Anticipating some less than perfect days weather-wise, Royal Caribbean International has closed its private Bahamian island CocoCay until Sept. 4.
Royal said the safety of the 400 local employees that need to be evacuated from the island was paramount in its decision.
The line said it would update itineraries for those ships impacted by the closure at 3 p.m.
Tropical storm force winds are expected to begin in the Bahamas by Friday, according to the National Hurricane Center which is tracking Tropical Storm Dorian.
Royal said pre-purchased excursions for CocoCay guests would be refunded to their shipboard account or their charge card.
In addition, Royal said it moved three of its ships in the Caribbean to more westerly itineraries to avoid the storm.
Disney Cruise Line also changed the itinerary of its Port Canaveral-based Disney Fantasy, from an eastern Caribbean to a western Caribbean route.
Carnival Cruise Line did not announce any itinerary changes.
