(3:30am EST) Tropical storm Isaac has caused another cruise line to alter itineraries in the Eastern Caribbean this week as the storm slowly grows in strength and makes way towards the Dominican Republic, Haiti, Cuba and could threaten the United States by early next week.

Here are the lines affected as of right now:

Carnival Cruise Lines:

Carnival Ecstasy will cancel its call to Half-Moon Cay on 8/26 and go to Freeport, Bahamas on 8/26 instead.

Carnival Valor will skip Curacao and visit Nassau, Bahamas instead.

Carnival Dream will skip Nassua and visit Grand Turk instead.

Carnival Destiny will reverse the days for Grand Cayman and Ocho Rios.

Given Tropical Storm Isaac’s current location and projected path, Majesty of the Seas and Monarch of the Seas will not call on CocoCay, Bahamas, this weekend.

The said, “We encourage guests sailing on Allure of the Seas this Sunday, August 26, and Majesty of the Seas and Monarch of the Seas on Monday, August 27, to continue to monitor this website for any additional update.”

Norwegian Cruise Lines

Norwegian Sky is departing Miami on Friday, canceling the Great Stirrup Cay call on Sunday and spending the day at sea.

Norwegian Gem will depart New York as scheduled on Saturday to the Bahamas & Florida. The ship will change the order of its ports, calling on Great Stirrup Cay on Tuesday, Nassau on Wednesday and Port Canaveral on Thursday.

Norwegian Dawn will depart Boston as scheduled today to Bermuda. In order to maximize guests’ time ashore, the ship will arrive at 8 am on Sunday, three hours earlier than scheduled. Depending on the path of the storm, the ship may need to depart Bermuda earlier than schedule, depending on the path of Tropical Depression Joyce.

All the cruise lines recommend that if you have a sailing planned to closely monitor their respected websites.
