CHAN-HOM's cloud bands kept spiraling about a common centre and the system did not die out within 24 hours of the last bulletin. As CHAN-HOM remained a weak depression our site resumed bulletins on it. At 14 HKT, CHAN-HOM was centred about 520 km (280 NM) S of Okinawa.

燦鴻的雲帶於本站最後發佈 24 小時後仍然維持其螺旋性。由於燦鴻繼續保持熱帶低氣壓強度,本站再度作出發佈。在 14 HKT,燦鴻集結在沖繩島以南約 520 公里 (280 海里)。

Movement Analysis 路徑分析

CHAN-HOM is now situated west of a subtropical ridge. It is forecast to move north in the next 24 hours.

燦鴻現正在副熱帶高壓脊的西面,預料它將於未來 24 小時向北移動。

Intensity Analysis 強度分析

Current T-number: T1.0/1.0/S0.0/24 HRS
The weakening of vertical wind shear allowed CHAN-HOM to barely survive on sea. However sea temperatures are reaching 23 degrees Celsius in the vicinity of CHAN-HOM and is expected to decline as it travels further north. This will cause CHAN-HOM to dissipate in the short run.

現時的 T 號碼: T1.0/1.0/S0.0/24 HRS
由於呂宋海峽以東附近的垂直風切變大幅減弱,所以燦鴻可在洋面上維持其低層環流中心。預料在不斷下降的海水溫度之影響下 (現只有約攝氏 23 度),燦鴻將於短期內消散。

Effects on Hong Kong 對香港的影響

No threat to Hong Kong is expected within the next 72 hours.

燦鴻於未來的 72 小時將不會對香港構成任何影響。

Next Update 下次更新

Unless CHAN-HOM remains strength in the next 48 hours, this is the final bulletin on the system.

除非燦鴻於未來 48 小時內維持強度,否則這是本站對它的最後一次發佈。

CHAN-HOM weakened gradually as it travelled eastwards. At 20 HKT, CHAN-HOM was centred about 860 km (460 NM) ENE of Manila.

燦鴻繼續減弱。在 20 HKT,燦鴻集結在馬尼拉東北偏東約 860 公里 (460 海里)。

Movement Analysis 路徑分析

CHAN-HOM will turn north soon as it is now steered by the subtropical ridge which extends to the west.

隨著副熱帶高壓脊西移,燦鴻將轉受它的影響而轉向偏北方向移動。

Intensity Analysis 強度分析

Current T-number: T1.5/2.0/D1.5/24 HRS
Sea surface temperatures are only marginal for CHAN-HOM to survive; its cloud bands are also sheared to the east. Under such unfavorable circumstances CHAN-HOM will dissipate very soon.

現時的 T 號碼: T1.5/2.0/D1.5/24 HRS
海面溫度只能勉強令燦鴻生存,而偏強的垂直風切變亦令燦鴻的對流向東切離在這惡劣的環境下,預料燦鴻將於短時間內消散。

CHAN-HOM made landfall at Luzon last night, weakening significantly while traversing northern Philippines. It is now in open waters again. At 14 HKT, CHAN-HOM was centred about 500 km (270 NM) NE of Manila.

燦鴻於昨晚登陸呂宋,再橫跨菲律賓時大幅減弱,並於今早再次接觸洋面。在 14 HKT,燦鴻集結在馬尼拉東北約 500 公里 (270 海里)。

Movement Analysis 路徑分析

A high pressure region developed north of CHAN-HOM. As the steering from the near-equatorial ridge diminishes and its direction of steering shifts, CHAN-HOM will gradually turn to a N to NNW track soon.

一個高壓區於燦鴻北部建立。隨著由低緯高壓帶來的偏西氣流減弱並改變方向至南北向,預料燦鴻將轉向北至西北偏北移動。

Intensity Analysis 強度分析

Current T-number: T3.0/4.0/D2.0/24 HRS
CHAN-HOM weakened as it travelled on land. It is expected to weaken gradually in hostile environments and will dissipate over water about three days later.

現時的 T 號碼: T3.0/4.0/D2.0/24 HRS
燦鴻於橫過陸地時大幅減弱由於北緯 18 度以北的環境持續惡劣 (甚高垂直風切變和較低海水溫度),預料燦鴻將於北上時逐漸減弱,並於約三天後在海上消散。

Effects on Hong Kong 對香港的影響

No threat to Hong Kong is expected within the next 72 hours.

CHAN-HOM intensified further and is edging to the Philippines. At 14 HKT, CHAN-HOM was centred about 280 km (150 NM) WNW of Manila.

燦鴻繼續增強並靠近菲律賓。在 14 HKT,燦鴻集結在馬尼拉西北偏西約 280 公里 (150 海里)。

Movement Analysis 路徑分析

The westerly airstream was stronger than expected and CHAN-HOM speeded across the South China Sea last night. It is expected that the steering airstream will diminish and cause CHAN-HOM to decelerate near the Philippines. It is currently expected that the absence of the dominant steering together with the westward extension of the subtropical ridge in the Pacific will induce CHAN-HOM to travel northwards with some westward component in the latter part of the forecast period.

