美国气象局表示,在新罕布夏州的华盛顿山(Mount Washington)山顶,夜间的寒风指数(wind chill factor),亦即在低温和寒风下的体感温度,降到摄氏零下79度,打破之前的零下74度低温纪录。
华盛顿山有1920公尺高,是美国东北部的最高峰,以天气恶劣闻名。气象局表示,4日摄氏零下43度的低温和时速超过177公里的阵风,造成华盛顿山寒风指数再创新低。路透发布一张从华盛顿山州立公园观测台看到的冰封景象,宛如世界末日。
缅因州卡里布(Caribou)的气象局办公室表示,靠近加拿大边界的缅因州小镇法国村(Frenchville)的寒风指数达摄氏零下51度,是“一个世代难得一见的极地寒流”,缅因州东部和北部“自1982年到1988年以来就没再看过这样的寒流”。

Several cities in the northeastern United States enacted emergency measures to protect the homeless population. The Arctic blast also caused "frostquakes" from sudden snaps in frozen soil. https://t.co/8OudQn07b1
