No, I'm not prepared for an emergency such as this. I think people in the area where I live are not prepared either. We have experienced flood in Poland many times, the biggest one since 150 years was on May 2010. Many people were affected by massive flood. Luckily, there was enough food for everybody, they can transport it from other parts of Europe. People don't think about any food storage rather about where to run away with the most valuable stuff.
Mother nature! We build something for many years she can damage it in a couple of minutes let alone people who are killed.
