  • The furious winds of a hurricane, impenetrable blizzards, or the stifling heat of a drought

  • these are horrible manifestations of nature’s wrathalso known as Bad Weather!

  • But not many of them can compare to the fastest winds in the world.

  • Whirling up high, turning fields into wastelands, tearing trees out from the ground, and ruining

  • townsthat’s right: tornados.

  • More Bad Weather.

  • Still, survivalists say that anyone can prepare for a twister!

  • So let’s find out how to survive a tornado!

  • The first and most important thing any experienced weatherman, survivalist or tornado chaser

  • will tell you is you need to know what youre dealing with.

  • Without a clear understanding of what exactly a tornado is, every other tip or piece of

  • advice has a good chance to fall flat and do no good after all.

  • A tornado can emerge even when there’s no storm or rain.

  • It comes without knocking; and its formation is sudden and quick.

  • It might take only a few minutes before a tornado starts to wreak havoc upon everything

  • in its path.

  • Most of the time they appear in the summer when the ground is heated and the upper parts

  • of the atmosphere are influenced by cold winds brought on by thunderstorm supercells.

  • The hot air tends to produce updraftsan ascending stream of warm air.

  • At the same time, thunderstorms bring rain and a descending stream of cold air called

  • a downdraft.

  • As you can imagine, these two rapid airstreams colliding with each other isn’t a great

  • thing for anyone.

  • Warm air can’t flow higher up and cold air can’t go lower.

  • The force of their collision creates a spinning wall cloud right below the level of the parenting

  • storm.

  • With time, both the updraft and the downdraft become stronger and stronger.

  • It eventually produces a vertical column of spinning air that starts to suck debris from

  • the ground like a giant drain.

  • This is when the funnel of a tornado appears from the spinning wall cloud.

  • It makes its way down from the cloud to the ground as if the storm itself tries to suck

  • up the earth with a long weird snout.

  • And it won’t shy away from taking everything for a ride.

  • The force of the thing is immense.

  • Just try to imagine: a tornado can be up to 2 miles in diameter.

  • The wind speed sometimes surpasses 300 mph, and the speed of the funnel itself traversing

  • the land is somewhere between 25 to 40 mph; but in some cases, it can reach 70 mph.

  • You wouldn’t want to race with something like that, and it’s certainly not a welcome

  • guest in your back yard.

  • But what can you do to avoid meeting a twister?

  • The main way to assure your safety is to be aware of your surroundings, and plan in case

  • a tornado comes your way.

  • Most tornadoes happen in a warmer time of year, and their favorite place on Earth must

  • be the US.

  • In fact, there’s even a term: ‘Tornado Alley’, which includes most of the Southeastern

  • and Midwestern parts of the country.

  • But don’t think that youre safe outside of these regions!

  • Believe it or not, tornadoes have appeared in the middle of winter, and in the least

  • obvious places.

  • Meteorologists are still working hard on gaining more knowledge about tornadoes and the origins

  • of their formation.

  • Considering a warning is your best chance at survival, it’s a good thing they figured

  • out how to predict them for the most part.

  • And more than that, you too could become a tornado spotter.

  • These are specially trained people that can detect the very first signs of a storm that

  • can produce a tornado.

  • There are more than 230,000 of these vigilant storm-watchers across the US.

  • Their main task is to see if the storm is a supercell producing a wall cloud.

  • Theyre not really hard to see: it looks like a giant bulge in the cloud base that

  • starts to spin as an updraft from the ground strikes it.

  • The moment they see a wall cloud starting to split into bands calledbeaver tales’,

  • they know that theyre looking at the birth of a tornado.

  • But how do they know which way to look?

  • This is where technology comes into play.

  • Meteorologists use weather radar, which is based on the Pulse-Doppler method.

  • Pulse-Doppler radars can detect raindrops and effectively calculate the distance to

  • them and their velocity.

  • Based on that information, meteorologists can form a full picture of changes in the

  • weather.

  • The same radars can detect rotation in storm clouds from more than 160 miles away.

  • When observers confirm the first signs of upcoming tornadoes, the emergency warning

  • will immediately go off.

