SARIKA made landfall near Shantou this morning and has weakened since then. Its lower-level circulation centre could not be found in the imagery at 20 HKT. At 14 HKT, SARIKA was centred about 460 km (250 NM) NE of Hong Kong. The Standby Signal was cancelled at 07:15 HKT today.
SARIKA is the 113th name in the tropical cyclone name list. It was contributed by Cambodia, with the meaning of a singing bird. This name was last used in 2004.
05W has intensified into a tropical storm, and was named SARIKA. It has also accelerated towards the NNW in the past 24 hours. At 20 HKT, SARIKA was centred about 310 km (170 NM) ESE of Hong Kong. The Standby Signal was issued at 09:40 HKT today.
SARIKA is the 113th name in the tropical cyclone name list. It was contributed by Cambodia, with the meaning of a singing bird. This name was last used in 2004.
SARIKA has been moving faster than expected. The Pacific subtropical ridge has retreated slightly, and SARIKA is now situated in its western periphery. A generally northward track is likely until landfall.
莎莉嘉比預期移動快。太平洋副熱帶高壓脊稍為東退，而莎莉嘉現處於其西面。預料莎莉嘉將北行直至登陸。

Current T-number: T1.5/2.0/S0.0/24 HRS
SARIKA's low-level circulation centre became exposed earlier today, and regions of strong/gale force winds are confined to the eastern semicircle. SARIKA is expected to maintain its current intensity until landfall, after which rapid weakening follows.
現時的 T 號碼: T1.5/2.0/S0.0/24 HRS
莎莉嘉的低層環流中心今天較早時開始完全外露，其強風及烈風範圍主要在東半圓。預料莎莉嘉將維持強度直至登陸，其後快速減弱。
Effects on
Hong Kong 對香港的影響
Squally showers are expected tomorrow and on Sunday due to rainbands associated with SARIKA and the southwesterly airstream induced by the storm.
莎莉嘉的雨帶及由它引進的西南氣流將於未來兩天為香港帶來狂風驟雨。

Tropical disturbance 92W near the Philippines intensified into tropical depression 05W this morning. At 20 HKT, 05W was centred about 810 km (440 NM) SE of Hong Kong.
05W is currently situated in the southwestern periphery of the subtropical ridge anchored in northwestern Pacific Ocean, which is contributing to its current NW movement. As 05W moves to higher latitudes, it will reach the western periphery of the ridge and will gradually turn poleward, which a chance of recurving after landfall.
Current T-number: T1.5/1.5/INT OBS
05W's convections appear loose compared to earlier today, while the southwest monsoon is providing the storm with moisture in its southern periphery. The storm is situated in warm seas (about 30 degrees) with low to moderate vertical wind shear. It is expected that 05W will intensify slightly before landfall, and weaken rapidly afterwards.
