MOLAVE is passing to the north of HK. At 02 HKT, MOLAVE was centred about 35 km (20 NM) NNE of the HK Observatory.

莫拉菲正於香港北部掠過。在 02 HKT,莫拉菲集結在香港天文台東北偏北約 35 公里 (20 海里)。

TC Naming 氣旋命名

The name MOLAVE was contributed by the Philippines, which is a popular hard wood used in furniture. MOLAVE replaced the name IMBUDO at the same position due to the latter cyclone's destructive power and was first used as a name for tropical cyclones.

莫拉菲一名由菲律賓提供,為一種常用於製造傢俬的硬木。該名字為首次使用,代替曾造成重大破壞的熱帶氣旋伊布都。

Movement Analysis 路徑分析

The western extension of the subtropical ridge has lifted northwards, but steering remains primarily to the W/WNW. MOLAVE is expected to move W to WNW in the next 24 hours over Guangdong landmass.

副熱帶高壓脊西沿位置向北移,但南海北部駛流還是以向西至西北偏西為主。預料莫拉菲將向西或西北偏西移動,移入廣東中部。

Intensity Analysis 強度分析

Rapid weakening will follow after landfall.

現時的 T 號碼: T4.5/4.5/D0.5/06 HRS
預料莫拉菲將於登陸後急速減弱

Effects on Hong Kong 對香港的影響

Rain and winds reaching storm force or above will affect HK in the coming hours. Wind direction is likely to change in a counterclockwise manner from northwest to southwest in the early hours of tomorrow. If MOLAVE passes sufficiently close to HK, cyclonic winds may be observed. Low-lying areas may experience flooding.

MOLAVE is expected to be closest to Hong Kong at about 3 am to 6 am on Sunday.

預料未來數小時本地風速將達暴風程度或以上。風向很可能於黎明附近由西北逆時針轉向西南。如莫拉菲非常接近香港,本地將有可能吹旋風。低窪地區可能會有海水倒灌。

預料莫拉菲將於星期日上午約 3 至 6 時最接近香港。

莫拉菲一名由菲律賓提供,為一種常用於製造傢俬的硬木。該名字為首次使用,代替曾造成重大破壞的熱帶氣旋伊布都。

Movement Analysis 路徑分析

The western extension of the subtropical ridge has lifted northwards, but steering remains primarily to the W/WNW. MOLAVE is expected to move W to WNW in the next 24 hours towards central Guangdong coast.

副熱帶高壓脊西沿位置向北移,但南海北部駛流還是以向西至西北偏西為主。預料莫拉菲將向西或西北偏西移動,趨向廣東中部沿岸。

Intensity Analysis 強度分析

Current T-number: T4.0/4.0/D0.0/15 HRS
Sufficient sea surface temperatures, good outflow and moderate shear will allow MOLAVE to maintain strength until landfall. Rapid weakening will follow once landfall is encountered.

現時的 T 號碼: T4.0/4.0/D0.0/15 HRS
受較高海水溫度,良好輻散和中等的垂直風切變影響,預料莫拉菲將可維持強度直至登陸登陸後莫拉菲將急速減弱

Effects on Hong Kong 對香港的影響

Very hot weather was encountered in most parts of HK early today. The weather will deteriorate significantly tonight, with winds reaching gale force or above and rain intensifying. Wind change pattern is still uncertain, but a landfall to the east of HK is becoming slightly more favourable. If MOLAVE passes sufficiently close to HK, cyclonic winds may be observed.

酷熱和有煙霞的天氣於今日初期影響香港。預料今晚天氣將急速轉壞,風勢和雨勢將大幅增強,風速將達烈風程度或以上。由於登陸點仍未確定 (但比較可能在香港以東登陸),風向的轉變仍未能完全掌握;如莫拉菲非常接近香港,本地將有可能吹旋風。

MOLAVE moved W to WNW in the past 12 hours, intensifying slightly in the meantime. At 11 HKT, MOLAVE was centred about 380 km (200 NM) ESE of Hong Kong.

莫拉菲於過去 12 小時向西至西北偏西移動,並稍為增強。在 11 HKT,莫拉菲集結在香港東南偏東約 380 公里 (200 海里)。

TC Naming 氣旋命名

The name MOLAVE was contributed by the Philippines, which is a popular hard wood used in furniture. MOLAVE replaced the name IMBUDO at the same position due to the latter cyclone's destructive power and was first used as a name for tropical cyclones.

莫拉菲一名由菲律賓提供,為一種常用於製造傢俬的硬木。該名字為首次使用,代替曾造成重大破壞的熱帶氣旋伊布都。

Movement Analysis 路徑分析

Affected by the subtropical ridge north of the system, MOLAVE is expected to move W to WNW in the next 48 hours towards central Guangdong coast. Track speed is expected to remain fast at about 22 km/h until landfall as strong steering exists.

