"She said there was almost no water in the store and the canned food was almost gone. I don't know if that's just a localized problem or not."
I have a few students in my criminal justice class that has said the same thing. They can't find any bottled water in Houston.
The individual stores ran out, but there are distribution centers all around town (Randalls has a huge one down the street from me). They are already restocking this morning, but I"m sure they will be out by this afternoon.
Buy a new clean trash can and liners, put liners in the can and fill with water. Fill your tubs. Fill your washer. Fill plastic containers and put in your freezer which will keep it cooler longer after the power goes, then you can drink it. Remember to run your dishwasher before power goes out if it's full. Luckily I am a homebrewer and have about 10 5 gallon kegs I am filling with water. Improvise, don't depend on buying water.
And for fun...

A: He really doesn't care how people get out of New Orleans- as long as
they get out.
