I grew up in what was, and is, called \u201cTornado Alley.\u201d Beginning just about this time of year and lasting until the first part of June, tornado warnings were pretty much a daily occurrence. When I was a kid, it seems like most tornadoes struck somewhere along Tornado Alley, a flat stretch of land from western Texas to North Dakota. This region was a hotspot for tornadoes because the dry polar air from Canada met the warm moist tropical air from the Gulf of Mexico \u2014 for most of the rest of the U.S, tornadoes were a rarity. But for whatever reason, that\u2019s changed today\u2026. just about anyplace can have a tornado.\u00a0<\/p>\n\n\n\n
My mother was the ultimate \u201ccloud watcher,\u201d especially around this time of the year and she almost never saw a cloud that she didn\u2019t think a tornado was going to drop out of. I heard all sorts of her theories about tornadoes and some I still hear today, but most of them are simply not true. <\/p>\n\n\n\n
When we lived in Oklahoma, pretty much all<\/em> the weather moved from the southwest to the northeast. I still hear today that you should go to the southwest corner of your basement during a tornado warning. Tornadoes can move in any direction, so hiding in one corner is no more beneficial than any other. In fact, occupying the area that is closest to the approaching tornado \u2014 whether above the ground or in the basement \u2014 results in the most fatalities. A study conducted in the 1960s showed that the north side of a house is the safest area, both above ground and below. I might mention that where I grew up in Oklahoma, houses didn\u2019t have basements, so during tornadoes, people went the \u201csouthwest corner\u201d of their houses \u2014 or into the bathroom, which was supposedly a safer place because of the plumbing pipes being well anchored in the ground. But most people, like my mother, insisted on having a storm cellar \u2014 a hole dug underground to protect you from tornadoes.<\/p>\n\n\n\n Another (false) precaution that minimizes damage due to a tornado, is opening all the windows in your house \u2014 to equalize the pressure. Engineers agree that a storm with 260-mile-per-hour winds \u2014 classified as an F4, or \u201cdevastating\u201d tornado \u2014 creates a pressure drop of only 10 percent. Houses and building have enough vents and natural openings to easily accommodate that. <\/p>\n\n\n\n One belief is that tornadoes never strike large cities. This is another myth that persists today. The combination of traffic, dense activity, and considerable amounts of concrete and asphalt in large cities creates what is known as a \u201cheat island.\u201d This rising warm air has the potential to disrupt minor tornado activity, but it\u2019s no match for the fury of larger tornadoes. Cities also occupy a much smaller geographic area than rural regions of the country, so the chance that a tornado will strike a city is relatively small. But \u2014 on a single day in 1998, three major tornadoes struck Nashville, Tennessee. St. Louis, Missouri, witnessed ten tornadoes between 1871 and 2007, resulting to more than 370 deaths. An F3 tornado tore through Dallas in 1957. In 1997, tornadoes touched down in Miami and Cincinnati, and another hit Fort Worth, Texas, in 2000.<\/p>\n\n\n\n Other \u201cmyths\u201d about tornadoes I grew up hearing constantly include\u2026Tornadoes are alway clearly visible ahead. No \u2014 tornadoes can be obscured or even invisible due to rain or nearby clouds. The formation of a tornado is so complex that scientists still don\u2019t completely understand it. And the unpredictability of tornadoes makes them difficult \u2014 and dangerous \u2014 to study. A tornado will demolish everything in its path, including measuring equipment. And so, the secrets behind one of nature\u2019s mysteries are yet to be discovered\u2026. Happy Spring!

If you\u2019re in a car, you can out-drive a tornado. No again \u2014 tornadoes can travel well over 60 mph\u2026 and cars can easily be lifted or blown over by the storm.
The best protection from a tornado while in the car is hiding under an overpass. Experts agree that this will put you at more risk. The structure may not be stable and increases your risk of bing hit by flying debris.\u00a0
You only need to worry about tornadoes during \u201ctornado season.\u201d That almost, kind of, seemed to be true when I was growing up, but today tornadoes often happen at any time of the year, not just the spring.\u00a0<\/p>\n\n\n\n
