UPDATE, 1:16 p.m.
After cancelling morning flights to and from Louis Armstrong International due to icy conditions, runways have officially been reopened, according to a release.
Airlines were notified they could resume normal operations beginning at noon. Travelers are urged to check any scheduled flights directly with airlines, as times may have changed.
The airport has also advised that officials will continue to monitor the runway conditions as another freeze is expected for the area Wednesday evening into Thursday morning.
All vehicle traffic has been diverted to the bottom arrivals ramp, as the elevated surface has ice accumulation, the release said.
Louis Armstrong International Airport has closed its runways Wednesday morning due to icy conditions, the airport announced.
Airlines have cancelled morning flights to and from New Orleans, and the conditions will continue to be monitored.
"We will continue to monitor the runway surface conditions and will reopen the runways only when it is safe to do so," read a statement.
Record cold as low as 20 degrees in some areas of New Orleans and freezing rain made for treacherous conditions on many area roadways in the early morning.
It was really cold – historically cold, in fact – Wednesday morning in southeast Louisiana.
The airport had posted previously that there have already been several cancellations and delays throughout the morning, to "check directly with your airline before heading to the airport."
There has been no indication that the airport itself would close, although many roads, interstates and bridges remain closed amid the icy conditions.
Flights at Baton Rouge Metro Airport were also being impacted by the weather. On Wednesday, most flights in and out of Baton Rouge were canceled. At 11:30 a.m., a few flights later in the day were still scheduled. The airport advised travelers to check with their airline for the latest information.
The right, northbound lane of the Causeway has reopened, officials said, as well as the left, southbound lane.
The interstates across southeast Louisiana are blanketed by ice Wednesday morning.
