Did I do the right thing here?

There was an f0 tornado approaching me. I was in my house. When I found out I rushed to the basement. And I went into our concrete storage room. On 1 side there was. I wood wall. Another wood wall. A brick wall. Then a concrete wall. On the other side. It was just under ground. Did I do the right thing? I brought no helmets/protection at all. Just the walls.
