EWINIAR is the ninth name in the tropical cyclone name list. It was contributed by Micronesia, and is the storm God of Chuuk. This name was used in 2000 and 2006.
EWINIAR moved erratically as it interacted with an upper low. The storm is expected to accelerate northeastward rapidly in the northwestern periphery of the subtropical ridge.
受高空低壓影響，艾雲尼移動路徑較不規則。預料隨後艾雲尼將受副高帶動，沿其西北部向東北加速移動。

Current T-number: T3.5/3.5/S0.0/24 HRS
EWINIAR's intensity did not change much in the past 24 hours. However, it is expected to weaken at lower sea temperatures and extratropical transition should take place near t+48.
現時的 T 號碼: T3.5/3.5/S0.0/24 HRS
艾雲尼的強度於過去 24 小時無甚改變，但預料將會於較冷海水中減弱。艾雲尼將於約 48 小時後轉化為溫帶氣旋。

EWINIAR is the ninth name in the tropical cyclone name list. It was contributed by Micronesia, and is the storm God of Chuuk. This name was used in 2000 and 2006.
EWINIAR is expected to decelerate in the next 12 hours as it interacts with an upper low. After that, the storm will recurve sharply to the NE into the westerlies.
艾雲尼將於未來 12 小時減慢並與附近一個高空低壓相互影響，隨後急速轉向東北移動，逐漸併入西風帶。

Current T-number: T3.5/3.5/D0.5/24 HRS
EWINIAR's convections appear loose but well-defined. The storm is expected to intensify slightly under improved divergence, but will weaken once it reaches cooler seas. Extratropical transition will take place in three days' time.
現時的 T 號碼: T3.5/3.5/D0.5/24 HRS
艾雲尼的對流較為鬆散，但旋捲性明顯。預料在良好輻散環境下艾雲尼將稍為增強，至到達較冷海域時減弱。艾雲尼將於三天內轉化為溫帶氣旋。

EWINIAR has intensified into a severe tropical storm. At 08 HKT, EWINIAR was centred about 60 km (30 NM) N of Iwo Jima.
艾雲尼已增強為強烈熱帶風暴。在上午 8 時，艾雲尼集結在硫磺島以北約 60 公里 (30 海里)。

Naming 氣旋命名
EWINIAR is the ninth name in the tropical cyclone name list. It was contributed by Micronesia, and is the storm God of Chuuk. This name was used in 2000 and 2006.
EWINIAR is moving eastward due to the low-latitude extension of the subtropical ridge. As the storm approaches the western end of the ridge at its latitude, it is expected to turn N or NNW. EWINIAR should recurve along the ridge's northwestern periphery, but before that storm speed is forecast to drop sharply as EWINIAR interacts with an upper low developed off southern Japan, as indicated by numerical models.
Current T-number: T3.0/3.0/D0.5/24 HRS
EWINIAR's convections are still sheared, but are now concentrated closer to the low-level circulation centre. EWINIAR will intensify in good conditions and improving divergence associated with the trough, but will weaken once it starts to recurve due to lower sea temperatures. Extratropical transition is expected to take place between t+72 and t+96.
現時的 T 號碼: T3.0/3.0/D0.5/24 HRS
艾雲尼的對流仍然有所切離，但深層對流已經比較靠近其低層環流中心。預料在良好大氣環境及槽前輻散轉好的情況下艾雲尼將會增強，但於較高緯度海溫降低時開始減弱。艾雲尼將於三至四天後轉化為溫帶氣旋。

A tropical disturbance south of Iwo Jima has gradually intensified into tropical storm 19W, and was named EWINIAR. At 02 HKT, EWINIAR was centred about 520 km (280 NM) SSW of Iwo Jima.
EWINIAR is the ninth name in the tropical cyclone name list. It was contributed by Micronesia, and is the storm God of Chuuk. This name was used in 2000 and 2006.
EWINIAR is expected to move N along the western periphery of the subtropical ridge. As the ridge extends westwards south of EWINIAR, there will be some eastward track component. EWINIAR will gradually move to the northwestern periphery of the subtropical ridge where a recurving scenario is expected.
Current T-number: T2.5/2.5/INT OBS
Convections in EWINIAR's western periphery are restricted by Super Typhoon JELAWAT's outflow. However, as EWINIAR moves north, it will be free from such restriction and will enjoy warm seas with low shear. Intensification is thus expected until t+48 to 72.
現時的 T 號碼: T2.5/2.5/INT OBS
超級颱風杰拉華的幅散阻礙艾雲尼西面對流的發展，但隨著艾雲尼北移，它將擺脫此障礙，並預計能於暖海域及低風切的環境下增強直至 48 至 72 小時後。
