Howard and others.

While we aren't in New Orleans, Mississippi Public Broadcasting is now
pretty much in full storm coverage since we are the state-wide evacuation
announcement network for Mississippi.

You can find our stream at

http://www.mpbonline.org

Go to the radio page, and you should see it.

You might also try http://www.wrbh.org. That's the open channel FM radio
reading service which is in New Orleans. They may have some coverage as
well.

I'm sure there are other stations in New Orleans, I'm just not familiar with
them.
