Matthew, which caused widespread devastation in Haiti, is heading towards the Bahamas and is expected to make landfall in Florida on Thursday. The hurricane caused a large number of cruise itinerary changes.
A statement by Port Miami, the world's busiest cruise port, says:
"Cargo terminals SFCT and POMTOC will be closed Oct. 5 for ALL VESSEL AND TRUCK TRAFFIC until further notice. We encourage cruise passengers to contact the lines directly for the most up-to-date itinerary changes."
For the first time since for 14 years, Port Canaveral issued an evacuation order for all port's landside port operations.
The National Hurricane Center claimed the following:
"There is a danger of life-threatening inundation during the next 36 hours along the Florida east coast from North Palm Beach to the Sebastian Inlet."
It is not yet clear whether the ports will remain closed as Hurricane Matthew, if it does hit Florida, is expected to make landfall tomorrow.
In case the ports stay shut, the cruise ships will either have to stay at sea or head to a different port further up Eastern Seaboard.
