LINFA continues to weaken as it moves across land. At 8 am, LINFA was centred about 260 km (140 NM) W of Hong Kong. All tropical cyclone signals were cancelled at 5:50 am.

LINFA weakened rapidly on land despite its proximity to the sea, and is now a tropical depression. At 11 pm last night, LINFA was centred about 60 km (30 NM) NW of Hong Kong. The #8 NW Gale or Storm Signal was in force between 4:40 pm and 10:10 pm yesterday, but has since been replaced by the #3 Strong Wind Signal.

LINFA is gradually losing latitude, and is expected to move WSW to SW before dissipation.

LINFA's convective bands are disintegrating; this is particularly prominent in its southern semicircle. As CHAN-HOM nears, atmospheric environment will deteriorate and LINFA will weaken into an area of low pressure even if it manages to return to the sea.
LINFA weakened quickly and local conditions were not as bad as predicted even though LINFA is still very close to Hong Kong. Winds have already subsided, but showers may continue to affect the territory today with occassional strong gusts. As LINFA moves away and further weakens, the weather will improve during the weekend.
LINFA has intensified into a typhoon, and has just made landfall near Lufeng. At 8 am, LINFA was centred about 270 km (150 NM) E of Hong Kong. The Observatory issued the #3 Strong Wind Signal at 8:40 am today.

LINFA will move W to WSW across coastal Guangdong, and may later turn south into South China Sea again under CHAN-HOM's influence.

LINFA's eye appeared tight on radar images prior to landfall, but was filled soon afterwards. It is expected to weaken gradually due to friction on land. CHAN-HOM's approach to eastern China will limit LINFA's outflow channels, causing it to dissipate near t+72.
LINFA is expected to reach the Pearl River Estuary tonight. Due to LINFA's tight structure, local winds will surge rapidly this afternoon, blowing in from the northwest, gradually backing to the southwest as LINFA passes to the north. The weather will deteriorate in the next few hours; precautionary measures should be completed as soon as possible.
LINFA continued to move north slowly over the past 24 hours. At 8 am, LINFA was centred about 480 km (260 NM) E of Hong Kong. The Observatory issued the #1 Standby Signal at 7:40 am.

A ridge is building in China. LINFA will be steered by this ridge and gradually turn west, making landfall at eastern Guangdong. It is then expected to track W or WSW across coastal Guangdong.
LINFA intensified slightly over the past 24 hours, and appears to be forming an eye on satellite images. It may reach typhoon intensity prior to landfall, but will weaken quickly on land.
As LINFA comes closer, local weather is expected to deteriorate later tomorrow, with squally showers becoming frequent. Westerly winds will prevail, turning to southwest near the weekend. Its effect on Hong Kong depends on how soon it starts its westward turn, as that will determine when will LINFA start to weaken and how close it will reach.

With the lack of a clear steering environment, LINFA is drifting north slowly. There are indications that the subtropical ridge will extend to the west soon, causing LINFA to deflect to the west before CHAN-HOM comes close to eastern China. It will also accelerate when the steering flow strengthens.
LINFA's convections align with the low-level circulation centre again. The storm is expected to intensify slightly in the next 24 hours, before weakening again as it reaches Fujian. It will weaken rapidly on land.
According to the present forecast track, winds in Hong Kong will turn northwest in the next two days. As LINFA comes closer on Thursday and Friday, showers are expected at that time. Its effect on Hong Kong depends on how soon it starts its westward turn, as that will determine when will LINFA start to weaken.

LINFA is expected to move N or NNE along the western periphery of the subtropical ridge in the next 48 hours. Thereafter, CHAN-HOM's approach introduces much uncertainty to its track, while more numerical models are suggesting a deflection back to the west. Our forecast track has therefore been adjusted accordingly.
Proximity to Luzon and heightened shear have caused LINFA to weaken into a tropical storm; its low-level circulation centre has drifted away from its main convective patch and is completely exposed. As LINFA moves north and escapes from northern Philippines, it may reintensify briefly before reaching southern Taiwan and weakening again. By t+96, CHAN-HOM will be close enough to block LINFA's divergence channels, leading to a rapid decay of the cyclone.

LINFA is expected to emerge from the northwestern tip of Luzon. The ridge has weakened sufficiently and should cause LINFA to turn N or NNE in the short term. CHAN-HOM will reach the Ryukyu Islands 4 days later. As CHAN-HOM's track has been adjusted southward, it will very likely come to within 1000 km from LINFA later this week, triggering the Fujiwhara effect. The situation is complicated by LINFA's proximity to Taiwan at that time, while model outcomes diverge considerably. There is rather low reliability on the predicted track beyond t+72.
LINFA should weaken in the next 24 hours due to land interaction. It may reintensify slightly as it crosses Luzon Strait, and later weaken again as it nears Taiwan. The approach of CHAN-HOM will later limit LINFA's convective channel severely, causing the storm to weaken considerably. It may even be absorbed into CHAN-HOM's circulation if it comes close enough.

LINFA will move NW turning to N while the subtropical ridge retreats. As CHAN-HOM heads towards the Ryukyu Islands, it is likely to be close enough to affect LINFA's track. LINFA may move erratically towards the end of the forecast period.
LINFA's structure has improved, although convections are still lacking in its northern semicircle. It is expected to strengthen slightly before touching Luzon, upon which the storm will weaken due to land interaction. Re-intensification inside Luzon Strait is possible.

LINFA will move WNW along the southwestern edge of the subtropical ridge. As the ridge retreats, steering will become weaker and LINFA is expected to turn poleward with a lower speed. As CHAN-HOM heads towards the Ryukyu Islands, it may be close enough to interfere with LINFA's track. Some models are predicting LINFA to move east as a result.
LINFA's convections are concentrated in its southern semicircle. It is expected to intensify gradually in warm seas and generally decent environment, but may weaken later due to its proximity with Luzon.
Tropical disturbance 96W east of the Philippines has intensified into tropical depression 10W. At 2 pm, 10W was centred about 890 km (480 NM) E of Manila.
10W is situated at the southwestern periphery of the subtropical ridge, and is forecast to move WNW in the next 48 hours. As the ridge retreats, steering becomes weaker and the storm will decelerate.
10W's convections are sheared to its west, partially exposing the low-level circulation centre. Vertical wind shear is strong south of the storm, but is weak to moderate elsewhere. The storm is expected to intensify gradually in the next 72 hours.
