Cape Hatteras, N.C. – Tropical Storm Arthur moved out to sea Monday after dumping heavy rain on North Carolina as forecasters warned that the first named storm of the Atlantic hurricane season could continue to whip dangerous surf and rip currents for another day or more along the U.S. East Coast.

The storm represented another early start for the Atlantic hurricane season. Arthur formed Saturday in waters off Florida, marking the sixth straight year that a named storm has developed before June 1.

By late Monday, storm watches and warnings that had been in effect for parts of the North Carolina coast were canceled.
