Storms systems brought tornadoes to the East Coast -- killing four in Virginia -- heavy snow that canceled hundreds of flights in the Midwest and power outages that left hundreds of thousands across several states in the dark.

In Virginia, the tiny town of Waverly took the brunt of the storm. The Virginia State Police spokeswoman Corinne Geller said a 2-year-old child and two men, ages 50 and 26, were killed there during the storm. Their bodies were found about 300 yards from their mobile home.
At least five structures were damaged in the town of approximately 2,000 and roads leading into town had to be closed because of downed trees and debris tossed by winds gusting to 60 mph, Geller said.
In Appomattox County, a funnel cloud left an 8- to 10-mile path of destruction, injuring seven people and killing one man, state police said.
At least 15 structures were destroyed and 25 injuries were reported when the storm passed through Essex County and the town of Tappahannock, about 45 miles northeast of Richmond, state police said. The injuries ranged from minor to serious, but there were no confirmed fatalities.
In Waverly, witnesses said the storm swept through with little warning.
Timothy Williams said a friend had just come by to take his new car for a drive when the storm hit.
"It picked the car right off the ground, and put it right back on the ground," said Williams, 44. He said they remained in the car until the storm passed.
The storm blew down electrical wires "in a big ball of fire, thrashing all about each other," Williams said. He said they both escaped shaken but uninjured.
In South Carolina, Darlington County Corner Todd Hardee said in a statement that Michael Gaines Sr., 58, had stopped on a road near his home Wednesday to remove debris from the road when a pine tree fell on him. Sheriff Wayne Byrd said the victim was being a good Samaritan when he was killed.
