Hurricane Earl has caused several ships to change itineraries in order to avoid the storm. Some of the most popular Islands in the Caribbean like St. Maarten and St. Thomas are too close to the projected path of Hurricane Earl. So in the interest of safety and not ruining vacations the cruiselines have altered some itineraries of ships currently cruising the Caribbean.
Carnival Victory, Carnival Pride, Carnival Dream, Norwegian Epic, Enchantment of the Seas, Oasis of the Seas, and possibly the Norwegian Dawn will have their itineraries modified due to the storm. You can see all the details on these changes on the CruiseSource.us Hurricane Cruise Tracker page.
