TC Naming 氣旋命名
MORAKOT was contributed by Thailand, meaning emerald in English. This name was last used in 2003.
莫拉克一名由泰國提供，意思為綠寶石。這名稱曾於 2003 年使用。
Movement Analysis 路徑分析
MORAKOT is expected to travel N in the western periphery of the subtropical ridge.
預料莫拉克將沿副熱帶高壓脊之西面向北移動。
Intensity Analysis 強度分析
Current T-number: T3.5/3.5/S0.0/24 HRS
MORAKOT should make landfall in Fujian later today as a severe tropical storm. Weakening follows once MORAKOT touches land again.
現時的 T 號碼: T3.5/3.5/S0.0/24 HRS
莫拉克將以強烈熱帶風暴強度在今日稍後於福建登陸，登陸後它將繼續減弱。

莫拉克一名由泰國提供，意思為綠寶石。這名稱曾於 2003 年使用。
Movement Analysis 路徑分析
MORAKOT is expected to travel WNW towards Taiwan. Afterwards it should assume an increasingly northward track as it travels in the southwestern (turning to western) periphery of the subtropical ridge.

莫拉克一名由泰國提供，意思為綠寶石。這名稱曾於 2003 年使用。
Movement Analysis 路徑分析
MORAKOT is expected to travel WNW under the influence of the subtropical ridge north of the system. It should gradually turn NW as it approaches the southwestern periphery of the ridge.
Current T-number: T4.5/4.5/D0.5/24 HRS
MORAKOT has been moving faster than expected, which will shorten the time available for intensification. Rapid weakening is expected after landfall.
現時的 T 號碼: T4.5/4.5/D0.5/24 HRS
由於莫拉克移動速度比預期快，它可以增強的時間將大幅縮短。莫拉克登陸後將快速減弱。
Effects on Hong Kong 對香港的影響
MORAKOT's subsidence is expected to bring very hot and hazy weather to Hong Kong this weekend.
莫拉克的下沉氣流將於本週末為香港帶來酷熱有煙霞的天氣。

MORAKOT was contributed by Thailand, meaning emerald in English.
莫拉克一名由泰國提供，意思為綠寶石。
Movement Analysis 路徑分析
The subtropical ridge is expected to extend westward above MORAKOT and thus the storm will travel W/WNW towards northern Taiwan. Upon landfall in China it might have a chance of interacting with GONI, provided that the latter has not dissipated inland by then.
Current T-number: T4.0/4.0/D1.5/24 HRS
MORAKOT intensified rapidly in the past 24 hours. Sea surface temperatures are quite favourable and vertical wind shear remains moderate in the seas near the Ryukyu Islands. Intensification at climatological rate or above is expected until landfall.
現時的 T 號碼: T4.0/4.0/D1.5/24 HRS
莫拉克於過去 24 小時迅速增強。由於莫拉克附近水溫頗高，而垂直風切變亦於中等水平，預料莫拉克將可於登陸前以氣候平均值速度或更快增強。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
莫拉克於未來的 72 小時將不會對香港構成任何影響。

Tropical disturbance 98W quickly consolidated into a tropical depression (09W) earlier today, and is now a tropical storm named MORAKOT by the JMA. At 14 HKT, MORAKOT was centred about 900 km (490 NM) ESE of Okinawa.
MORAKOT was contributed by Thailand, meaning emerald in English.
莫拉克一名由泰國提供，意思為綠寶石。
Movement Analysis 路徑分析
MORAKOT is seen travelling north slowly due to the weak dominance of the ridge east of it over the western high pressure area located north of Taiwan (i.e. it is now in a pressure col). It is expected that after the passage of the trough near Japan, the eastern ridge will extend westward and MORAKOT will thus travel WNW towards the Ryukyu Islands. Upon landfall in China it might have a chance of interacting with GONI, provided that the latter has not dissipated inland by then.
Current T-number: T2.5/2.5/INT OBS
Sea surface temperatures are quite favourable and vertical wind shear is not expected to strengthen in the seas near the Ryukyu Islands. Intensification at climatological rate is expected until landfall.
現時的 T 號碼: T2.5/2.5/INT OBS
莫拉克附近水溫頗高，而垂直風切變亦預計不會大幅提升。預料莫拉克將可於登陸前以氣候平均值速度增強。
