Multiple warnings were in effect along the East Coast on Wednesday, as officials warned of a "life-threatening" situation.

Weather conditions are expected to deteriorate along the coast of North Carolina on Aug. 20 due to Hurricane Erin, according to the NHC.

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."
