Forty-million people along the U.S. East Coast are bracing themselves for what weather forecasters are calling a "bomb cyclone" - a massive winter storm blowing through the Atlantic Ocean.

The brutal winter weather has already brought snow to the southeastern United States, which is not used to dealing with wintry conditions.

The approaching storm could dump more than 20 centimeters of snow on Boston, Massachusetts where schools are closed Thursday.

"Our prime focus will be cleaning sidewalks and main arteries, roadways and responding to public safety requests... and responding to people who call in... as we move forward I'm asking people to be patient, " Boston mayor, Marty Walsh said.

The frigid conditions already gripping a large swath of the United States will get a jolt from the storm, which is expected to bring hurricane-force winds to the New England coast and into Canada.

Forecasters say much of the country can expect another wave of dangerously-cold weather later this week before temperatures moderate.

來自大西洋的一場特大風暴“炸彈氣旋”星期四橫掃美國東海岸地區，多達4千萬人將深受影響。

“炸彈氣旋”令美國通常氣候溫暖的東南部地區也開始降雪。

麻薩諸塞州的波士頓的積雪可能會高20多厘米。當地的學校星期四都停課。

波士頓市長馬迪·沃爾什說：“我們的工作重點是清理便道、主要干線和道路，并對公共安全需要及打電話求助的民眾做出反應。在我們應對人民需要的時候，我請大家要耐心”。

今年入冬以來，美國大片地區都一直處在嚴寒之中，而這場暴風雪將給新英格蘭地區以及加拿大帶來颶風級的大風。

氣象預報說，美國大部分地區本周末將迎來另一波嚴寒天氣，然后氣溫才會逐漸回暖。
