One of the problems that can happen with a underground storm shelter is the door being blocked by debris like tree limbs, cars and other vehicles; big pieces of debris that might be too heavy to move. My advise is to put a large 4,000 pound or greater jack in the shelter with some big wood blocks. A heavy crow bar, axe, etc also.

They make reinforced steel above ground shelters that can be built into your home and bolt onto a cement slab:

Heck yea!! That’s the ticket there!

Did you hear about the folks at the Full Moon BBQ on Mcfarland in Tuscaloosa? They were eating a late lunch, or early dinner and having a few beers when they saw this thing coming straight at them. About 15 customers and staff ran to the cooler. The structure was flattened, I mean gone, and the cooler saved them.

I’d go for an underground shelter + jack and blocks. Anything above ground is much more susceptible to impact damage and would have stuff piling up against it more than a ground door. Think what would happen if a semi came flying into that above ground shelter at 200+ mph.
