A ferocious storm system that kicked up tornadoes, flash floods and hail as big as softballs rampaged across the southern U.S. over the weekend, killing at least 45 people across six states. North Carolina was the hit the hardest. North Carolina Gov. Beverly Perdue said she's never seen anything like the destruction caused by the storm system that has claimed at least 21 lives statewide.
