A powerful winter storm that left three people dead in the South is heading to the Mid-Atlantic region of the United States on Wednesday, according to the National Weather Service.

The storm has produced heavy snowfall and numerous tornadoes, according to the National Weather Service. It is pushing toward the mid-Atlantic and is expected to cause widespread showers, moderate to heavy snowfall and possibly tornadoes.

The severe storms Wednesday are "capable of producing more widespread damaging gusts and have the potential for tornadoes," said the National Weather Service.

"The storm prediction center acknowledges this threat with a moderate risk of severe weather along the coastal Carolinas which includes the outer banks. Of course damaging winds are also expected as a squall line will likely develop," the center added.

Severe thunderstorms have been forecast for the Carolinas.

The National Weather Service issued winter storm warnings that stretched from Arkansas up the Ohio River to New York and on to Maine.

The storm damaged buildings in Louisiana and Alabama on Tuesday and snow covered roads in southern Illinois and southern Indiana early Wednesday, according to the Associated Press.

According to the AP report, three people were killed and several were injured.

The storm has also affected holiday traveling. According to flight tracker FlightAware.com, more than 325 flights around the U.S. were canceled as of Wednesday morning.
