Commuters in the U.S. South face frigid temperatures and dangerously slick roads after a deadly winter storm thrashed the region with heavy snow and winds that snapped power lines.

Schools in New Orleans, charlotte and Atlanta and across the region canceled classes as winter weather advisories from the national weather service remained in effect from eastern Texas to Florida and north into Southeast Virginia.

Wind chill advisories were in effect as temperatures will feel like they had fallen below zero Fahrenheit (-18 degrees Celsius) in parts of the Carolinas, Alabama and Virginia.
