A “generational” Arctic blast brought dangerously cold temperatures to swaths of the northeastern United States and Canada on Saturday, with forecasters warning that frostbite could occur in just five minutes.
Atop Mount Washington in New Hampshire state, the wind-chill factor reached -78 degrees Celsius (-108 degrees Fahrenheit) overnight, the National Weather Service (NWS) said.
That broke the previous low recorded there of -74C (-101F), the Weather Channel said.
The NWS office in Caribou, Maine, said a wind chill of -51C (-29F) was recorded in the small town of Frenchville, just south of the border with Canada.
“This is an epic, generational arctic outbreak,” the office had warned in an advisory in advance of the front.