受副熱帶高壓脊的影響,預料莫拉菲將繼續向西至西北偏西移動,趨向廣東中部沿岸。由於駛流明顯,預料莫拉菲於登陸前移動的速度稍高,約為每小時 22 公里。

Intensity Analysis 強度分析

Current T-number: T4.0/4.0/D0.0/15 HRS
Sufficient sea surface temperatures, good outflow and moderate shear will allow MOLAVE to maintain strength until landfall. Rapid weakening will follow once landfall is encountered.

現時的 T 號碼: T4.0/4.0/D0.0/15 HRS
受較高海水溫度,良好輻散和中等的垂直風切變影響,預料莫拉菲將可維持強度直至登陸登陸後莫拉菲將急速減弱

Effects on Hong Kong 對香港的影響

According to the present forecast track, hot and hazy weather in Hong Kong is expected early today. The weather will deteriorate significantly tonight, with winds becoming much stronger and rain intensifying. Wind change pattern is still uncertain as chances for landfalling east and west of HK are about equal. If MOLAVE passes sufficiently close to HK, cyclonic winds may be observed.

按照目前預測路徑,預料炎熱和有煙霞的天氣將於今日初期影響香港;今晚天氣將急速轉壞,風勢和雨勢將大幅增強。由於登陸點仍未確定,風向的轉變仍未能完全掌握;如莫拉菲非常接近香港,本地將有可能吹旋風。

MOLAVE developed an eye visible on satellite imagery, and in 1-minute standard MOLAVE is deemed to have intensified into a typhoon. At 20 HKT, MOLAVE was centred about 760 km (410 NM) ESE of Hong Kong.

莫拉菲發展出風眼,於一分鐘平均風速機制下本站將其升格為颱風。在 20 HKT,莫拉菲集結在香港東南偏東約 760 公里 (410 海里)。

TC Naming 氣旋命名

莫拉菲一名由菲律賓提供,為一種常用於製造傢俬的硬木。該名字為首次使用,代替曾造成重大破壞的熱帶氣旋伊布都。

Movement Analysis 路徑分析

MOLAVE is seen to move NW in the past 6 hours, tracking to the northern part of the Luzon Strait. It is expected that the subtropical ridge will allow MOLAVE to turn WNW soon. Track speed is expected to remain fast at about 22 km/h until landfall as strong steering exists.

莫拉菲於過去 6 小時繼續向西北移動,現在於呂宋海峽北部。受副熱帶高壓脊的影響,預料莫拉菲將轉向西北偏西移動。由於駛流明顯,預料莫拉菲於登陸前移動的速度稍高,約為每小時 22 公里。

Intensity Analysis 強度分析

Current T-number: T4.0/4.0/D0.5/06 HRS
A banding eye has developed, but land effect is distorting the structure in its vicinity somewhat. Wind shear in the South China Sea remains low. It is expected that good divergence and favourable sea temperatures will allow MOLAVE to intensify slightly in the next 12 hours before it starts to weaken as drier air and higher shear set in.

現時的 T 號碼: T4.0/4.0/D0.5/06 HRS
莫拉菲發展出雲捲風眼,但由於地形影響其形狀有待改善南海的垂直風切變亦維持在偏低水平由於輻散和海溫仍佳,預料莫拉菲將可於未來 12 小時增強;稍後由於受到較強垂直風切變和較乾空氣影響而開始減弱

Effects on Hong Kong 對香港的影響

According to the present forecast track, hot and hazy weather in Hong Kong is expected today and early tomorrow. Northerly winds should be observed starting later tomorrow; the weather will deteriorate by then. Exact wind shift sequence and strength are still highly dependent on where MOLAVE starts its WNW turn, but by now it is likely that strong force winds will affect the territory on Sunday.

按照目前預測路徑,預料炎熱和有煙霞的天氣將於今天和明天初期影響香港;明日稍後將轉吹北風,天氣將於晚間轉壞。雖然風速和風向的轉變仍未能完全掌握,但根據現時資料香港將可能於星期日吹強風。

07W intensified further into a severe tropical storm, and was named MOLAVE by the JMA. At 14 HKT, MOLAVE was centred about 920 km (500 NM) ESE of Hong Kong.

07W 繼續增強為強烈熱帶風暴,並被日本氣象廳命名為莫拉菲。在 14 HKT,莫拉菲集結在香港東南偏東約 920 公里 (500 海里)。

TC Naming 氣旋命名

莫拉菲一名由菲律賓提供,為一種常用於製造傢俬的硬木。該名字為首次使用,代替曾造成重大破壞的熱帶氣旋伊布都。

Movement Analysis 路徑分析

The subtropical ridge has weakened slightly, but is still covering southeastern China and parts of Taiwan.. It is expected that the ridge will allow MOLAVE to turn WNW soon. Track speed is expected to remain fast at about 22 km/h as strong steering exists.

