對於南太平洋廣泛海域地區來說這已經算是一個非常強烈的熱帶氣旋

對萬那杜而言，Pam 帶來了數十年來最慘烈的風災。

強烈氣旋襲萬那杜宛若邁向世界末日

（中央社雪梨14日綜合外電報導）南太平洋島國萬那杜昨天晚間和今天遭受28年來最強烈風暴侵襲，時速高達250公里的強風摧毀民宅鐵皮屋頂，有報導說災情導致逾44人死亡，但還待聯合國和官方證實。

強風今天持續猛襲首都地區，對外通訊多數中斷。聯合國兒童基金會發言人由維拉港透過電話告訴路透社：「這感覺像邁向世界末日。」

她說：「市中心像有炸彈引爆，既沒電也沒水。」

5級強烈熱帶氣旋帕姆（Pam）昨天深夜侵襲萬那杜，目擊者說，強風掀起高達8公尺巨浪，惡水湧進首都維拉港（Port Vila）。

英國「衛報」（The Guardian）報導，持續關注帕姆的澳洲氣象局說，萬那杜大部分地區都受影響。據報導帕姆最後一刻改變路徑，讓維拉港承受比預期更嚴重的風勢。

聯合國人道事務協調廳（UNOCHA）說，未經證實的報導指出，萬那杜東北部島嶼有44人死亡。但萬那杜政府目前尚未公布官方統計的死傷數據。聯合國人道志工打算明天出動救急，但由於機場關閉且風勢依然狂暴，班機能否成功降落還是問題。

聯合國人道事務協調廳區域主管古尼茨（Sune Gudnitz）由斐濟接受訪問說：「我們恐怕得做最壞打算。萬那杜位在大海中央，位置上非常脆弱。」

帕姆是1987年以來侵襲萬那杜的最強風暴。救難官員說，它的威力堪比2013年侵襲菲律賓的颱風海燕。海燕當時導致6000多人罹難。

帕姆也影響萬那杜鄰國巴布亞紐幾內亞和附近的索羅門群島。救難人員說，巴布亞紐幾內亞已傳出至少1死。

MetService 也指出 ECMWF 預報中心比機構預期還更接近北島，現在也對北島東岸全面發佈暴風警報。

Pam 渦度範圍相當廣大，高反仍盤踞中心使得 Pam 處於西風帶但對流仍未切離。

帕姆經過了萬那杜不少個島嶼. ..
