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.

According to a 5 a.m. ET advisory from the National Hurricane Center on Aug. 20, Erin is located about 455 miles south-southeast of Cape Hatteras, North Carolina, with maximum sustained winds near 100 mph with higher gusts.

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."
