WEST PALM BEACH, Fla. — WPTV First Alert Weather meteorologists are tracking a tropical wave that is moving toward the Caribbean Sea, which could have an effect on South Florida's weather next week.

The disturbance, called Invest 98-L, is producing shower and thunderstorm activity near the southern Windward Islands and over adjacent waters.

The system continues to show signs of organization, and it will likely become a tropical depression within the next couple of days.

Invest 98-L is forecast to move west-northwestward across the southern Windward Islands on Wednesday and then move toward the central Caribbean Sea later this week.

As of 2 p.m Wednesday, the system has a 70% 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."

The next named storm will be called Hermine.

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.

Hurricane Fiona heads north after lashing Caribbean

Hurricane Fiona is the first major hurricane of the season and developed into a Category 4 storm as it moves away from the Bahamas.

On the forecast track, the center of Fiona will pass just to the west of Bermuda Thursday night, approach Nova Scotia on Friday, and move across Nova Scotia and into the Gulf of St. Lawrence on Saturday.

Some additional strengthening is forecast through Wednesday night, with some fluctuations in intensity possible on Thursday.

A hurricane watch and tropical storm warning are in effect for Bermuda. The storm is 650 miles southwest of Bermuda.

Hurricane-force winds extend outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 195 miles.

Storm surge will cause elevated water levels along the coast of Bermuda in areas of onshore winds beginning late Thursday. Near the coast, the surge will be accompanied by large and destructive waves.
