NM) WSW of Hong Kong.

天鵝於台山附近登陸,並繼續向西緩慢移動。在 08 HKT,天鵝集結在香港西南偏西約 180 公里 (100 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty. The English spelling was changed from KONI in 2008.

Movement Analysis 路徑分析

Affected by a ridge near Taiwan and the westward extension of its influence, GONI will continue to move west. Meanwhile, severe tropical storm MORAKOT may move west in the next 72 hours towards Chinese mainland or Taiwan, and therefore it is possible that interactions between the storms will be more significant beyond t+48. Such interactions may cause GONI to loop.

位於台灣附近的高壓區令天鵝向西移動。另一方面,預料強烈熱帶風暴莫拉克將逐漸向西移動並趨向中國東部或台灣一帶;此兩個系統有機會於 t+48 以後再度靠近,其相互影響或會令天鵝打轉。

Intensity Analysis 強度分析

Current T-number: N/A
A general weakening trend has started. However the rate of weakening depends highly on whether the storm is embedded deep in land; weakening rate could be lower if GONI skirted the coastal areas instead.

現時的 T 號碼: 不適用
天鵝已開始減弱,但減弱速度將取決於天鵝進入內陸之深淺,如天鵝只掃過沿岸地區,減弱速度或會較低

Effects on Hong Kong 對香港的影響

Occasional strong southerly winds will be observed in offshore waters and on high grounds.

本港離岸地區和高地將間中吹偏南強風

Intensity Analysis 強度分析

Current T-number: T3.5/3.5/S0.0/06 HRS

天鵝將開始減弱,但減弱速度將取決於天鵝進入內陸之深淺,如天鵝只掃過沿岸地區,減弱速度或會較低

Effects on Hong Kong 對香港的影響

Southeasterly winds, changing gradually to southerly, are expected to remain strong in the next few hours, and occasional squalls may be observed as Hong Kong is hit by GONI's rain bands. GONI has passed its closest approach to Hong Kong.

本港東南強風將於未來數小時維持,並逐漸轉為偏南風;當天鵝的雨帶掃過香港時,陣風可能仍然猛烈天鵝已過最接近香港的位置

GONI intensified significantly, and its circulation appears tight on radar. Force 11 winds (sustained) were reported at Huangmao Zhou earlier. At 20 HKT, GONI was centred about 110 km (60 NM) SW of Hong Kong. The #8 SE Signal was issued at 21:40 HKT.

天鵝明顯增強,從雷達上看其環流頗為緊密。黃茅洲較早前曾錄得持續風速達 11 級。在 20 HKT,天鵝集結在香港西南約 110 公里 (60 海里)。天文台於 21:40 HKT 改發八號東南烈風或暴風信號

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty. The English spelling was changed from KONI in 2008.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。

Movement Analysis 路徑分析

A ridge has developed north of Taiwan, and GONI is situated in its southwestern periphery. Therefore NW to NNW movement is expected before landfall. The ridge's influence is seen extending west at above 23°N, and thus GONI may track westward after landfall. The disturbance east of GONI has intensified into tropical storm MORAKOT and may move west in the next 72 hours, and therefore it is possible that interactions between the storms will be more significant beyond t+72. Such interactions may cause GONI to loop.

一個微弱高壓區於台灣北部建立,其影響向西面伸展。預料在它的影響下,天鵝將向西北或西北偏北移動直至登陸,其後將轉向偏西移動。天鵝以東的一熱帶擾動已增強為熱帶風暴莫拉克,並預料逐漸向西移動;此兩個系統有機會於 t+72 以後再度靠近,其相互影響或會令天鵝打轉。

Intensity Analysis 強度分析

Current T-number: T3.5/3.5/D1.0/06 HRS
GONI should maintain strength in the next 6 to 12 hours. Rapid weakening follows as landfall is made. However it depends highly on whether the storm is embedded deep in land; weakening rate could be lower if GONI skirted the coastal areas instead.

