Hi neighbor, I'm in Flint. We don't usually get direct hits either, but when we do, they are doozies. I'm worried about Fenton, they had an F1 and a lot of "almost tornadoes" last year, I hope this year isn't worse.
I'm sorry to hear you are basement-less. Do you have pets? If so, pay them some special attention, they really do know what's about to happen with the weather. If all else fails and you are in one of the areas that has drainage ditches, and you really feel that you won't be safe in the house, run with a blanket to the ditch. My grandmother did that a few times when she lived in Beecher, and she lived through their big tornado.
Otherwise, get a packing quilt, and keep it in an interior room with no windows. The quilt might help keep you safe from flying things if you have to duck and cover. I throw a packing quilt over my kids every time we have to go to the basement.
Or you can come to my house during warnings, LOL, I have a big basement.
