Two more tropical systems trail Hurricane Erin, which is following a projected course that brushes past the East Coast without making landfall.

Meteorologists are closely tracking the projected path and forecast of Hurricane Erin, which is the first hurricane to develop over the Atlantic this year.

Hurricane Erin is expected to grow in size and strength as it moves north through the Atlantic this week. Forecasters expect it to pass well offshore of North Carolina on Wednesday and Thursday, but say it likely will cause coastal flooding and erosion, along with dangerous rip currents.

Category 2 Hurricane Erin moved northwest at 7 mph about 720 miles to the southeast of Cape Hatteras on Tuesday morning. Still forecast to be turning away from the shoreline of North Carolina on Thursday,

Hurricane Erin is moving east of the U.S. coast and will bring strong waves and rip currents to Florida's east coast – and it comes as the National Hurricane Center is eyeing two more tropical waves in the Atlantic.

"We cannot put this more bluntly: we now EXPECT there will be times over the next week that N.C .12 becomes impassable due to significant ocean overwash," OBX transportation officials said.
