The most recent cold blast that sent Florida into freezing temperatures was good for at least one thing: helping get rid of thousands of invasive iguanas from our ecosystems.

A South Florida iguana expert gathered dozens of motionless reptiles Sunday morning as a cold snap swept through the region, causing temperatures to dip into the mid-30s. The cold-blooded iguanas fall from trees when chilled.

The eastern two-thirds of the United States is experiencing some of the coldest weather of the autumn season.

The upcoming cold snap in the Sunshine State will be intense enough to make Iguanas rain from the sky in South Florida.

Florida is dealing with a strange problem.

Iguanas are an invasive species in Florida, causing problems for the state's environment, but one South Florida city has felt the impacts of the reptiles more directly after one caused a large power outage.

MIAMI – The National Weather Service routinely warns people about falling rain, snow and hail, but temperatures are dropping so low in South Florida the forecasters are warning residents about falling iguanas.

The low temperatures stun the invasive reptiles, but the iguanas won’t necessarily die. That means many will wake up as temperatures rise Wednesday. Iguanas aren’t dangerous or aggressive to humans, but they damage seawalls, sidewalks, landscape foliage and can dig lengthy tunnels.