  • You would need to sit in a bunker to miss this one, because itll be literally everywhere.

  • Speaking of bunkers, you would probably be glad to have one nearby, or at your own disposal,

  • if youre about to weather something like an F-3 category tornado.

  • And there are 6 of these categories, so you can imagine what youre up against with

  • anything stronger than an F-3.

  • If you still can’t, here’s a quick rundown for you.

  • An F-0 tornado is more like a landspoutit won’t cause any significant damage.

  • To be safe you would need to just trim the tree branches closest to your windows so they

  • won’t break them.

  • Otherwise, your home is your castle.

  • An F-1 tornado, with wind speeds up to 110 mph, is more of a concern.

  • Hope you don’t live in a mobile home; and if you dofind another place to hide.

  • Tornadoes this strong can easily push a mobile home off its foundation.

  • An F-2 tornado can tear small trees out from the ground.

  • Any mobile home would be destroyed by it.

  • Even the roofs of well-constructed houses will partially crumble under the furious wind,

  • blowing at 160mph.

  • An F-3 tornado is where the real trouble begins.

  • The wind speed can get up to 205 mph.

  • All the upper parts of houses are in danger, and any debris caught by the wind become lethal

  • weapons.

  • These tornadoes can lift cars and break brick walls.

  • F-4 and F-5 tornadoes are the rarest, but also the most dangerous.

  • If you ever hear that something like that is coming your wayit’s best to find

  • a bunker, safe room, or an underground shelter nearby.

  • These monstrosities can make buildings literally come off the ground, and cars fly in the air

  • for 300 ft.

  • Fortunately, there are a lot of shelters that are specifically built to protect anyone from

  • tornadoes and storms; and you don’t really need to have a personal one for yourself.

  • But what would be nice to have is an emergency kit, just in case.

  • The most useful things for a survival kit would be rain gear, flares, a radio, a first-aid

  • kit, an air horn, a flashlight with some extra batteries, a mechanical can opener, at least

  • 3 gallons of water per person, a stock of ready to eat meals, and some walkie-talkies.

  • Make a stash with all of that somewhere in your house, and youll always be prepared.

  • The worst-case scenario is if a tornado catches you off guard.

  • Imagine youre driving a car and suddenly a twister appears in front of you from a huge

  • raincloud.

  • What would you do then?

  • The first thing that comes to mind is to just turn around and drive away from it as fast

  • as possible, but, that’s a poor choice of actions.

  • The best way to avoid a tornado in a car is to figure out the direction it’s going and

  • take a course about 90 degrees from this direction.

  • But remember, if it is close to youdon’t think that your car will protect you.

  • It’s not only the wind that’s scary about a tornado.

  • More so are the debris that it spins around; it could severely damage your car in a matter

  • of seconds.

  • It’s best to leave the car and stay as far away from it as you can.

  • In this worst-case scenario, your best option is to find a ditch, lay low, and cover your

  • head with any possible means.

  • Still, any nearby building’s basement would be a better hiding place, except the big ones.

  • Shopping malls or cinemas could be extremely dangerous if you want to hide from tornadoes.

  • The myth that larger structures are safer is just a myth.

  • And that’s not the only myth about twisters.

  • Telling them from the truth may be crucial for surviving a disaster.

  • One suggests that it’s better to open windows during a tornado, and that’s as false as

  • it gets.

  • Wind going through open windows could lift whole floors or a roof with ease!

  • More than thatit’s important to leave windows closed and to stay away from them

  • until the whirlwind is no more.

  • Another important misconception is that smaller tornados are weaker and less dangerous.

  • That’s also not true.

  • A lot of F-4 tornadoes were no wider than just 300 ft in diameter, but they did a ton

  • of damage.

  • Twisters aren’t stable, they change their shapes constantly.

  • So don’t just trust your eyesall tornadoes are equally dangerous.

  • No matter how small or slow-looking a twister istry to not underestimate it, and always

  • use every method of avoiding trouble.

  • How about you?

  • Have you ever seen a real tornado?

  • Let me know down in the comments!
