TC Naming 氣旋命名
DUJUAN is the 86th name in the tropical cyclone name list. This name was contributed by China and is the Chinese name for azalea. DUJUAN was last used in 2003; the storm associated with this name necessitated the #9 Increasing Gale or Storm Signal in Hong Kong.
DUJUAN will move NE along the northwestern periphery of the subtropical ridge.

DUJUAN turned northeast yesterday. At 14 HKT, DUJUAN was centred about 520 km (280 NM) S of Tokyo.
杜鵑昨日開始轉向東北移動。在 14 HKT，杜鵑集結在東京以南約 520 公里 (280 海里)。

DUJUAN's strength is expected to be stable in the next 24 to 48 hours. Extratropical transition will start between t+12 and t+24.
DUJUAN has slowed down considerably. At 14 HKT, DUJUAN was centred about 930 km (500 NM) SSW of Tokyo.

Intensity Analysis 強度分析
Current T-number: T3.0/3.0/S0.0/24 HRS
DUJUAN failed to intensify in the past 24 hours. Improve in divergence is expected to raise its intensity somewhat, but intensification to typhoon strength is not expected now. Extratropical transition will start two days later.
現時的 T 號碼: T3.0/3.0/S0.0/24 HRS 杜鵑於過去 24 小時未能增強。預計輻散轉好將可令杜鵑的強度有所提升，但未能達颱風強度。杜鵑將於兩天後開始溫帶氣旋轉化。
Effects on Hong Kong 對香港的影響

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
DUJUAN is the 86th name in the tropical cyclone name list. This name was contributed by China and is the Chinese name for azalea. DUJUAN was last used in 2003; the storm associated with this name necessitated the #9 Increasing Gale or Storm Signal in Hong Kong.
Steered by the low-latitude high, DUJUAN moved NE last night. DUJUAN is expected to gradually turn north as the ridge re-orientates and strengthens to the east of it. DUJUAN will pass the ridge axis near t+48 and is then expected to turn northeastwards along the northwestern periphery of the subtropical ridge.
Current T-number: T3.0/3.0/D0.5/24 HRS
Convections are limited in the northeastern periphery of the storm. As DUJUAN is expected to slow down and outflow is expected to improve, DUJUAN should be able to attain typhoon strength in two days' time. Extratropical transition will start three days later.
現時的 T 號碼: T3.0/3.0/D0.5/24 HRS 杜鵑東北面的環流仍然稀少。預計杜鵑的前進速度將會減慢，並將受惠於西風槽前的輻散，使其得以於兩天內增強為颱風。杜鵑將於三天後開始溫帶氣旋轉化。

DUJUAN is the 86th name in the tropical cyclone name list. This name was contributed by China and is the Chinese name for azalea. DUJUAN was last used in 2003; the storm associated with this name necessitated the #9 Increasing Gale or Storm Signal in Hong Kong.
DUJUAN slowed down and turned eastward last night. The ridge north of DUJUAN is weakening rapidly while the low-latitude ridge SE of the storm is strengthening. The combined outcome is that DUJUAN will track northeastward in the next 48 hours. As the ridge later re-orientates and strengthens to the east of DUJUAN, a temporary shift back to northward movement is expected near t+72.
Current T-number: T2.5/2.5/D0.5/18 HRS
Rather strong shear is expected to limit development in the next 24 to 36 hours. Situations will become more favourable with an increase in outflow which should support typhoon status in three days' time.
現時的 T 號碼: T2.5/2.5/D0.5/18 HRS 週邊較強垂直風切變將於未來 24 至 36 小時限制杜鵑的發展。隨著輻散稍後轉好，預料杜鵑仍可於三天內增強為颱風。

The subtropical ridge to the north of 13W is contributing to its westward movement. It is expected that the ridge will weaken and a weakness will develop in the near future, allowing 13W to turn poleward. A high pressure at low latitudes is expected to provide eastward component in 13W's track.
Current T-number: T2.0/2.0/INT OBS
Shear is moderate at where 13W is situated but is increasing on either side. Development is still expected as such environments are not expected to persist.
現時的 T 號碼: T2.0/2.0/INT OBS 13W 附近垂直風切變微弱，但兩邊較遠的地區則較強。由於預料不利環境將不會持續，13W 應該能逐漸增強。
Effects on Hong Kong 對香港的影響
No threat to Hong Kong is expected within the next 72 hours.
13W 於未來的 72 小時將不會對香港構成任何影響。
