Hurricane Erin, now a Category 2 hurricane, won't make landfall on the U.S. East Coast, but it will impact residents and visitors at North Carolina's Outer Banks.

People in the Outer Banks should shelter in place, authorities said. Meanwhile, life-threatening rip currents are likely at beaches along the East Coast, according to forecasters.

North Carolina expects coastal flooding from massive waves, tropical-storm-force winds and tidal and storm surges for much of the state shoreline, especially the Outer Banks, as well as life-threatening rip currents for most of the week, Stein said, adding, "No one should be in the ocean."
