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.

Dangerous rip currents are expected along the U.S. East Coast as Hurricane Erin grows in size this week, the National Hurricane Center said Tuesday.

Powerful Hurricane Erin is expected to bring high seas, big rip currents, and rough surf as it moves between the United States and Bermuda.
