Ralf Geithe/iStock(MIAMI) — As temperatures drop in Florida, so do the iguanas.

With lows hitting the 30s and 40s in the Miami area Tuesday night, iguanas have become so cold that they slow down or become entirely immobile and fall from the trees, according to the National Weather Service Miami-South Florida.

“This isn’t something we usually forecast, but don’t be surprised if you see iguanas falling from the trees tonight,” a tweet from the National Weather Service (NWS) said.

The surprising notice was still in place Wednesday morning.

“Definitely not your average day in South Florida this morning,” the National Weather Service tweeted, along with a photo of a fallen iguana.

The NWS assured the public that the lizards, which are cold blooded, are not dead.

Iguanas are not native to Florida and considered an invasive species, according to the state’s Fish and Wildlife Conversation Commission. They were first reported in the state in the 1960s in Hialeah, Coral Gables and Key Biscayne along Miami-Dade County’s southeastern coast.

Social media posts poured in Wednesday morning, as early risers got a first-hand look at the downed iguanas.
