Listening to Tornado Myths and Truths—What I Picked Up from “Stuff You Should Know”

Today’s weather education came not from a textbook or a lecture, but from a podcast. On a long drive, I cued up an episode from one of my all-time favorite shows, Stuff You Should Know, titled “Myths and Truths About Tornadoes.” While it wasn’t a deep dive into atmospheric science, it was packed with surprising facts, entertaining anecdotes, and just enough surface-level detail to make it a worthwhile listen. In fact, I believe the real value of episodes like this one is that they remind you: learning can be casual, unexpected, and still effective.

If you’re like me—self-taught, curious, and trying to build up a meteorological foundation—you know that professional and academic sources are essential. But podcasts like this one help broaden your context and spark new questions. Here’s what I took away from the episode.

The Trailer Park Myth: Do Tornadoes Really Target Mobile Homes?

One of the most persistent tornado myths is that they “seek out” mobile home parks. While that sounds like a dark joke, the numbers do seem to back it up—people in mobile homes are 10 to 20 times more likely to be killed in a tornado than those in houses built on permanent foundations.

But tornadoes don’t have preferences. The truth is layered in geography, construction, and how tornadoes are reported. For one, mobile homes are more likely to be completely destroyed even by lower wind speeds (say, 55 mph), while a well-built house might withstand winds up to 100 mph. These homes are also often situated in what researchers at Purdue called “transition zones”—areas between urban and rural land where tornadoes are more likely to touch down. Combine that with media bias (reporting focuses on the most dramatic damage), and it creates the impression that mobile home parks are tornado magnets.

One fascinating theory offered by host Josh Clark: could the higher static electricity in metal-based mobile homes somehow attract tornadoes? It’s unproven but an intriguing hypothesis.

The Overpass Myth: Not a Safe Haven

Another widely believed survival tip is to take shelter under an overpass. It sounds logical—thick concrete, out of the open—but in reality, it’s one of the worst places to be. Overpasses actually funnel wind and debris, creating a wind tunnel effect that increases the danger. People huddling in the wedge where the road meets the bridge face amplified wind speeds and flying debris with nowhere to go. Even if the tornado doesn’t pass directly overhead, the inflow jet alone can be deadly.

The podcast revisits a well-known video of people surviving under an overpass, but clarifies that they were lucky—not safe. That kind of footage shouldn’t be used as proof of a reliable strategy.

Breaking Windows and the Pressure Myth

If you grew up in a tornado-prone area, you probably heard that you should open your windows before a tornado hits to “equalize the pressure” and prevent your house from exploding. That’s false. It turns out tornado damage comes from wind and debris, not pressure differential. And opening your windows only wastes valuable time that you could be using to get to safety. It might even make things worse by giving the wind a better shot at ripping your roof off.

Bathtubs: Not a Universal Safe Spot

Another staple of tornado survival advice: get in the bathtub. The idea is that it’s a sturdy fixture often found in an interior room. But most modern bathtubs are just fiberglass shells—far from indestructible. The real takeaway here is location. A bathtub might be okay if it’s in a windowless, interior bathroom, but it’s no better than any other spot if it’s up against an exterior wall or under a big window.

Best practice? Get to the lowest level of your home, put as many walls between you and the outdoors as possible, and avoid glass at all costs. Closets, interior hallways, and interior bathrooms still beat the tub if they’re better positioned.

Tornadoes Avoid Cities? Not Exactly

It’s commonly believed that tornadoes “avoid” cities. That’s another illusion created by statistics. Most of the U.S. is rural, and tornadoes happen more often in open terrain simply because there’s more of it. But cities are not immune. Oklahoma City has been hit multiple times—most notably by an EF-5 in 1999 and again in 2013. Atlanta was struck in 2008 during an SEC basketball tournament. Even Miami has had tornadoes, although you’re more likely to hear “hurricane” when you think of South Florida.

Tornado Alley—and Why the U.S. Leads the World

Tornadoes occur on every continent except Antarctica, but the United States is the undisputed global leader, logging about 1,400 each year. By comparison, all of Europe only gets around 300. Why us? It has everything to do with geography. The Great Plains region—aka “Tornado Alley”—sits at the perfect crossroads of cold, dry air from Canada and warm, moist air from the Gulf of Mexico. That clash is ideal for supercell thunderstorms, the breeding ground for the most violent tornadoes.

Tornado Alley stretches from central Texas to Iowa, and from Nebraska over to western Ohio. There’s even a “Dixie Alley” in the Southeast, including parts of Georgia and Florida, that sees more fall tornadoes.

Can You Outrun a Tornado?

Here’s the thing: you can’t. Even though many tornadoes move around 30 mph and the fastest ever clocked was 73 mph, that doesn’t mean you should hop in your car and try to escape. Tornadoes are unpredictable—they can veer off course, double back, lift off and touch down again without warning. Vehicles offer little protection, and many tornado deaths happen in cars. If you’re under a tornado warning and can’t get to a proper shelter, lying flat in a ditch is safer than staying inside your vehicle.

Final Thoughts: Casual Listening, Serious Lessons

What I appreciated about this Stuff You Should Know episode wasn’t just the facts—it was the tone. Hosts Josh and Chuck are casual, funny, and make the topic accessible without trivializing it. This kind of entry-level learning reminds me why I started this journey in the first place. It’s okay to begin with broad overviews and keep circling back for more depth.

Whether it’s from university textbooks, government resources, or pop culture podcasts, the key is to keep exposing yourself to new angles, busting myths, and letting curiosity do the rest.

So if you’re like me—learning weather one podcast, book, or article at a time—consider this your nudge to keep going. Even surface-level information can spark serious understanding.
