The brutal frost of the United States

Hello, dear Steemians!

Friends today I bring you this information that is happening

A cold wave to the extreme froze the Midwest of the United States this Wednesday, with temperatures colder than in Antarctica that forced to cancel flights and suspend travel, and paralyzed the lives of tens of millions of citizens.

Colleges and businesses interrupted their usual work. In Chicago the temperature this morning was -30 ° C, with a thermal sensation of -46 ° C because of the icy wind, it was colder than in the capital of the state of Alaska and even more than in some parts of Antarctica.

The cause seems to be a mass of Arctic air that broke away from the polar vortex that usually surrounds the North Pole, triggering the polar wave.
