Hurricane Irene is playing havoc with cruise shipping.

The first hurricane of 2011 is steadily increasing strength and heading for the U.S. East Coast – maybe even Miami.

The hurricane has forced Carnival and Royal Caribbean to alter itineraries for 12 of their ships because Irene is bearing down on popular cruise ports like the Grand Turks.

MSNBC reported this morning these changes to cruise itinerates:

- Carnival Pride, which left Baltimore on Sunday for a week-long Bahamas and Florida cruise, will sail a revised route. The ship will now visit Port Canaveral (Tuesday, instead of Wednesday) and Freeport (Wednesday), after which the line will determine the remainder of the itinerary based on Irene's projected path.

- Carnival Triumph, which sailed from New Orleans on Saturday for a week-long Bahamas and Florida cruise, is swapping its Bahamas calls for visits to Western Caribbean ports. The new route includes stops in Key West (Tuesday, as planned), Cozumel (Wednesday) and Progreso (Thursday).

- Carnival Destiny, which departed Miami on Monday for a five-night cruise to Grand Turk, Half Moon Cay and Nassau, will instead visit Key West (Tuesday), Cozumel (Wednesday) and Costa Maya (Thursday).

- Carnival Conquest, which left Galveston on Sunday for a week-long Bahamas and Florida cruise, will now sail a Western Caribbean itinerary. The new route calls for visits to Costa Maya (Wednesday), Cozumel (Thursday) and Progreso (Friday).

- Carnival Victory had to cancel Monday's call at St. Thomas and is proceeding to Barbados for its scheduled call on Wednesday. Spokesman Vance Gulliksen said the line is still evaluating the remainder of the itinerary. Victory is on a seven-night cruise from San Juan.

- Carnival Liberty, in the midst of a seven-night Eastern Caribbean cruise from Miami, is stopping at Grand Turk Monday instead of spending the day at sea as originally planned. The line is evaluating the remainder of the itinerary.

- Carnival Miracle, which embarked from New York Thursday on an eight-night Eastern Caribbean cruise, is sailing an altered itinerary. Instead of visiting San Juan, St. Thomas and Grand Turk, the ship is now calling on Grand Turk (Monday) and Half Moon Cay (Tuesday).

- Royal Caribbean has reversed the itinerary for Oasis of the Seas, which left Fort Lauderdale on Saturday for a week-long Western Caribbean cruise. The ship is now visiting Cozumel on Monday; spending Tuesday at sea; calling on Falmouth, Jamaica on Wednesday; and visiting Labadee, the line's private peninsula in Haiti, on Thursday. Oasis will spend Friday at sea before returning to Fort Lauderdale on Saturday as scheduled.

- Freedom of the Seas, which left Sunday from Port Canaveral on a week-long Western Caribbean cruise, is sailing a reversed itinerary. The ship is now calling on Cozumel (Tuesday), Grand Cayman (Wednesday), Falmouth, Jamaica (Thursday) and Labadee (Friday).

- Oasis' sister ship, Allure of the Seas, is visiting all the ports originally scheduled on its week-long Caribbean cruise, but in a slightly different order. The ship will visit Nassau, Bahamas on Saturday (August 27) instead of Monday (August 22). Visits to St. Thomas (Wednesday) and St. Maarten (Thursday) will take place as planned.

- Royal Caribbean has scrambled the order for Serenade of the Seas' seven-night Southern Caribbean cruise, which left from San Juan, Puerto Rico on Sunday. The ship is now visiting Aruba (Tuesday), Curacao (Wednesday), St. Kitts (Friday) and St. Thomas (Saturday).
