stay in your basement. if you don't have one, go in a room on the 1st floor with no windows... maybe a bathroom or closet. keep a portable radio with you so you can listen to the local news and know what's going on.
There's a one out of a five-hundred chance you'll get hit, it first has to reach the ground which if you don't live on a hill you should be fine. Although you should go to the lowest floor in-case windows break from the wind, again very unlikely. But get away from glass, and get low. Hope this helps... :)
Praying is a great idea. Also, prepare yourself a bag of things to pass the time while you are taking cover. Have your iPod charged up, put a Bible, some other things to read, a deck of cards, some snacks, & a water bottle in there. Have a favorite blanket to hide under. These things all help my kids calm down, & by the time they think about the storm, it's all done.
This is an old post- but you never know who comes to see these so, here it goes anyhow. I grew up in Oklahoma, so here are a few practical things you can do. Nothing against religious beliefs or faith, but some actual things you can do are also helpful. The safest place is in a storm shelter or basement. If that isn't available, go to a central room in your home, lowest level, preferably a room with little or no windows or glass. Put on a helmet- yes a bicycle helmet. Put on a winter coat. Make sure you have on shoes and socks. Put pets in carriers and bring them in with you. Wrap your children in as many layers as you can. Get under a mattress, pillows or anything else that comes to mind that seems to put more layers between you and flying debris.
a smart thing to do is go to a basement now i don't have a basement but go to the middle of your house our stairs in the middle so we go in the closet under the stairs for strong tornadoes and in our area there is a strong possibility for tornadoes so we go in the laundry room and cover up all bundled and i pray for god to keep us safe
