WEST PALM BEACH, Fla. — WPTV First Alert Weather meteorologists continue to track a tropical wave moving through the Atlantic Ocean, which will head into the Caribbean Sea this week.

The disturbance, called Invest 98-L, is located a few hundred miles east of the Windward Islands and continues to show signs of organization.

Additional development is expected, and a tropical depression is likely to form within the next few days as the system moves westward to west-northwestward at 15 to 20 mph across the eastern and central Caribbean Sea.

At 10 p.m. Tuesday, the system has a 60% chance to form in the next two days and 90% in the next five days.

"Once it gets into the Caribbean, it'll head toward Jamaica, then computer models diverge a bit," WPTV First Alert Meteorologist John Gerard said. "Some turn it north to the eastern Gulf of Mexico later next week, some take it farther west."

Meteorologists will monitor this should it develop. Any potential threat to the U.S. coastline would be mid to late next week.

More Florida hurricane landfalls occur in October than in any other month, so it is the peak of the season for Floridians.
