Tropical Storm Erin may near Puerto Rico and the Dominican Republic before likely turning north as a hurricane, sparing the U.S.

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

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.
