EC預測Pewa未來到西太時強度有中度以上
路徑方面似乎和太平洋高壓很有關係!

CX723-A330

Pewa現已越過東經175度
最快在今日晚上會越洋到西太


現在強度為每分鐘85 km/h,為一熱帶風暴/輕度颱風
入西太後應可以繼續增強到強烈熱帶風暴/輕颱上限
另外,CPHC剛剛把Pewa的預測強度升為Cat. 1了
(P.S:這尤特真是頑強,在中國陸地三天還能生存到...)

48小時後會出現在日本氣象廳的天氣圖裡!

「全般海上警報の種類と記号」完整介紹了，並要知道舉凡 W、GW、SW、TW 也適用未來風力。

過換日線要加一天
還有外面那個颱風遺照館
可能要換一下1312或1313的名字喔

是這邊的週日中午前後跨過換日線，大家別再搞錯了哦。

升格熱帶風暴
第一報路徑圖!

按 CPHC 預測，週日 00Z 與 06Z 之間會進入西北太平洋，理論上 JMA 會先在 00Z 就發報。

名稱會維持 Pewa，國際編號可能是 1312 或 1313，端看潭美是否在週日以前形成。推測 CWB 會譯為「佩瓦」或「佩娃」。
