I've got pneumonia, so I'm keeping this short. Go to www.monolithicdome.com & see buildings which have survived any weather you'll encounter in this or any other country. These buildings, depending on how fancy you want to get, can be built in one to three weeks. Build it for a garage & use it for a storm shelter. Or build your home this way & you won't need a shelter. Good luck, and if you get to talk with David South or Gary, tell them Brian from Lake Charles LA. said hello. Cheers, Brian.
