MUJIGAE made landfall at northern Vietnam this morning. At 14 HKT, MUJIGAE was centred about 140 km (75 NM) SSW of Hanoi.
彩虹今早於越南北部登陸。在 14 HKT,彩虹集結在河內西南偏南約 140 公里 (75 海里)。
TC Naming 氣旋命名
MUJIGAE is the 87th name in the tropical cyclone name list. This name was contributed by North Korea, which means rainbow. MUJIGAE is used for the first time, replacing the name MAEMI at the same location in the list. MAEMI was an extremely intense cyclone and devastated parts of South Korea in 2003.
MUJIGAE sped across northern South China Sea and made landfall in northern Hainan early today. It is now about to make landfall again in Vietnam. At 20 HKT, MUJIGAE was centred about 200 km (110 NM) SE of Hanoi.

MUJIGAE is expected to travel W to WNW along the south to southwestern periphery of the subtropical ridge.
預料彩虹將沿副熱帶高壓脊南至西南部向西或西北偏西移動。
Intensity Analysis 強度分析
Current T-number: T2.5/2.5/D0.5/24 HRS
MUJIGAE should remain as a tropical storm in the rest of its journey across the South China Sea and Gulf of Tonkin. It will weaken rapidly after it makes landfall in Vietnam.
現時的 T 號碼: T2.5/2.5/D0.5/24 HRS
預料彩虹將於登陸越南前維持熱帶風暴強度,其後將急速減弱。
Effects on Hong Kong 對香港的影響
MUJIGAE has passed its closest approach to Hong Kong. Winds from the east will still be strong for some time, but will subside gradually tomorrow.
14W has intensified into a tropical storm, and was named MUJIGAE earlier by the JMA. At 13 HKT, MUJIGAE was centred about 330 km (180 NM) S of Hong Kong.

MUJIGAE travelled at a rather high speed last night as it consolidated. It is expected to travel W to WNW along the south to southwestern periphery of the subtropical ridge.
彩虹昨夜逐漸整固,移動速度較快。預料彩虹將沿副熱帶高壓脊南至西南部向西或西北偏西移動。
Intensity Analysis 強度分析
Current T-number: T2.5/2.5/D0.5/18 HRS
Vertical wind shear is increasing in the South China Sea and MUJIGAE's low-level circulation centre is partially exposed. MUJIGAE should remain as a tropical storm in the rest of its journey across the South China Sea and Gulf of Tonkin. It will weaken rapidly after it makes landfall in Vietnam.
現時的 T 號碼: T2.5/2.5/D0.5/18 HRS 南海的垂直風切變稍為增強,而彩虹的低層環流中心呈部分外露狀態。預料彩虹將於登陸越南前維持熱帶風暴強度,其後將急速減弱。
Effects on Hong Kong 對香港的影響
MUJIGAE is expected to be closest to Hong Kong in the next few hours, passing some 300 km (160 NM) south of the Observatory. Winds will strengthen from the northeast, turning into southeast later tonight.
Tropical disturbance 90W consolidated quickly and intensified into a tropical depression (14W) earlier today. At 20 HKT, 14W was centred about 560 km (300 NM) SSE of Hong Kong.
14W is expected to move W to WNW in the next 3 days under the influence of an anticyclone in central China.
受到華中的反氣旋影響,預料 14W 將於未來三天向西或西北偏西移動。
Intensity Analysis 強度分析
Current T-number: T2.0/2.0/INT OBS
Vertical wind shear is increasing in the South China Sea while both divergence and convergence are still developing near the storm. Sea surface temperatures are favourable. It is therefore expected that 14W should be able to intensify into a tropical storm in the near future before touching Hainan Island.
現時的 T 號碼: T2.0/2.0/INT OBS 南海的垂直風切變稍為增強,水溫頗高,而 14W 附近的低層輻合和高層輻散則正在發展。預料 14W 將可於登陸前增強至熱帶風暴強度。
Effects on Hong Kong 對香港的影響
According to the present track, parts of Hong Kong might experience strong winds on Thursday and Friday with winds turning from northeast to southeast.
按照目前預測路徑,香港部分地方可能於本週四至週五吹強風,風向由東北逐漸轉向東南。
