Why a Crawl Space Can be Dangerous During a Tornado

Through my years as a meteorologist, I’ve had people tell me they seek shelter from tornadoes in the crawl space of their home. This can be a tragic move. If your home has a typical concrete block foundation with nothing holding the blocks together other than a thin layer of mortar, it’s simply too dangerous to hide from tornadoes in your crawl space.   Seeking shelter in a sturdy building in a small space such as a closet or bathroom away from outside walls or in an engineered storm shelter is much better.  Watch the video to see why…

  1. You just discounted all crawl spaces based on one design. There are many different types of crawl spaces. It would be better to explore how each different design works. Not just categorically reject crawl spaces based on one design.

  2. Thanks for your comment. In the video, I specifically referenced the unreinforced concrete block type of foundation that is common across the state of Tennessee. Other foundations, such as those made of poured concrete or block style which is reinforced with rebar and back-filled with concrete would be a much better option.
