Erin’s long-range track was still the subject of much speculation, with it being too soon to rule out threats to the U.S. Many forecast models suggest the storm, which could become a Category 3 hurricane by late this week, will track westward but then turn to the north and then northeast, keeping it off the U.S. East Coast.

Tropical Storm Erin formed in the eastern Atlantic Ocean on Monday, forecasters said. The storm was expected to strengthen later in the week and could become the Atlantic's first hurricane of the season.

A system now forming in Atlantic off Africa could gain hurricane strength soon, but may not threaten the U.S. East Coast
