"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," NWS tweeted.  

Because they're cold-blooded, iguana's bodies can stiffen up and fall out of trees, appearing to be dead. Once temperatures reach the 40s, they become immobile.

If you happen to come across one, don't touch them. Eventually, they'll warm back up and won't be happy to see you.

They have caused damage to infrastructure, including seawalls and sidewalks, according to agencies in charge of managing the hundreds of miles of canals that channel water throughout South Florida
