Airlines are canceling hundreds of flights as Hurricane Matthew sweeps along the Florida coast.
The Fort Lauderdale airport shut down on Thursday morning, and further north the Orlando airport expected to do the same by nighttime.
McCarran International Airport is reporting 13 cancelled flights headed to and from airports in Miami, Fort Lauderdale and Orlando aboard American Airlines, Frontier Airlines, Southwest Airlines, JetBlue and Spirit Airlines, airport spokeswoman Christine Crews said.
By midday, flight-tracking service FlightAware.com reported that nearly 1,500 flights within the U.S. had been scrapped, with the largest numbers at Fort Lauderdale and Miami. American Airlines, which has a major hub in Miami, was the hardest-hit carrier, followed by Southwest Airlines and JetBlue Airways.
FlightAware says airlines have already canceled nearly 1,300 flights scheduled for Friday.
Airlines often cancel flights before storms hit to prevent passengers from being stranded at airports and to keep their planes in position to recover after the bad weather passes.
Disney World, Universal and SeaWorld announced Thursday morning they are shutting down as the hurricane barrels toward Florida with 140 mph winds.
