If you thought Monday night was cold, hold on to your booties.
Temperatures across South Florida will dip even lower into the 30s tonight and possibly the 20s in some inland areas, forecaster predict, and the falling degrees are getting into dangerous territory for humans, animals and crops.
Freeze warnings have been issued for parts of West Palm Beach, Fort Lauderdale and Miami-Dade and local shelters have opened doors early in an effort to entice people sleeping on the streets to come in from out of the dangerous cold.
Some cities have issued state of emergencies because of the dramatic weather change. Such plans are more commonly reserved for heat waves, not cold fronts.
Farmers will also be bundled up as they try to salvage crops that could be damaged by the freezing temps. The fear is the mercury will drop to 32 degrees, officially freezing.
Residents got a good taste of the cold Tuesday morning, when many cities broke long-standing record lows.
Fort Lauderdale residents woke up to 40-degree temperatures, which broke a 169-year-old record for the area. Miami was even colder, with some thermometers touching the 30s.
