The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome.

Hurricane Erin, now a Category 2 hurricane, won't make landfall on the U.S. East Coast, but it will impact residents and visitors at North Carolina's Outer Banks.

The National Hurricane Center is tracking two areas of interest in the eastern Atlantic for possible development. This is in addition to Hurricane Erin, which is anticipated to remain offshore of the Eastern U.S. coast. The tropical wave located over the central tropical Atlantic is producing disorganized showers and thunderstorms.

Forecasters are tracking three systems in the Atlantic basin, including one with a medium chance of becoming a tropical depression later this week.

Hurricane Erin has not fully moved past North Carolina. However, storm is no longer tracking north-northwest more eastward.

Hurricane Erin stays offshore but brings rip currents, high surf and gusty winds to East Coast beaches through Friday. Follow Newsweek's live blog.
