Two of the Carnival ships are diverting to New Orleans, where they will let people off if they don't want to wait around until it's safe to dock in Texas.
Mayor James Yarbrough said during a news conference Friday that Hurricane Harvey is expected to flood downtown streets.
The Carnival Valor and Carnival Freedom will make a brief stop, where passengers can choose to end their cruise, but are being asked to stay onboard and sail back to Galveston once the port reopens.
Currently, the Carnival Freedom and Carnival Valor are at sea in the middle of their voyage.
Thousands of passengers on several Carnival cruise ships are stranded and unable to return to the Galveston, Texas port after Hurricane Harvey.
Port authority representative Roger R. Quiroga said passengers or crew members facing medical emergencies while on a ship waiting out the storm will be serviced by a medical helicopter that can reach them if needed. A separate Carnival ship in Cozumel, Mexico, which was scheduled to depart for.
Royal Caribbean's Anthem of the Seas did sail into a storm off the Atlantic coast previous year, forcing the ship to turn around, and subjecting the passengers to the consequences of high wind and waves. It is expected to remain closed until the storm has passed and a port assessment has been completed. The ship is currently docked in Cozumel and will now stay overnight there.
Carnival and Royal Caribbean cruise lines are both monitoring the storm to figure out the best course of action between now and the weekend. Again, all of this is contingent upon the Port of Galveston actually reopening. Cruise details will be finalized once we have confirmed our arrival into Galveston. Guests who sail on modified voyages will receive a pro-rated refund equal to the number of cruise days they missed.
Right now, Carnival tells us their customers should sign up for text messages alerts to keep up with updates from the company.
With the Port of Galveston closed to all marine traffic, two Carnival Cruise Line ships scheduled to arrive Saturday are being redirected to New Orleans, according to a company spokeswoman.
