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.

Tropical Storm Erin is tracking west over the open Atlantic Ocean on Tuesday and forecasters expect it to become the first hurricane of the Atlantic season this week.

The air feels tropical in North Carolina, but tropical activity is ramping up in the Atlantic Ocean were Erin may become a hurricane. Erin may also could impact the Leeward Islands and Puerto Rico depending on how far north the storm tracks.
