A snow and ice event is underway across the Deep South, threatening travel nightmares and widespread power outages.
Flight cancellations surpassed 1,500 on Tuesday morning, with more than half of the cancellations coming to or from Atlanta. Hundreds more were canceled into and out of Charlotte and Dallas.
Travel conditions are also hazardous on roadways. Accidents were reported overnight in Mississippi and Alabama as roadways became slick, with all southbound traffic on I-55 blocked for hours near exit 265 in Mississippi.
The governors of Alabama and Georgia declared states of emergency Monday night in preparation of the storm.
The poor travel conditions for the South will intensify Tuesday night into Wednesday before the storm starts to push up to the Northeast.
"A number of communities over the interior South may have more significant, longer-lasting ice and snow when compared to the storm from late January," AccuWeather.com Southern Weather Expert Meteorologist Dan Kottlowski said.