由低緯高壓所帶來的偏西氣流比預期強,令燦鴻昨夜急速向偏東方向移動。預料該引導氣流將於稍後減弱,令燦鴻的移動速度降低。預料在太平洋的副熱帶高壓脊將西伸並為燦鴻提供向北或西北偏北的引導氣流,從而令燦鴻在菲律賓附近轉向。

Intensity Analysis 強度分析

Current T-number: T5.0/5.0/D1.0/24 HRS
CHAN-HOM intensified in warm waters; however a weakening trend will be observed as CHAN-HOM is about to make landfall. The location that CHAN-HOM starts to turn north will affect the extent of the weakening. As hostile environment persists at latitudes north of 18N, CHAN-HOM is expected to weaken significantly during its anticipated recurvature to the north.

現時的 T 號碼: T5.0/5.0/D1.0/24 HRS
受到較暖海水影響,燦鴻增強為二級颱風隨著燦鴻接近陸地,它即將開始減弱減弱的程度亦取決於燦鴻路徑轉北的位置另外,由於北緯 18 度以北的環境持續惡劣,預料燦鴻將於北上時明顯減弱

Effects on Hong Kong 對香港的影響

No threat to Hong Kong is expected within the next 72 hours.

燦鴻於未來的 72 小時將不會對香港構成任何影響。

CHAN-HOM continued to consolidate and turned NE to ENE in the meantime. At 14 HKT, CHAN-HOM was centred about 340 km (180 NM) SSE of Paracel Islands (Xisha).

燦鴻繼續整固,並於昨晚開始轉向東北至東北偏東移動。在 14 HKT,燦鴻集結在西沙東南偏南約 340 公里 (180 海里)。

Movement Analysis 路徑分析

The westerly airstream from a near-equatorial ridge is currrently steering CHAN-HOM to the east. This steering will diminish two days later, and CHAN-HOM will decelerate in the vicinity of the Philippines. It is currently expected that the absence of the dominant steering together with the westward extension of the subtropical ridge in the Pacific will induce CHAN-HOM to travel northwards in the latter part of the forecast period.

一個低緯高壓所帶來的偏西氣流正令燦鴻向偏東方向移動。該引導氣流將於預測後期減弱,令燦鴻的移動速度降低。預料在太平洋的副熱帶高壓脊將西伸並為燦鴻提供向北的引導氣流,從而令燦鴻在呂宋附近向北移動。

Intensity Analysis 強度分析

Current T-number: T4.0/4.0/D0.5/24 HRS
Situated in the middle of the South China Sea, CHAN-HOM is receiving considerable amount of heat from the water and that the ambient environment is generally decent for intensification. A weakening trend will be observed as CHAN-HOM nears the Philippines. The location that CHAN-HOM starts to turn north will affect the extent of the weakening. As hostile environment persists at latitudes north of 18N, CHAN-HOM is expected to weaken significantly during its anticipated northward journey.

現時的 T 號碼: T4.0/4.0/D0.5/24 HRS

CHAN-HOM progressed northwards in the past 24 hours and has intensified into a severe tropical storm. At 14 HKT, CHAN-HOM was centred about 530 km (280 NM) S of Paracel Islands (Xisha).

燦鴻昨晚向北移動,並增強為強烈熱帶風暴。在 14 HKT,燦鴻集結在西沙以南約 530 公里 (280 海里)。

Movement Analysis 路徑分析

The near Beibu Wan weakens and now the north to northeasterly airstream dominates. The airstream from a low-latitude ridge will contribute to its eastward movement before the storm reaches Philippines. This steering will diminish as CHAN-HOM weakens upon reaching the Philippines and a gradual poleward movement is expected.

在北部灣的高壓區已減弱。預料處於低緯度的高壓所帶來的氣流會帶領燦鴻在預測中期向偏東方向移動。該引導氣流將於預測後期減弱,令燦鴻的移動速度降低。燦鴻預料會在預測後期再度轉向偏北移動。

Intensity Analysis 強度分析

CHAN-HOM is at a location where sea temperatures are very favorable. It should be able to intensify in the next 72 hours. It will weaken as it nears Luzon.

97W has intensified into a tropical storm (02W) and was named CHAN-HOM. At 14 HKT, CHAN-HOM was centred about 1030 km (560 NM) WSW of Manila.

97W 增強為熱帶風暴 02W 並被命名為燦鴻。在 14 HKT,燦鴻集結在馬尼拉西南偏西約 1030 公里 (560 海里)。

Movement Analysis 路徑分析

A ridge near Beibu Wan is providing steering that counteracts with the southwesterly flow southeast of CHAN-HOM which together contributed to its slow movement. CHAN-HOM is forecast to move NNE before the passage of a trough that will terminate the steering from the north and the system will turn eastwards near t+48.

在北部灣的一個高壓區正帶來一股與燦鴻東南面的西南氣流抗衡的力量,使燦鴻移動緩慢。預料一道西風槽將截斷燦鴻北面的由東北向西南移的力量,從而使它受西南氣流的影響而向東至東北偏東移動。

97W has intensified into a tropical depression. At 14 HKT, 97W was centred about 330 km (180 NM) WSW of Spratly Islands (Nan Sha).

97W 增強為熱帶低氣壓。在 14 HKT,97W 集結在南沙西南偏西約 330 公里 (180 海里)。

Movement Analysis 路徑分析

The steering forces on 97W are very similar to that on KUJIRA. It is expected that the arrival of a mid-latitude trough will weaken the steering force to the north of the system; it will then be exposed to the force driven by the northwestern quadrant of the subtropical ridge southeast of it and will track NE to ENE.

一道西風槽的到來將截斷 97W 北面的由東北向西南移的力量,從而使它受東南部的副熱帶高壓脊的影響而向東北至東北偏東移動。