現時的 T 號碼: T3.5/3.5/D1.0/06 HRS
天鵝將於未來 6 至 12 小時維持強度,並於登陸後迅速減弱;減弱程度取決於天鵝進入內陸之深淺,如天鵝只掃過沿岸地區,減弱速度或會較低

Effects on Hong Kong 對香港的影響

Winds are expected to strengthen from the east/southeast, changing to south overnight and reaching gale force. Western parts of Hong Kong will be affected more severely as places there are closer to the storm.

GONI is expected to be closest to Hong Kong in the following few hours.

本港東至東南風將增強至烈風程度,稍後將轉為南風由於香港西部距離天鵝較近,該區風勢將更為強勁

天鵝將於未來數小時最為接近香港

GONI moved northwest last night, continuing to intensify in the interim. At 08 HKT, GONI was centred about 180 km (100 NM) S of Hong Kong. The #3 Strong Wind Signal was issued at 11:15 HKT.

天鵝昨晚向西北移,並繼續增強。在 08 HKT,天鵝集結在香港以南約 180 公里 (100 海里)。天文台已於上午 11 時 15 分發出三號強風信號

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty. The English spelling was changed from KONI in 2008.

天鵝一名由南韓提供。天鵝為一種體積大而優雅,羽毛通常呈白色,頸部瘦而長的雀鳥,生活在河流或湖泊上。冬天的時候由西伯利亞飛往韓國生活。它象徵忠誠。

Movement Analysis 路徑分析

A ridge has developed north of Taiwan, and GONI is situated in its southwestern periphery. Therefore NW to NNW movement is expected before landfall. The ridge's influence is seen extending west at above 23°N, and thus GONI may track westward after landfall. The disturbance east of GONI has intensified into tropical storm MORAKOT and may move west in the next 72 hours, and therefore it is possible that interactions between the storms will be more significant beyond t+72. Such interactions may cause GONI to loop.

一個微弱高壓區於台灣北部建立,其影響向西面伸展。預料在它的影響下,天鵝將向西北或西北偏北移動直至登陸,其後將轉向偏西移動。天鵝以東的一熱帶擾動已增強為熱帶風暴莫拉克,並預料逐漸向西移動;此兩個系統有機會於 t+72 以後再度靠近,其相互影響或會令天鵝打轉。

Intensity Analysis 強度分析

Current T-number: T2.5/2.5/D0.5/18 HRS
GONI is expected to intensify slightly before landfall due to favourable sea temperatures and moisture content. Rapid weakening follows as landfall is made. However it depends highly on whether the storm is embedded deep in land; weakening rate could be lower if GONI skirted the coastal areas instead.

現時的 T 號碼: T2.5/2.5/D0.5/18 HRS
由於南海水溫仍高,預料天鵝將於登陸前稍為增強,但登陸後應迅速減弱;減弱程度取決於天鵝進入內陸之深淺,如天鵝只掃過沿岸地區,減弱速度或會較低

Effects on Hong Kong 對香港的影響

Rainbands associated with GONI will affect Hong Kong in the next few days, and winds will strengthen from the east to northeast. Winds are expected to turn gradually to southeast in a clockwise manner.

天鵝的雨帶將於未來幾日影響香港,而香港初時將吹東至東北風;風勢將逐漸增強預料稍後風向將逐漸以順時針方向轉向東南

08W intensified into a tropical storm tonight and was named GONI by the JMA. At 20 HKT, GONI was centred about 340 km (180 NM) SSE of Hong Kong.

08W 於晚上增強為熱帶風暴,並被日本氣象廳命名為天鵝。在 20 HKT,天鵝集結在香港東南偏南約 340 公里 (180 海里)。

TC Naming 氣旋命名

GONI was contributed by South Korea, meaning swan in English. A swan is a large graceful, usually white, bird with a long thin neck that lives on rivers, lakes, etc. It flies to Korea from Siberia in winter, and is a symbol of loyalty. The English spelling was changed from KONI in 2008.

