01W is now crossing southern Philippines. At 2 pm, 01W was centred about 590 km (320 NM) SE of Manila.

01W 正橫過菲律賓南部。在下午 2 時，01W 集結在馬尼拉東南約 590 公里 (320 海里)。

01W is moving westwards along the low-level easterlies. Due to the influence of an anticyclone in South China Sea, 01W may dip southward in the next 24 hours before turning to WNW as the Pacific subtropical ridge strengthens and assumes dominance. The storm is then expected to move WNW until the end of the forecast period.

01W 正沿低層偏東氣流向偏西移動。受南海一反氣旋的影響，01W 於未來 24 小時或會略為南移，隨後太平洋副熱帶高壓脊增強並成主要駛流動力，預料風暴將轉西北偏西移動，直至預測期完結。

01W's convective bandings became better defined last night, but they appear to have loosened this morning. Little, if any, development is expected in the next 24 hours as the storm crosses the Philippines. Conditions are not very favourable in the South China Sea either, and thus significant development is not expected through t+72. It should be noted that a few numerical models are suggesting some intensification after t+72.

01W 的旋捲度於昨天轉好，但今天對流變得鬆散。由於風暴將於未來 24 小時橫過菲律賓，預料它不會有所增強。同時，南海的大氣環境也不太理想，預料風暴於未來 72 小時亦不會有明顯發展，但值得注意部分數值模式預測 01W 於 72 小時後有可能開始增強。

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

預料 01W 於未來的 72 小時將不會對香港構成影響。

Tropical depression 01W formed just off the southeastern Philippine coast today. At 2 pm, 01W was centred about 810 km (440 NM) SE of Manila.

熱帶低氣壓 01W 今天於菲律賓東南部對開形成。在下午 2 時，01W 集結在馬尼拉東南約 810 公里 (440 海里)。

01W is moving WNW along the low-level easterlies. The Pacific subtropical ridge is expected to strengthen and push 01W towards the west across the Philippines and into the South China Sea in the next 2-3 days.

01W 正沿低層偏東氣流向西北偏西移動。預料太平洋副熱帶高壓脊會增強，並帶領 01W 西移，於未來兩三天橫過菲律賓並進入南海。

Current T-number 現時的 T 號碼: T1.5/1.5/INT OBS

01W's convections are concentrated in its northern periphery. Although sea temperatures are sufficient for tropical cyclone development, vertical wind shear is not low and the storm is about to track across landmass. 01W is not expected to intensify in the next 24 to 48 hours. There is more uncertainty after t+48, but numerical models do not support 01W's development. The storm is expected to remain weak in the South China Sea.

01W 的對流集中在其北部。雖然海溫適合熱帶氣旋發展，但該區垂直風切變不低，風暴亦即將橫過路地，因此預料風暴不會於未來 24 至 48 小時增強。48 小時後之不確定性較大，但數值模式普遍不支持 01W 的發展，預料它於南海時將維持較弱的強度。

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

預料 01W 於未來的 72 小時將不會對香港構成影響。
