創紀錄的嚴寒冷凍了美國大片地區

Thousands of schools across the eastern and southern United States were closed Tuesday as a bitter cold front moved into the area after freezing the midwestern section of the country.

Forecasters say temperatures will plunge well below minus 10 degrees Celsius in Washington, D.C., New York, Philadelphia and Boston, while the wind chill, which is the temperature feels like during a strong wind, will be far lower.

The frigid weather is also reaching into the so-called Deep South, including Florida and southern Texas, which usually enjoy moderate temperatures during the cold weather season.

Authorities have decided to close schools to keep children safe from exposure to the extreme cold, which could lead to frostbite within minutes if skin is left exposed.美國東部和南部數千所學校因嚴寒天氣而停課關門，之前美國中西部變得天寒地凍，冷空氣星期二向東部和南部移動。

星期二，波士頓、紐約、費城和華盛頓等東部主要城市預計將迎來低於攝氏零下10度的低溫，加上寒風效應，天氣格外寒冷。

甚至連平時氣候溫暖的佛羅里達州和南部的得克薩斯州，預計氣溫都將低於正常值大約20度。

很多城市已經決定星期二關閉學校。暴露在如此寒冷的氣溫下，幾分鐘內就會被凍傷。
