The National Hurricane Center is tracking two systems in the Atlantic basin, including a new one moving into the Gulf.

Forecasters say Erin will likely become a hurricane in a couple of days, but it's still too early to determine what sort of impacts the storm could have, if any, on the U.S. East Coast.

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.
