The National Hurricane Center is monitoring thunderstorms in the Atlantic that have a 50 percent chance of turning into a tropical depression or storm within the next 48 hours, the center reported Thursday.
Chances of formation within the next five days are up to 70 percent, officials said.
Data collected from the Air Force Reserve Hurricane Hunter expected some development during the next day or so, and a tropical depression or tropical storm could still form while the system moves west-northwestward at about 20 mph across the Lesser Antilles.
Airlines and cruise ship companies were monitoring the progress of a tropical disturbance on Thursday.
The Associated Press reported that a spokesperson for Carnival Cruise Lines said it had one ship whose itinerary would be slightly modified to steer clear of the system’s predicted path.
