美國舊金山灣區昨(20日)受到暴風雨侵襲,各地因暴雨及颶風影響傳出淹水、土石流、斷電及道路封閉等災情,加州中央谷地(Central Valley)晚間更緊急疏散近500位居民。
根據《水星報》(Mercury News)及美國國家廣播公司(NBC)報導,加州中部受到此次暴風雨影響最為劇烈,最大雨量落在蒙特瑞郡(Monterey County)的著名風景區「大索爾」(Big Sur),24小時內降雨量達到5.91英吋(約150毫米),住在卡梅爾河(Carmel River)河畔的居民也被告知撤離。
雨勢也造成陸上交通秩序大亂,北邊的聖塔克魯茲(Santa Cruz)的17號公路山區路段及南向部分道路,因倒塌的樹木及土石流於周一下午暫時封閉。南灣區聖荷西的280號州際公路也因為淹水而禁止通行。
除此之外,舊金山國際機場亦受到嚴重干擾,近300個航班延誤,100架班機遭到取消。各地現無傷亡消息,僅傳出聖荷西2名街友受困於溪水暴漲的野狼溪(Coyote Creek),並且已於當日下午獲救。(陳其仙/綜合外電報導)

(02/13) 美國加州北部奧羅維爾鎮附近大水壩(美國最高水壩)有一條輔助排洪道有倒塌的危險,奧羅維爾鎮皆可能受到威脅,該小鎮住了大約16260人,當局星期日(2/12)下令緊急疏散住在水壩下面小鎮的居民。

美國全國最高水壩恐崩塌 13萬人疏散

美國全國最高的水壩、位於加州北部奧羅維爾鎮附近的大水壩有一條輔助排洪道有倒塌的危險,當局星期日下令住在水壩下面小鎮的居民緊急疏散,之後將疏散人數擴大至13萬人,居民爭相駕車離開,附近交通擠塞。

北加州比尤特縣行政司法長官辦事處在社交網站張貼告示,內容說:「奧羅維爾鎮低窪地區及下游一帶的居民都要立即疏散,離開家園。這『不是』演習。這『不是』演習。這『不是』演習。」

加州水利部門也於美國西岸時間星期日下午4時半左右在Twitter發布訊息,預測那條排洪道會在未來1小時內抵受不住而倒塌。

出問題的是加州聖克拉門抵市以北105公里外的奧羅維爾湖水壩。工作人員較早時進行檢查時發現其中一條輔助排洪道有大面積的石屎塊剝落。州政府部門和工程人員上周四採取緊急措施,小心翼翼排洪,以減輕水壩的壓力。

那座水壩位於奧羅維爾鎮以東的上游位置,該個小鎮住了大約16260人。萬一排洪道倒塌,他們都可能受到威脅。當局局星期日下令住在水壩下面小鎮的居民緊急疏散,之後更將疏散人數擴大至13萬人。

奧羅維爾大水壩於1962至1968年建造,主體高達230公尺(770呎),成為全美最高的水壩,比位於亞利桑那州和內華達州交界處的著名胡佛水壩還高出12公尺(40呎)。

Oroville Dam risk: Thousands ordered to evacuate homes
From the section US & Canada

Media captionWater flows from Oroville Dam’s emergency spillway for first time in history
More than 180,000 people in northern California have been told to evacuate their homes after an overflow channel at the tallest dam in the US was weakened by heavy rainfall.
The emergency spillway of the 770 ft (230m) tall Oroville Dam was close to collapse, officials said.
The excess water has now stopped flowing.
However, late on Sunday Butte County Sheriff Kory Honea said the evacuation orders remained in place.
Water levels in the reservoir have risen following heavy rain and snow after years of severe drought.
It is the first time that Lake Oroville has experienced such an emergency in the dam’s near 50-year history.
The California Department of Water Resources said earlier on Sunday afternoon that it was releasing as much as 100,000 cubic feet (2,830 cubic metres) of water per second from the main spillway to try to drain the lake.
In a statement posted on social media on Sunday afternoon, the sheriff for the area around the Lake Oroville dam ordered residents to evacuate, repeating three times that it was “NOT a drill".

The local sheriff's evacuation order, posted on Facebook, was shared over 14,000 times by Sunday evening

Residents of Oroville, a town of 16,000 people 65 miles (105km) north of Sacramento, were told to head north.

There was gridlock on roads heading out of the town, with some evacuees complaining that they should have been given more warning.

Butte County’s official Twitter feed shared news of emergency shelters, and reported that many hotels were fully booked in the wider area.

Other cities affected should follow orders from their local law enforcement agencies, officials said.

Earlier in the week engineers began releasing water from the dam after noticing large chunks of concrete were missing from a spillway.

On Friday, California Governor Jerry Brown asked the Federal Emergency Management Agency to declare a major disaster due to flooding and mudslides brought on by storms.

