04W was named MATMO by JMA last night and has been moving N to NNE in the past 24 hours. At 14 HKT, MATMO was centred about 890 km (480 NM) W of Iwo Jima.
MATMO will move ENE along the NW periphery of the subtropical ridge in the rest of the forecast period.
麥德姆將於餘下時間沿副熱帶高壓脊西北部向東北偏東移動。
Intensity Analysis 強度分析
Current T-number: T3.0/3.0/D0.5/24 HRS
MATMO is about to start extratropical transition and will be converted into a temperate cyclone in 24 to 36 hours.
現時的 T 號碼: T3.0/3.0/D0.5/24 HRS 麥德姆即將開始轉化為溫帶氣旋,並預料會在 24 至 36 小時後轉化完成。

04W is currently situated W of the steering subtropical ridge. Together with the arriving mid-latitude trough that is expected to weaken the ridge, 04W will move NE to ENE in the rest of the forecast period.
Current T-number: T2.5/2.5/D0.5/18 HRS
04W will intensify slightly as it consolidates under a rather good environment with light shear, but will weaken after t+24 as it encounters stronger vertical wind shear. It will start extratropical transition near t+36.

A disturbance (96W) east of Luzon has strengthened into a tropical depression, and was given a temporary number 04W. At 20 HKT, 04W was centred about 340 km (190 NM) NE of Manila.
04W is currently situated W of the steering subtropical ridge which will induce northward movement in the next 24 hours, after which an arriving mid-latitude trough will cause the ridge to retreat and allow 04W a full recurvature.
Current T-number: T2.0/2.0/INT OBS
04W will intensify slightly as it consolidates under a rather good environment with light shear, but will weaken after t+36 as it encounters stronger vertical wind shear. It will start extratropical transition near t+48.
