Hurricane Erin is marching north, lashing North Carolina's Outer Banks with rough waves and coastal flooding, and bringing a threat of dangerous waves and potentially deadly rip currents to the East Coast. Due to the high surf and rip current risk, New York City is extending its swimming ban.

Hurricane Erin has begun to track into the open ocean and away from the North Carolina, but storm surge warnings remain in place for parts of the state and the storms effects are still expected to be felt along the East Coast.

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."
