Naming 氣旋命名
LIONROCK is the 102nd name in the tropical cyclone name list. It was contributed by Hong Kong and is the name of a peak in the territory. This name replaced TINGTING, which was used in 2004, at the same position.
The interaction between LIONROCK and NAMTHEUN caused LIONROCK to move ESE briefly. Influence from the equatorial ridge is expected to drive LIONROCK northeastward in the next 24 hours. The subtropical ridge will extend after KOMPASU moves to the north and will allow a westerly motion.
Current T-number: T2.5/3.0/W1.0/24 HRS
LIONROCK's low-level circulation centre was again exposed and convections displaced to the southwest. The storm should intensify prior to landfall, after the dissipation of NAMTHEUN.

LIONROCK is now moving eastward and intensified into a severe tropical storm today. At 20 HKT, LIONROCK was centred
about 340 km (180 NM) ESE of Hong Kong. The #1 Standby Signal was cancelled at 19:10 HKT.
LIONROCK is the 102nd name in the tropical cyclone name list. It was contributed by Hong Kong and is the name of a peak in the territory. This name replaced TINGTING, which was used in 2004, at the same position.
The equatorial anticyclone has shifted southward while the high pressure cell in China has moved westward. 09W (which was named NAMTHEUN just now) developed into a tropical cyclone despite situated in an increasingly hostile environment. It is forecast that as LIONROCK absorbs the weaker NAMTHEUN, it will be pushed slightly northeastward together with the steering given by the equatorial anticyclone. An alternative scenario is that LIONROCK may move due east or even ESE (also slowly) as it spins anticlockwise around the common centre of LIONROCK and NAMTHEUN. The amount of latitude LIONROCK gains/loses will be crucial to its final landfall position when the subtropical ridge rebuilds and pushes it NW/WNW.
Current T-number: T3.5/3.5/D0.5/24 HRS
LIONROCK's convection is becoming symmetrical and has tightened today. The storm also seems to be developing an eye visible in microwave imagery. Seas in LIONROCK's vicinity are still favourable for development and typhoon strength is now expected in possibly a day's time.
現時的 T 號碼: T3.5/3.5/D0.5/24 HRS
獅子山的對流變得更為對稱而緊密，並開始嘗試發展風眼，於微波影像可見。該氣旋附近海域仍適合增強；預料獅子山將於約一天內達到颱風強度。

Hong Kong 對香港的影響
Hazy and very hot weather with occasional squally thunderstorms is expected in the next two days. It is also possible for the Observatory to reissue tropical cyclone signals if LIONROCK returns.
07W moved northward and was named LIONROCK. At 20 HKT, LIONROCK was centred
about 290 km (160 NM) SE of Hong Kong. The #1 Standby Signal was issued at 10:35 HKT this morning.
LIONROCK is the 102nd name in the tropical cyclone name list. It was contributed by Hong Kong and is the name of a peak in the territory. This name replaced TINGTING, which was used in 2004, at the same position.
Due to an equatorial anticyclone recognized in steering flow charts, LIONROCK started to track NNE slowly in the past 6 hours. However, the NW force from the Pacific subtropical ridge and W/SW force from the anticyclone in southern China roughly cancel that northeastward force which renders LIONROCK almost motionless in the past 3 hours. Slow movement is expected until t+48, after which the subtropical ridge should extend to propel LIONROCK in a WNW direction. It should also be noted that as 08W (KOMPASU) draws closer to Taiwan, the separation between the two cyclones is reduced and interaction between them is possible. If this happens, LIONROCK's movement will be complicated further.
Current T-number: T3.0/3.0/D0.5/24 HRS
Intensification seems to be impeded by another low pressure area (LPA) east of Taiwan. LIONROCK's convections are concentrated to its western semicircle, though the low-level circulation centre is covered. Intensification is possible given good ambient environments and the LPA dissipating as KOMPASU approaches (though will still be hindered if they are too close and KOMPASU strengthens rapidly). The extent of intensification depends partly on how long LIONROCK stays in water.
現時的 T 號碼: T3.0/3.0/D0.5/24 HRS
受到台灣以東的低壓區之影響，獅子山增強速度緩慢，其對流集中在西半圓，但低層環流中心則已被雲帶覆蓋。隨著圓規靠近，該低壓區將逐漸消散，而獅子山的增強空間亦變大 (除非兩氣旋相距太近且圓規大幅增強)。獅子山的增強幅度某部分取決於其逗留在海面的長短。
Effects on
Hong Kong 對香港的影響
As LIONROCK remains quasi-stationary, hazy weather with occasional squally thunderstorms is expected in the next two days. Winds may strengthen mid-week this week as LIONROCK re-approaches.
07W was relocated early today. The western edge of the subtropical ridge anchored near Japan will steer 07W northwards in the next 48 hours, though the steering is weak and forward speed is expected to be low later. The ridge may re-extend later in the forecast period to induce a more westerly motion.
Current T-number: T2.5/2.5/D0.5/24 HRS
Bursts in convection could be seen near 07W's centre, but the rate of intensification has been low in the past 24 hours. Nevertheless, 07W is expected to pick up strength in the next 48 hours as it continues to travel in warm seas.
Haze will continued to be observed tomorrow. According to the present forecast track, winds in Hong Kong will pick up on Monday from the north, and wind direction should turn in a counter-clockwise manner to the west on Tuesday and Wednesday.
明天將繼續有煙霞。按照目前預測路徑，北風將於星期一增強，並逐漸於隨後兩日以逆時針方向轉為偏西風。

Tropical disturbance 91W in northern South China Sea intensified into tropical depression 07W today. At 20 HKT, 07W was centred
about 800 km (430 NM) SSE of Hong Kong.
The subtropical ridge has partially retreated from the South China Sea. The western edge is expected to steer 07W northwards in the next 48 hours, though the steering is weak and forward speed is expected to be low. The ridge may re-extend later in the forecast period to induce a more westerly motion.
Current T-number: T2.0/2.0/INT OBS
With high sea temperatures and low shear, 07W should be able to intensify at about climatological rate in the next 72 hours.
