The 19th named storm this season is churning in the Caribbean and the cruise industry in South Florida is expecting to see some changes over the next few days.

As of Wednesday morning, Hurricane Sandy was heading towards Jamaica.

Several cruise lines are making changes to their itineraries as a result.

Royal Caribbean's Allure of the Seas, which cruises out of Port Everglades, will skip Wednesday's stop in Jamaica and spend an extra day at sea.

Carnival Valor, which cruises out of Miami, will skip stops in Jamaica and the Grand Cayman Islands. It will make stops in Mexico instead.

Carnival Pride, which cruises out of Baltimore, Md. and Carnival Glory, which cruises out of Norfolk, Va. have also made changes.

Norwegian Pearl will now call in Cozumel on Wednesday, and Costa Maya on Thursday, returning as scheduled to Miami on Saturday.

Norwegian Jewel will now call in Freeport, Bahamas on Wednesday, and Charleston, SC on Friday, returning to New York as scheduled on Sunday.

Norwegian Sky will cancel its call to Great Stirrup Cay on Thursday and will spend the day at sea.

Each year, about 7.5 million visitors come through Port Everglades and Port Miami on about 70 different ships.

More changes could come as the storm moves through the Caribbean. Check with the cruise line if you are concerned about a trip you're taking this week.
