Hurricane Erin is marching north and is set to bring life-threatening rip currents, destructive waves, coastal flooding and possibly beach erosion to much of the East Coast. The conditions will last through Thursday before improving later on Friday and into Saturday.

Hurricane Erin began strengthening again Wednesday as it crept closer to the mid-Atlantic coast, its outer bands brushing North Carolina’s Outer Banks as beaches closed across much of the U.S. East Coast.

Hurricane Erin's path will not bring its strongest winds ashore. However, it continues to grow in size, and its impacts from high surf, rip currents and coastal flooding are already increasing along parts of the East Coast.