乾旱多年 南加州遭遇暴風雨 至少六死
更新: 2017-02-18 11:44 PM 標籤: 美國天氣, 加州, 暴風雨
【大紀元2017年02月18日訊】(大紀元記者吳英綜合報導)加州17日遭遇多年來首見的強烈暴風雨,南加州首當其衝,洪水淹沒高速公路,至少6人遇難。

《今日美國》報導,不同於上週肆虐加州的暴風雨,17日下午開始的豪雨,伴隨時速高達70英里(約113公里)的強風,帶來重大災害。洛杉磯出動所有消防、工程等單位人員,應對各種可能情況。

洛杉磯警察說,在謝爾曼奧克斯市(Sherman Oaks)Sepulveda大道,強風導致電線桿倒在一輛汽車上,司機遭電擊致死。

暴雨淹沒洛杉磯附近5號州際公路,水深達5英尺(約152公分)。高速公路巡邏員指引駕車人避開淹水區,有些大型卡車駕駛冒險涉水。

「這是一個強大風暴,短時間內產生巨大影響」,國家氣象局(National Weather Service)氣象學家Derek Schroeter說,「18日上午雨勢和風勢都會減弱,會有零星陣雨。」在經過多年乾旱後,這場暴雨帶來4到6英尺(122到183公分)的雨量。

河濱縣(Riverside County)當局呼籲民眾嚴防洪災,避免高淹水區,遵守封路標誌,不要冒險涉水。

在15號州際公路上,一輛消防車被洪水沖出車道,所幸車上的所有消防員都順利逃生。在加州製片場市(Studio City),兩輛車落入一個大坑,至少一人受傷。

位於西湖村(Westlake Village)的拉斯維京斯(Las Virgenes)水庫,水位來到40多年來最高,該水庫自1974年首次充滿水量後,從來沒有洩洪過。當局說,目前該水庫沒有安全顧慮。

上週加州一場大雨,造成北加州奧羅維爾(Oroville Dam)水庫洩洪道出現坑洞,危及擋水牆系統,當局緊急疏散近20萬人。日前撤離令取消,民眾返家。

南加州風暴侵襲 土石流加淹水釀2死
2017/02/18 15:32

美國南加州遭受強烈風暴襲擊,目前已知至少2人死亡,強風吹倒樹木及電纜造成各地大停電,豪雨直撲山區,帶著大量泥沙衝下山,不少居民被迫撤離。市區內馬路變成小河,還有一座3層樓高的停車場,變身大瀑布,讓民眾驚呼太誇張了。

大水順著樓梯往下衝,越過欄杆變成3層樓高的大瀑布,馬路上水淹到膝蓋,開車像在衝浪,引起民眾陣陣驚呼。

氣象主播:「這大概是近期來最嚴重的一場暴風雨,不幸已經造成2人死亡,風雨還帶來打雷閃電,來看看首當其衝的地區是什麼模樣,實在令人難以置信,他們得把100多年的樹砍掉,因為它被強風吹倒了。」

美國南加州碰上近年來最嚴重暴風雨,五號州際公路水深1.5公尺,造成交通大打結,狂風夾著豪雨直撲山區,土壤禁不住沖刷造成嚴重土石流,許多民眾緊急撤離家園。

記者:「看看水的顏色濁到像巧克力一樣,帶著褐色的綠,都是從山上沖下來的土。」

除了豪雨下不停,最高風速達到每小時150公里,相當於中度颱風的程度,在海邊掀起巨浪,各地頻傳停電意外。

記者:「這裡的強風吹翻電纜,還有許多樹木、紅綠燈也都壞了,還傳出有變電箱爆炸。」

進出南加州的幾百架航班幾乎全部取消,這場暴風雨雖然為乾旱5年的加州解渴,不過也帶來超乎想像的嚴重災情。

美國加州近期遭遇連續多場暴風雨天氣來襲,狂風暴雨加上冰雹天氣,導致多處地區出現淹水以及泥石流等嚴重災情。加州州長布朗(Jerry Brown)昨晚宣布,加州50個縣市進入緊急狀態。

過去兩個星期以來,加州各地普降暴雨,造成不同程度的災情,包括房屋和道路淹水、車輛受困、路樹倒塌、泥石流以及公路受損等,災情還釀成人員傷亡。在這段期間因為暴雨天氣導致至少4人死亡、3人失蹤以及大批民眾需要救援人員在洪水中搜救,險象環生。

加州州長宣布進入緊急狀態的50個縣市,包括南加州洛杉磯、聖伯納迪諾、聖塔芭芭拉以及聖地牙哥等地,還有北加州的州府沙加緬度、舊金山、阿拉米達縣、馬林縣與納帕縣等等,受影響區域涵蓋了加州北、中、南地區。

布朗州長的這項緊急狀態令,主要有兩項緊急告示,對於近期受嚴重風暴災情影響的縣市,確保有撥款可以提供災區因應暴雨帶來的損壞並且重建當地社區。
