Due to the freezing conditions brought on by what feels to be the coldest Christmas in the State in 33 years, AAA issues a warning to tourists and residents of Florida that flights may be canceled.
Northern and central Florida experienced overnight lows in the 20s, and the Big Bend and Panhandle region are under a hard freeze warning that lasts until Monday at 9 AM.
Even though wind chills in many places may have made it feel that way, the temperatures did not actually break the record for the coldest Christmas. It's probably among the top five, trailing only the Christmas cold wave of 1983 and the Christmas of 1989, which continue to hold the record for the majority of the nation.
As of Sunday morning, authorities across the country had identified at least 18 fatalities as storm-related. Forecasters anticipate that the massive area of cold air covering the nation will continue to bring subfreezing temperatures into the following week.
According to the Weather Prediction Center, for the majority of locations in the South outside of south Florida, wind chills will still reach their lowest points Monday and Tuesday morning in the 20s and low 30s.
Canceled Flights
AAA advises the 112 million holiday travelers who plan to travel more than 50 miles to check their flights. There are still thousands of canceled and delayed flights.
The online flight tracker FlightAware reported nearly 13,000 delays and more than 5,600 cancellations for flights within, into, or out of the US on Sunday as of 5:00 PM ET.
With Denver having the most flight delays and cancellations, FlightAware's "Misery Map" showed over 900 delays in addition to over 200 cancellations between 2 PM and 6 PM ET on Sunday.
Where blizzards occur in the central and eastern United States, the National Weather Service issued a warning about whiteout conditions on the roads.
