You seem well set up for the short term. However you have pointed out that once you have eaten your way through the supplies you are undecided what you will do next.

You can solidify and increase your short term plan by fortifying the locations some more, and adding more supplies. Work out just how long you could survive from each location on it's own (worst case) and add all of them together for the best case timeline .

If you think that the disaster will only last for that time , then you are done. If however you think it will go on for much longer, then you need to plan something more self-sustaining. But get the short term sorted first.
