So I recently finished moving into my beautiful new home. First time homeowner, we did all the things I could think to do to help secure the house. It's got it's own well, it's on a hill, has a nice foundation, etc.

As time goes on, I will add a backup generator to the well pump, some 50 gallon drums for storing water, etc.

My concern is that there is one tidbit of information I found:
York Haven-area historical tornado activity is slightly above Pennsylvania state average. It is 34% greater than the overall U.S. average.

Well, my basement is unfinished with superior walls up. It has several windows, making it an inadequate storm cellar. Now I'm thinking I can build a concrete cinder block safe room down there to help, but I'm curious to see what other suggestions you all have.
