Traveling conditions in several states have already become precarious.
More than 170 departing flights from Dallas-Fort Worth International Airport were canceled due to freezing rain at destinations throughout the South.
In Louisiana, police in DeSoto Parish had responded to at least 20 incidents, many on Interstate 49. Lt. Donnie Barber of the sheriff's office said there were no reports of life-threatening injuries.
According to the Louisiana Transportation Department, more than 18 miles of Interstate 220 near Shreveport were closed.
Many bridges in northern Mississippi were iced over, said Brett Carr, a spokesman with that state's emergency management agency.
Carr added that several hundred power customers in Greenville, near the Mississippi River, were in the dark.
Mississippi Gov. Phil Bryant issued a state of emergency "for all counties impacted by the freezing rain, flooding and severe weather."
Tennessee also has issued a state of emergency for areas affected by the weather.
