Carnival Valor and Carnival Freedom are now keeping a safe distance from the storm as they make their way back to Galveston.
Even if the ships make it to port, some passengers may not be able to make it to Galveston if roads are flooded in the low-lying areas leading to the port city.
Carnival Cruise Line has been one of the main cruise lines impacted by the strong Hurricane Harvey. Carnival Breeze is spending more time in Cozumel so by the time it gets back to Galveston it could reopen, if not the ship will wait at sea until it does.
A third Carnival ship, Breeze, was scheduled to return to Galveston on Sunday.
By Friday night, Hurricane Harvey was classified as a Category 4 storm.
With 20,000 vacationers waiting at sea on cruise ships and beach parks shuttered for the weekend, Galveston is hunkering down for the storm.
You can also follow the cruise lines on Facebook and Twitter for possible updates regarding for your trip.
