Hi, I think that in case anything like that happens we should go to high ground. We should also save up water and food and balance our meals everyday, and wait for the situation to end. I also think that the safety of others are important, so I think ever in case there is a flood that we should also evacuate other people to high places and share our food with those with need. We should also take shelter, and that shelter should be close to another shelter, in case that shelter we would be currently staying in would be destroyed. This is what I would do if we were in the face of extreme weather like this. Have a good day!
