Alexander Gerst, a German astronaut orbiting Earth from 250 miles (402 kilometres) up, has a warning for humans on the planet below him.

“Watch out, America!” Gerst, who joined the crew of the International Space Station in June, said Wednesday in a tweet featuring pictures he took of Hurricane Florence.

Because of its enormous size and power, the storm has been a recent – if not frightening – muse for astronaut photography.

Here are some of the best images of Hurricane Florence by Gerst and Ricky Arnold, a fellow NASA astronaut living aboard the ISS.

Gerst said Hurricane Florence was so enormous, with a width of more than 500 miles (804 kilometres), that he “could only capture her with a super wide-angle lens.”
