Dangerous ice storm, heavy snowfall and potential travel woes and power outages expected in the Southeast - CNN

Snow was falling across southeastern Virginia and was forecast to gradually change over to freezing rain.

As of Sunday morning, about 200,000 customers were without power in the southeast, including over 100,000 in Georgia and more than 40,000 in each of Florida and South Carolina, according to the website PowerOutage.US.

As much as a foot of snow could fall near the edge of the Blue Ridge escarpment in Greenville and as much as 20 inches of snow could accumulate above 4,000 feet of elevation in that area.

Raleigh is expected to get up to 2 inches of snow and maybe a quarter-inch of ice, forecasters said.

The NWS is warning ice accumulations will become very dangerous along and east of I-85 including Spartanburg, South Carolina, all the way up to Salisbury, North Carolina.

Heavy snow will is also possible in western Virginia.

The governors of Georgia, North Carolina, South Carolina and Virginia declared states of emergency, allowing resources to be positioned ahead of the storm's arrival.

Parts of northern and central Georgia could also see powerful winds Sunday, the National Weather Service in Atlanta said.

"7 to 10 inches is possible, but over a foot is not out of the question where heavier bands form."

Snowfall intensity in the region may be heavy enough to evade significant icing, but NWS Baltimore warned untreated surfaces may still lead to dangerous travel conditions where ice accumulates.

The majority of accumulating snowfall will occur Sunday afternoon through Monday morning.

Interior cities such as Charleston, Pittsburgh, Buffalo, Syracuse and Burlington, Vermont, will see the heaviest snow.
