MAKA remained very weak. At 20 HKT, MAKA was centred about 550 km (300 NM) SE of Wake Island.
MAKA 強度仍然偏弱。在 20 HKT,MAKA 集結在威克島東南約 550 公里 (300 海里)。
TC Naming 氣旋命名
MAKA is the 7th name in the third column of the central Pacific tropical cyclone name list.
MAKA 為中太平洋熱帶氣旋名稱列表中第三欄第 7 個名字。
Movement Analysis 路徑分析
MAKA is expected to travel west in the southern periphery of the subtropical ridge..
預料 MAKA 將沿副熱帶高壓脊南部向西移動。
Intensity Analysis 強度分析
Current T-number: T1.5/2.0/W0.5/24 HRS
MAKA weakened today as a result of rather high vertical wind shear and low upper-level divergence. MAKA is expected to remain weak in this rather unfavourable environment.
現時的 T 號碼: T1.5/2.0/W0.5/24 HRS
受頗高風切和偏低輻散的影響,MAKA 減弱為熱帶低氣壓。預料在不佳的環境中 MAKA 的強度將維持偏弱。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
MAKA 於未來的 72 小時將不會對香港構成任何影響。

MAKA's convections were sheared away and the low-level circulation centre became exposed. At 14 HKT, MAKA was centred about 710 km (380 NM) ESE of Wake Island.
MAKA 的對流切離其中心,低層環流中心呈外露狀態。在 14 HKT,MAKA 集結在威克島東南偏東約 710 公里 (380 海里)。
TC Naming 氣旋命名
MAKA is the 7th name in the third column of the central Pacific tropical cyclone name list. The Chinese name of the storm will have to be decided if JMA later upgrades the system into tropical storm status.
MAKA 為中太平洋熱帶氣旋名稱列表中第三欄第 7 個名字。如日本氣象廳升格 MAKA 為熱帶風暴,其中文名稱將會於稍後決定。
Movement Analysis 路徑分析
As the ridge north of MAKA extends, it is now expected that the storm will travel W turning gradually to a WNW motion as the ridge weakens later.
由於在 MAKA 北面的脊場加強,預料 MAKA 將向偏西移動,稍後隨著脊場減弱而令向北分量逐漸增加。
Intensity Analysis 強度分析
Current T-number: T2.0/3.0/W1.0/24 HRS
MAKA travelled to a region of high vertical wind shear last night and most of the convections were sheared away from the low-level circulation centre. The shear has weakened and MAKA is expected to maintain strength or intensify slightly in the next 72 hours.
現時的 T 號碼: T2.0/3.0/W1.0/24 HRS
MAKA 昨晚移至高垂直風切變地區,大部分對流切離中心。現該區的垂直風切變稍為減弱,預料 MAKA 將於未來 72 小時維持強度或稍為增強。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
MAKA 於未來的 72 小時將不會對香港構成任何影響。

MAKA has intensified into a tropical storm. At 14 HKT, MAKA was centred about 860 km (470 NM) ESE of Wake Island.
MAKA 已增強為熱帶風暴。在 14 HKT,MAKA 集結在威克島東南偏東約 860 公里 (470 海里)。
TC Naming 氣旋命名
MAKA is the 7th name in the third column of the central Pacific tropical cyclone name list. The Chinese name of the storm will have to be decided if JMA later upgrades the system into tropical storm status.
MAKA 為中太平洋熱帶氣旋名稱列表中第三欄第 7 個名字。如日本氣象廳升格 MAKA 為熱帶風暴,其中文名稱將會於稍後決定。
Movement Analysis 路徑分析
The NNE-SSW oriented ridge E of MAKA is expected to guide it northwards, possibly with some eastward component. As the ridge extends west at higher latitudes, westward component in MAKA's track is expected to increase later on.
在 MAKA 東面東北偏北-西南偏南向的高壓脊將帶領 MAKA 向北移動,且帶有一些向東分量。隨著副熱帶高壓脊於高緯度西伸,MAKA 將有望於到達較高緯度時轉回偏西的移動方向。
Intensity Analysis 強度分析
Current T-number: T3.0/3.0/D1.0/24 HRS
Sea surface temperatures are favourable and wind shear is moderate at the moment. MAKA is expected to strengthen gradually.
現時的 T 號碼: T3.0/3.0/D1.0/24 HRS
MAKA 附近海溫偏高,垂直風切變暫不強烈。預料在大致適中的環境下 MAKA 將逐漸增強。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
MAKA 於未來的 72 小時將不會對香港構成任何影響。

Probabilities of TC Signals from HKO 香港天文台 (已) 發出 / 取消熱帶氣旋警告信號的機率
MAKA was formed in the central Pacific Ocean earlier this week. It weakened into a low pressure area and crossed the international date line in the middle of this week. Now MAKA has picked up strength and re-intensified into a tropical depression. At 14 HKT, MAKA was centred about 950 km (510 NM) SE of Wake Island.
MAKA is the 7th name in the third column of the central Pacific tropical cyclone name list. The Chinese name of the storm will have to be decided if JMA later upgrades the system into tropical storm status.
MAKA 為中太平洋熱帶氣旋名稱列表中第三欄第 7 個名字。如日本氣象廳升格 MAKA 為熱帶風暴,其中文名稱將會於稍後決定。
Movement Analysis 路徑分析
The ridge E/SE of MAKA is expected to provide northward component to MAKA's track in the next 48 hours. As the ridge extends west at higher latitudes, westward component in MAKA's track is expected to increase later on.
在 MAKA 東/東南面的高壓脊將帶領 MAKA 於未來 48 小時逐漸轉向北或西北偏北移動。隨著副熱帶高壓脊於高緯度西伸,MAKA 將有望於預測後期轉回偏西的移動方向。
Intensity Analysis 強度分析
Current T-number: T2.0/2.0/INT OBS
Sea surface temperatures are favourable and wind shear is moderate at the moment. MAKA is expected to strengthen in rather good ambient environments in the next 72 hours.
現時的 T 號碼: T2.0/2.0/INT OBS
MAKA 附近海溫偏高,垂直風切變暫不強烈。預料在大致適中的環境下 MAKA 將於未來 72 小時逐漸增強。
