This is not a joke. The National Weather Service in Florida has issued a "Falling Iguana Alert". Because it is so cold in Florida these days, the cold blooded creatures can become immobile in temps under 40 degrees. That means that lose their grip and can fall from trees to the ground.
But the weather service wants you to know they aren't dead. They're just immobile. They are alive. It's like paralysis. Their eyes are open, they're just frozen. They're going to be fine. Once the sun comes up and the temps rise, they'll be on their way.
"It's been raining iguanas!" Watch this video as they fall, and then wake up.
