Forecasters say Tropical Storm Erin, which formed in the eastern Atlantic Ocean on Monday, is expected to become the Atlantic's first hurricane of the season. The storm formed just west of the Cabo Verde islands, off the western coast of Africa, and was moving west, the U.S. National Hurricane Center in Miami said.

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