DOKSURI made landfall in Zhuhai near dawn and has weakened into a tropical depression. At 14 HKT, DOKSURI was centred about 380 km (210 NM) W of Hong Kong. All tropical cyclone signals were cancelled at 08:15 HKT.
DOKSURI is the 137th name in the tropical cyclone name list. It was contributed by South Korea, meaning a bird of prey. This name replaces NABI which caused significant damage to Japan in 2005.
DOKSURI will soon be at its closest point of approach to Hong Kong. At 23 HKT, DOKSURI was centred about 100 km (55 NM) SSE of Hong Kong. The No. 8 NE Gale or Storm Signal was issued at 23:05 HKT.

DOKSURI will be closest to Hong Kong in the next few hours. Gale force winds are expected in the territory overnight, coming in from the east veering to southeast in the next 12 hours. There will also be squally showers. Winds will subside tomorrow morning as DOKSURI makes landfall and weakens.
DOKSURI is moving WNW quickly in northern South China Sea. At 14 HKT, DOKSURI was centred about 280 km (150 NM) ESE of Hong Kong. The Strong Wind Signal will be issued soon.

According to the present track, DOKSURI will be closest to Hong Kong near midnight tonight. North to north-easterly winds are expected to strengthen tonight with squally showers. There is a chance of observing cyclonic winds at closest point of approach if the storm moves close enough to the territory.
DOKSURI is crossing the Luzon Strait. At 20 HKT, DOKSURI was centred about 740 km (400 NM) ESE of Hong Kong. The Standby Signal no. 1 was issued at 21:40 HKT.
DOKSURI is the 137th name in the tropical cyclone name list. It was contributed by South Korea, meaning a bird of prey. This name replaces NABI which caused significant damage to Japan in 2005.
The subtropical ridge has extended westward over the past 24 hours. DOKSURI is expected to travel WNW steadily along its southwestern periphery towards the Pearl River Estuary.

DOKSURI's convections continued to be sheared to the southwest, but the storm has expanded in size and is acquiring spiraling characteristics. The storm is expected to strengthen slightly as it travels in the warm South China Sea with moderate shear. Rapid weakening follows as DOKSURI makes landfall at around t+36.

Subsidence associated with DOKSURI will continue to bring hazy and very hot weather to Hong Kong on Friday. According to the present forecast track, winds in Hong Kong will start to strengthen on Friday night, coming in from the north. Squally showers are also expected. There is a chance of observing cyclonic winds on Saturday if the storm moves close enough to the territory.
DOKSURI is the 137th name in the tropical cyclone name list. It was contributed by South Korea, meaning a bird of prey. This name replaces NABI which caused significant damage to Japan in 2005.
Instability of the circulation and the existence of multiple vortices created significant difficulty in locating DOKSURI's centre. The storm is still situated in the southwestern periphery of the subtropical ridge and is expected to move WNW, but a relocation is possible tomorrow as the system evolves.
Current T-number: T2.5/2.5/S0.0/24 HRS
Most of the convections are sheared to the west, leaving the circulation centre exposed. The storm should gain some strength in warm seas but the rate will be limited as it moves close to northern Luzon.

Subsidence associated with DOKSURI may result in hazy and very hot weather on Thursday and Friday. According to the present forecast track, winds in Hong Kong will start to strengthen on Friday night, coming in from the north. Squally showers are also expected.
A tropical disturbance east of the Philippines intensified into a tropical depression earlier today, and further into a tropical storm tonight. It was given the number 07W by the JTWC and named DOKSURI by the JMA. At 20 HKT, DOKSURI was centred about 1030 km (550 NM) E of Manila.
DOKSURI is the 137th name in the tropical cyclone name list. It was contributed by South Korea, meaning a bird of prey. This name replaces NABI which caused significant damage to Japan in 2005.
DOKSURI is currently situated in the southwestern periphery of a broad subtropical ridge, and hence is expected to move NW initially. The ridge is expected to extend westward in the next few days that may cause DOKSURI to move in a more equatorward direction.
Current T-number: T2.5/2.5/INT OBS
DOKSURI is slowly organizing its convections. In favourable shear and sea temperature conditions the storm is expected to strengthen steadily before entering the South China Sea. Increased shear and proximity to land in the latter stages may inhibit DOKSURI's intensification.

杜蘇芮正慢慢組織其環流。在良好海溫和低風切情況下，預料杜蘇芮將於進入南海前穩步增強。進入南海後，風切或會提升，且風暴較為靠近陸地，強度將受限制。
