On Wednesday morning, the temperature in Miami dropped to 40 degrees with a windchill in the mid-30s

Parts of Florida recently received a wild weather advisory: watch out for flurries of frigid, falling iguanas.

According to CNN, the Sunshine State recently experienced a cold snap with temperatures dropping 10 to 15 degrees below the norm for this time of year.

These cooler temperatures were felt across the southeastern United States, but only Florida was warned about an odd side effect that can come from a sudden drop in temperature.

“This isn’t something we usually forecast, but don’t be surprised if you see Iguanas falling from the trees tonight as lows drop into the 30s and 40s. Brrrr!” the National Weather Service — Miami tweeted on Tuesday.

The unusual tweet went on to add that iguanas are cold blooded, so they “slow down or become immobile when temps drops into the 40s. They may fall from trees, but they are not dead.”

On Wednesday, the National Weather Service confirmed that their forecast was correct, retweeting a photo of a fallen iguana shared by National Hurricane Center scientist Eric Blake.

“Verified the iguana warning and the wind chill advisory! Definitely not your average day in South Florida this morning,” NHS-Miami wrote along with a photo of an iguana lying on pavement.

Several other Floridians also shared photos of the chilly, incapacitated iguanas they found in their yards.

USA Today reports, via the National Weather Service, that the temperature in Miami dropped to 40 degrees on Wednesday morning and that the windchill in the area was in the mid-30s.

Iguanas, native to Central America and parts of the Caribbean and South America, are considered an invasive species in Florida, with Florida Fish and Wildlife going as far as encouraging Florida residents to kill iguanas they find on their property.
