I should have a lot of ideas being in Panama City Fl. we just went 5 days without faucet water and 8 days without electricity, and we were the lucky ones!
I agree on a small generator, you can size it to run the fridge and a microwave or a two burner stove. If you have a freezer and need to save the food, make sure it has the power needed.
I don't know your need for heat, that could be a big one, you don't want pipes to freeze, again a bigger generator. You need fuel for the generator, the first few days fuel was not available.
People waited 3 and 4 hours in line for gas when it came in.
For water we had a bathtub filled with water, although we were late filling it and it was a bit dirty. We sat in our second tub with a 3 gallon bucket of water and used that to wash and rinse with, the second day my wife said, we need to put the pails in the sun all day before we bath, yes, the first bath was what I might call very exhilarating! :-)
About the 3rd day, ice and water bottles were starting to be distributed, very much appreciated.
On the fourth day we had MRE's and groups were making food for people.
A propane stove would be reasonable for cooking.
I still don't have cable internet, and they don't have any estimate, could be a month or more.
I bought an AT&T phone and I'm tethering my laptop to it. My Verizon phone has very poor service, and none for the first 4 or 5 days.
