All flights at Miami International Airport have been cancelled until further notice.
No flights are expected to depart before Monday at the earliest as Miami, and Florida, prepare for the impact of Hurricane Irma.
Residents of mainland Florida have been advised to brace for the impact of the Hurricane Irma, as conditions in the south of the state deteriorate.
The category four storm with winds up to 130mph has moved away from the Florida Keys and should make landfall on the west coast within hours.
More than six million residents have been advised to evacuate.
Around one million are currently believed to be without power.
Irma has already devastated parts of the Caribbean with at least 25 deaths.
Cities such as Tampa and St Petersburg lie in the path of the storm.
The Tampa Bay area, with a population of about three million, has not been hit by a major hurricane since 1921.