副熱帶高壓脊於昨晚稍為減弱,但仍覆蓋中國東南部和部分台灣地區。隨著莫拉菲移向約北緯 20 度,它將受副高西延影響而轉向西北偏西移動。由於駛流明顯,預料莫拉菲前進的速度稍高,約為每小時 22 公里。

Intensity Analysis 強度分析

Current T-number: T3.5/3.5/D1.0/24 HRS
Convective clouds continue to burst around the centre, and from visible imagery MOLAVE is developing a banding eye. Wind shear has increased slightly in the South China Sea. It is expected that good divergence and favourable sea temperatures will allow MOLAVE to intensify further, possibly maturing as a typhoon, before it starts to weaken as land effect and higher shear set in.

現時的 T 號碼: T3.5/3.5/D1.0/24 HRS
莫拉菲附近對流爆發持續,從可見光衛星雲圖可見該系統正嘗試建立雲捲風眼南海的垂直風切變於過去 24 小時稍為增強由於輻散和海溫仍佳,預料莫拉菲將可繼續增強,或可成為一股颱風;稍後由於受到較強垂直風切變和接近陸地影響而開始減弱

According to the present forecast track, hot and hazy weather in Hong Kong is expected today and early tomorrow. Northerly winds should be observed starting later tomorrow; the weather will deteriorate by then. Exact wind shift sequence and strength are still highly dependent on where MOLAVE starts its WNW turn, but by now it is quite likely that strong force winds will affect the territory on Sunday.

07W intensified into a tropical storm this morning. At 14 HKT, 07W was centred about 530 km (280 NM) ENE of Manila.

07W 於今晨增強為熱帶風暴。在 14 HKT,07W 集結在馬尼拉東北偏東約 530 公里 (280 海里)。

Movement Analysis 路徑分析

The subtropical ridge is firmly established in southeastern China. It is expected that the ridge will allow 07W to turn WNW after reaching higher latitudes due to the ridge's dominance there.

於華南的脊場現已建立。預料副熱帶高壓脊將繼續覆蓋華南沿岸,致使 07W 到達較高緯度時轉向西北偏西移動。

Intensity Analysis 強度分析

Current T-number: T2.5/2.5/D0.5/18 HRS
Wind shear has increased to the south of 07W. The storm tried to wrap the circulation cloud bands into its centre but most attempts ended in failure. However, it seems that 07W is now able to slowly wrap its cloud bands in the southeastern quadrant. Sea temperatures and divergence remain good, but wind shear may increase later as 07W enters the South China Sea. Gradual strengthening is thus expected until t+48 when wind shear and proximity to land become inhibiting factors then.

現時的 T 號碼: T2.5/2.5/D0.5/18 HRS
07W 以南的垂直風切變明顯增強該系統曾多次嘗試把對流捲入中心,但未見成果最近的衛星圖像顯示 07W 開始成功捲入東南面的對流07W 的輻散和附近海溫仍佳,但預料當 07W 進入南海時風切將稍為增強在此情況下,預料 07W 將於未來 48 小時逐漸發展,其後由於風切變增加和靠近陸地而減弱

Effects on Hong Kong 對香港的影響

According to the present forecast track, hot and hazy weather in Hong Kong is expected in the next two days, and northerly squalls and rain might affect Hong Kong in the first half of the coming Sunday.

按照目前預測路徑,預料炎熱和有煙霞的天氣將於未來兩日影響香港;星期日前半部香港可能受偏北狂風影響並有雨。

The subtropical ridge is seen north and east of 07W, which contributes to its present NW movement. It is expected that the ridge will strengthen further and 07W will turn to a WNW direction after reaching higher latitudes due to the ridge's dominance there.

副熱帶高壓脊正處於 07W 的北面和東面,其東南氣流正令 07W 向西北移動。預料副高將於本週後期繼續西伸,覆蓋華南沿岸,致使 07W 到達較高緯度時轉向西北偏西移動。

Intensity Analysis 強度分析

Current T-number: T2.0/2.0/INT OBS
Favourable divergence, light wind shear and good sea surface temperatures will cause 07W to strengthen at about climatological rate in the next 48 hours. Proximity to land and the expected higher shear when 07W enters South China Sea might cause intensification to cease later, but this is effect is rather uncertain at this moment.

現時的 T 號碼: T2.0/2.0/INT OBS
良好的輻散,較低的垂直風切變和頗高的海溫將於未來 48 小時 07W 以接近氣候平均值速度增強。預計 07W 將於 48 小時後稍為靠近陸地,而南海的垂直風切變亦有可能增強,兩者皆會令增強速度放緩但現在為止此情景出現的可能性仍未算明朗

Effects on Hong Kong 對香港的影響
