My daycare is in my basement so we just carry on as it is the safest place to be anyway. I also have large, full-sized windows on my basement so power loss really isn't a factor either. The only thing that changes in severe weather for me is that I have my OWN kids come down to the basement too.

If there was an actual tornado coming down on us we would all go to my cold cellar, which is also off of my basement. My cold cellar has four cement block walls and a cement pad ceiling so it is the safest place in the house.
