A tropical storm warning has been issued for North Carolina as Hurricane Erin churns up the east coast of the U.S. as a Category 2 storm.

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.

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.