Movement Analysis 路徑分析

GONI is expected to travel north, and with the strengthening of the ridge in China it is expected to turn west before landfall. The disturbance east of GONI may develop and move west, and therefore it is possible that interactions between the storms will be more significant beyond t+72. Such interactions may contribute to the eastward motion of the storm. However this is subject to a large uncertainty, and track forecast beyond t+72 is drawn with lower confidence.

預料於中國的高壓將於稍後增強,並令天鵝向偏西方向移動。天鵝以東的一熱帶擾動正逐漸發展,並預料逐漸向西移動;此兩個系統有機會於 t+72 以後再度靠近,其相互影響或會令天鵝向東南移。但由於此預測不確定性甚高,本發佈 t+72 以後的預測誤差可能較大。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/S0.0/06 HRS
GONI has settled down to having one rotation centre, but convections are constantly displaced to the west. Conditions in the South China Sea are still favourable for development, but shear has increased a bit. GONI is expected to intensify before landfall, and weakening trend should be observed after landfall as moist air is cut off.

現時的 T 號碼: T2.0/2.0/S0.0/06 HRS
天鵝對流仍未能集中在低層環流中心附近南海環境不俗,但垂直風切變稍為增加預料天鵝將於登陸前稍為增強,登陸後由於水氣供應減少而將減弱

Effects on Hong Kong 對香港的影響

Rainbands associated with GONI will affect Hong Kong in the next few days, and winds will strengthen from the northeast tomorrow. However the exact effects to Hong Kong will depend on its future movement which is quite uncertain at this point in time.

93W was upgraded to tropical depression 08W by the JTWC today. The depression also started to move north last night. At 14 HKT, 08W was centred about 400 km (220 NM) SSE of Hong Kong. The Observatory issued the #1 Standby Signal at 15:15 HKT.

93W 今天被聯合颱風警報中心升格為熱帶低氣壓 08W;該系統亦於今天凌晨開始北移。在 14 HKT,08W 集結在香港東南偏南約 400 公里 (220 海里)。天文台於下午 3 時 15 分發出一號戒備信號

TC Naming 氣旋命名

(Storm not yet named 氣旋並未命名)

Movement Analysis 路徑分析

08W has responded to the weakening of the ridge north of it and started its northward journey. It is expected that the subtropical ridge will gradually extend to the west at a relatively low latitude to allow temporary NNE/NE movement of the storm, and later on the high pressure in China will consolidate again to provide westward component in 08W's motion. Track speed is expected to be low as a result of weak steering.

Another disturbance east of 08W is developing. However as their separation is quite large at this moment, interaction between them is not likely, at least for the next 3 days.

由於 08W 北面脊場減弱,它於今日凌晨開始向北移動。預料副熱帶高壓脊將於低緯度地區西伸,令 08W 短暫向東北偏北或東北移動,後期於中國的高壓有可能再次增強,並令 08W 路徑出現西向量。由於駛流微弱,預料 08W 將移動緩慢。

08W 以東的一熱帶擾動正逐漸發展,但由於它和 08W 的距離頗遠,預料它們暫時將不會有相互影響。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/D0.5/24 HRS
08W has settled down to having one rotation centre, but convections are constantly displaced to the west. Conditions in the South China Sea are still favourable for development, but shear has increased a bit. Nevertheless, tropical storm strength is still expected some time in the next 72 hours.

現時的 T 號碼: T2.0/2.0/D0.5/24 HRS
08W 終於整合至只有一個低層環流中心,但對流仍處於該中心西面南海環境不俗,但垂直風切變稍為增加預料 08W 應可最少增強至熱帶風暴強度

Effects on Hong Kong 對香港的影響

Rainbands associated with 08W will affect Hong Kong in the next few days, and winds might strengthen starting from tomorrow. However the exact effects to Hong Kong will depend on its future movement which is quite uncertain at this point in time.

A major relocation took place last night, with 93W now situating in the South China Sea. At 14 HKT, 93W was centred about 600 km (320 NM) SE of Hong Kong.

