With Hurricane Gustav expected to make landfall in the next 24 hours, Louis Armstrong New Orleans International Airport is about to close to all commercial flights.

According to the airport Web site, commercial flights will be suspended at 6 p.m. today (that’s about half an hour from now).

However, Flightstats, citing a notice from the Federal Aviation Administration, says the airport is already closed.

Neither of the sources has said when the airport might reopen.

Here is what the full text of the airport notice issued at 3:30 p.m. today:

The Louis Armstrong New Orleans International Airport is operating under a Hurricane Warning.

Commercial flights will continue until 6:00 p.m. today although some air carriers have ceased operations already. All passengers scheduled on regular passenger flights were accommodated by their airlines and will depart Armstrong International on the last scheduled flights.

At this time there is no timetable for the resumption of air service at Armstrong International. That information will be released to the media and posted on the airport’s web site at www.flymsy.com when it comes available.

The best way to get out of town is by car, although some roadways — particularly I-10 — are heavily congested. Check traffic reports online before evacuating.

Good luck.
