The first thing that people are looking for right now is safety. This isn’t over yet and there are still people in substantial danger. So people want their leaders to do what it takes to get them to safety and make sure that the places they’re taking refuge are safe places.
Once the immediate danger is past then there is going to be a lot of concern for getting to a stable situation, back home if possible but out of the shelters and back to something more like a normal life. In an event like this, where entire neighborhoods have been catastrophically flooded, that’s going to be tough.
