Miami, Florida – South Florida expects colder-than-average temperatures on Christmas weekend, but that's not the only strange weather phenomenon residents should watch out for.

The National Weather Service issued a warning that South Florida wildlife would also be affected by the colder temperatures.

On December 21, the NWS tweeted: "Brrr! Much colder temps expected for Christmas. Low temperatures in the 30s/40s and falling Iguanas are possible. Keep up with forecast changes and stay warm!"

According to Local 10 News, green iguanas are an invasive species first reported in Florida in the 1960s. They inflict significant damage on local canals, seawalls, and sidewalks. Female iguanas can lay around 80 eggs per year!

Currently, Florida iguanas are protected only by anti-cruelty laws.

This Christmas, the low temperatures may take their toll on the reptiles. The cold may stun the iguanas, causing them to fall from the trees.

Families out for a Christmas stroll should watch out they don't get struck by a falling iguana!

The good news is, the iguanas will not necessarily die. They will likely wake up once it gets a little warmer outside!
