Long Island and New York City airports shut at 10 p.m.

There will be no flights leaving New York City airports after 10 p.m. tonight, the Port Authority said early Saturday evening. 

Long Island MacArthur Airport closed at 6 p.m. Saturday, and all commercial flights have been canceled until Monday, an airport spokeswoman said.

General aviation flights will able to use the airport until it closes, said Catherine Green, the airport's communications director.

Arriving flights at area airports were canceled earlier in the day.

LIRR already began running its last trains on its 11 lines Friday night, and will continue to do so Saturday morning and early afternoon. The LIRR is completely shut down through at least Monday, and possibly much later.

"It's going to be an extremely difficult situation," MTA chairman Jay Walder said of the recovery, which will be aided by State helicopters surveying the expected flooding rail yards and downed trees on tracks and electrical lines.

Other transportation providers will similarly shut down for the storm. Suffolk County Transit will suspend all buses by 8 p.m. Saturday through at least Monday. Amtrak suspended service in the Northeast and south of Washington, D.C., beginning Friday. The Hamptons Jitney has suspended its buses beginning Saturday evening into Sunday evening. The Bridgeport & Port Jefferson Ferry will not run Sunday.

Area bridges will also likely be closed to traffic if winds become too severe. Flooding could also cause some tunnels to close, officials said.

Those traveling by air could also be affected by the storm. Airlines including American, JetBlue and Southwest, combined, canceled hundreds of flights along the East Coast. Port Authority officials said they expected JFK and LaGuardia airports to remain open, and well-stocked with supplies for stranded passengers.
