PEIPAH remained quasi-stationary in the past 24 hours, but generally drifting northwestwards. Meanwhile, PEIPAH became more organized today and has developed a banding eye. At 14 HKT, PEIPAH was centred 610 km (330 NM) SE of Hong Kong.

琵琶於過去 24 小時移動緩慢,但大致向西北移動。此外,琵琶的結構逐漸轉好,並發展出一雲捲風眼。在 14 HKT,琵琶集結在香港之東南約 610 公里 (330 海里)。

Movement Analysis 路徑分析

PEIPAH is now predominantly steered by the subtropical ridge ENE of it, inducing a weak NW movement. A transition in the steering mechanism from the subtropical ridge to a new ridge that extends from northern Vietnam should occur in the next one or two days, after which PEIPAH will travel SW to WSW along the southeastern periphery of the newly-established ridge.

琵琶正沿副熱帶高壓脊的西南部向西北方向移動。隨著在越南北部的另一個高壓脊的建立及東移,琵琶將於一兩天內沿該脊的東南部轉向西南或西南偏西移動。

Intensity Analysis 強度分析

Current T-number: T4.5/4.5/D1.0/24 HRS
PEIPAH is currently situated in an average environment, with moderate sea temperature and vertical wind shear. PEIPAH's future strength will be highly dependent on its future track. In this bulletin, PEIPAH will be able to avoid the high-shear area and remain at typhoon strength before making landfall at Vietnam.

現時的 T 號碼: T4.5/4.5/D1.0/24 HRS
琵琶正處於大致適中的環境,該區海水溫度尚可,而垂直風切變則為中等。琵琶將來所位處的緯度將決定究竟琵琶能否再度增強在本發佈中琵琶將以西南偏西的方向移動,從而避開高垂直風切變之地帶,並維持強度直至登陸越南

Effects on Hong Kong 對香港的影響

Seas south to southeast of Hong Kong may experience strong winds in the next few days.

香港以南/東南的海域將於未來幾天受強風影響

PEIPAH made its first landfall at Luzon last night at about 9 p.m. It has weakened slightly, but has maintained good convective cloud banding structure. PEIPAH has since taken a WNW route, entering HK's 800 km circle. At 14 HKT, PEIPAH was centred 750 km (410 NM) SE of Hong Kong.

琵琶於昨晚九時登陸呂宋,並稍為減弱,但雲團捲旋度仍佳。此外,琵琶轉向西北偏西移動,於今早進入香港 800 公里範圍。在 14 HKT,琵琶集結在香港之東南約 750 公里 (410 海里)。

Movement Analysis 路徑分析

PEIPAH is now predominantly steered by the subtropical ridge ENE of it, inducing a WNW movement. A transition in the steering mechanism from the subtropical ridge to a new ridge that extends from southwestern China should occur in 36 hours' time, after which PEIPAH will travel SW to WSW along the southeastern periphery of the newly-established ridge.

琵琶正沿副熱帶高壓脊的西南部向西北偏西方向移動。隨著在中國西南部的另一個高壓脊的建立,琵琶將於 t+36 小時以後沿該脊的東南部向西南偏西移動。

21W was named PEIPAH last night, and it has intensified rapidly into a category 1 typhoon. At 14 HKT, PEIPAH was centred 380 km (200 NM) NE of Manila.

21W 昨晚被命名為琵琶,並於今天增強為一颱風。在 14 HKT,琵琶集結在馬尼拉之東北約 380 公里 (200 海里)。

Movement Analysis 路徑分析

PEIPAH is expected to move W along the southern periphery of the W extension of a subtropical ridge to the east of the storm in the next 36 hours. A transition in the steering mechanism from the subtropical ridge to a new ridge that extends from southwestern China should occur in 36 hours' time, after which PEIPAH will travel WSW along the southeastern periphery of the newly-established ridge.

預料琵琶會再未來 36 小時沿副熱帶高壓脊的西延部分南端向偏西方向移動。隨著在中國西南部的另一個高壓脊的建立,琵琶將於 t+36 小時以後沿該脊的東南部向西南偏西移動。

Intensity Analysis 強度分析

Current T-number: T4.0/4.0/D1.5/24 HRS
PEIPAH is currently situated in a generally good environment, with moderate sea temperature and low vertical wind shear. PEIPAH should intensify slightly before interacting with the landmass of Luzon. Due to land interaction, PEIPAH will weaken a bit when traversing the terrains of the Philippines. After PEIPAH's emergence from the Philippines, its strength will be highly dependent on its future track. In this bulletin, PEIPAH will be able to avoid the high-shear area to allow intensification before making landfall at Vietnam.
