"The alternative to community shelters is for individuals to put shelters in their homes. One such shelter is called a safe room, typically a concrete-reinforced master closet or laundry room, said Harrington.
Another alternative is a poured concrete, above-ground structure in the shape of a vault that is often put in a garage, she said. Those structures typically cost as little as $2,000 and were growing in popularity even before the recent tornado, she said.
"It's an absolutely viable product right now," Harrington said."
