Miami, Florida - It's raining iguanas again in Florida, as record-low temperatures caused by winter storm Elliott are making paralyzed reptiles drop out of trees.

With a historic arctic cold front blasting much of the country, Floridians will see even more frozen iguanas plop into yards and onto patios than usual.

The National Weather Service issued a wind chill advisory for Saturday morning, with temperatures forecast in the 40s and feeling even colder.

That means the cold-blooded green iguanas, which rely on external heat to regulate body temperature, may be changing before our eyes. When the mercury drops below 50 degrees Fahrenheit, some go into a hibernation-like state and plummet from above.

"With colder temperatures coming our way this holiday weekend, you might see nonnative green iguanas in a state of torpor, where they temporarily lose all muscle control," the Florida Fish and Wildlife Commission said in a Facebook post.

Though iguanas may look dead when they're in this bizarre condition, they are still very much alive – and potentially dangerous if you mess with them.

The state's advice for those who see one looking paralyzed? Let nature do its thing. They'll wake up sooner or later and go about their iguana business.

While most people leave iguanas alone, whether they're moving or not, anyone with a soft streak should beware: Don't go near a frozen iguana, and certainly don't bring one inside your cozy home to revive it.

Because once these guys thaw out, watch out. They may get aggressive, and you could get scratched or bitten.

"They can recover more quickly than you think and become defensive," the Fish and Wildlife agency said, "using their long tails and sharp teeth and claws."

If you do want to help them out, donate to an organization like Zoo Miami's International Iguana Foundation, which helps generate public awareness about the invasive reptiles.
