When Rita knocked out our power last year, everyone in the neighborhood was running generators. One generator cancelled out the noise from the others.
The first day and a half, we had no generator and had to use inverters and car batteries... THAT SUCKED!!!!!!!!!!
If you can order a generator ahead of time, and stash it in the garage, you will save yourself a huge pain in the rear. Gasoline also ran out where I live. I had to drive 50 miles to fill up the jeep, and five 5gallon gas cans. The lines were terrible. Gas ahead of time wouldn't be a bad idea either.
We made it through with only losing a couple of bristle starfish. The tanks got too hot. The inside of the house was 100 degrees for five days. Now I have 2 liter bottles frozen in the deep freeze, just in case.
I hope we don't get one again this year.
Best of luck...
