my biggest fear is that I will not be where my supplies are (home) when it happens and the roads will not be passible. You know Murphy's Law. If it can go wrong, it will. I live in the country so must drive into town to buy supplies, see doctor, visit friends, etc. Murphy says that is when it will happen, when I'm somewhere else, so all of my preparations will be for naught. The problem will then be how to get home where my supplies are.
