Hurricane Erin churns offshore, triggers evacuations and dangerous surf in North Carolina

Hurricane Erin, a powerful Category 4 storm with 130 mph winds, isn?t expected to make U.S. landfall ? but it?s already creating dangerous conditions along the Atlantic coast. From towering waves up to 15 feet to double red flag warnings keeping swimmers out of the water, North Carolina?s Outer Banks are on high alert. More than 1,000 people have evacuated ahead of the storm, with officials warning of flooding threats made worse by an upcoming new moon and high tides.