昨夜 93W 被重新定位,現已位於南海北部。在 14 HKT,93W 集結在香港東南約 600 公里 (320 海里)。

TC Naming 氣旋命名

(Storm not yet named 氣旋並未命名)

Movement Analysis 路徑分析

A relocation was made earlier to reflect the situation most consistent with what the wind field suggests (Wind speeds in the Philippines have shifted to SW). The ridge north of 93W is weakening and thus 93W is not expected to maintain westward movement beyond t+24. However later movement remains largely uncertain:

  1. According to some numerical models, a disturbance east of 93W may develop and affect 93W's path. If this occurs, a eastward component in track direction should be observed;
  2. The subtropical ridge now in western Pacific could extend westward, contributing to a north or northeastern motion as low-latitude extension is likely.

However, there is a high confidence that 93W will move slowly in the South China Sea, due to the uncertain and weak steering flow.

93W 於昨晚被重新定位,使之與風場所示的位置一致 (菲律賓北部的風向轉為西南)。93W 以北的高壓脊將減弱,因此預料 93W 於未來 24 小時會停止大幅西移,但其未來路向仍不明朗 :

  1. 一些數值模式預計 93W 以東的擾動將有所增強;此舉或會令這兩個系統互相影響,93W 因而可能向東移;
  2. 現於西北太平洋的副熱帶高壓脊或會西伸,尤其是在低緯度地區;這或會令 93W 向北或東北移動

由於 93W 附近淨駛流微弱,唯一較為肯定的是它將會於未來數天緩慢移動。

Intensity Analysis 強度分析

Current T-number: T1.5/1.5/S0.0/24 HRS
Conditions are favourable in the South China Sea. However 93W still needs some time in consolidating its structure and improving cloud banding; once these procedures are completed, intensification is quite likely.

現時的 T 號碼: T1.5/1.5/S0.0/24 HRS
南海的環境頗佳,但預料 93W 仍需一段時間來整合其組織和附近環流;在整合完畢後它應可在有利環境下增強

Effects on Hong Kong 對香港的影響

Subsidence associated with the cyclone is expected to bring very hot and hazy weather to Hong Kong in the next few days.

與該系統相關的下沉氣流將會於未來數天為本港帶來酷熱及有煙霞的天氣

Tropical disturbance 93W over the Philippine Sea has intensified into a tropical depression. At 14 HKT, 93W was centred about 540 km (290 NM) ENE of Manila.

菲律賓以東的熱帶擾動 93W 已增強為熱帶低氣壓。在 14 HKT,93W 集結在馬尼拉東北偏東約 540 公里 (290 海里)。

TC Naming 氣旋命名

(Storm not yet named 氣旋並未命名)

Movement Analysis 路徑分析

The ridge north of 93W has contributed to its persistent westward track, but is now weakening rapidly and there is a wide pressure col north of 93W. It is expected that 93W will gradually turn north along the col, due to the steering from the subtropical ridge east of 93W. Due to the large coverage and instability of the system, the development of another centre west of the current one cannot be ruled out.

93W 以北的高壓脊令其持續向西移動,但該脊正在急速減弱,93W 北面因而出現一個氣壓鞍。預料 93W 稍後將由受到其東面副熱帶高壓脊的影響而北移至該鞍場。由於此系統巨大且不穩定,於現中心西面形成新中心的機會不能抹殺。

Intensity Analysis 強度分析

Current T-number: T1.5/1.5/INT OBS
Vertical wind shear is quite high south of 93W due to the persistent low-level southwesterlies, and convection is sheared to the west with the most intense rainbands situating in the South China Sea. As 93W moves north and away of the strong shear, gradual intensification is expected.

現時的 T 號碼: T1.5/1.5/INT OBS
93W 南部持續受低層西南風影響,風切變因而強烈,93W 大部分的對流切離至其西面,部分更進入了南海預料 93W 稍後的北移將令其移離高風切區,有利其增強
