Tornadoes are one of nature's most awe-inspiring and deadly storms. They pack the highest wind speeds ever measured on Earth, up to 300+ mph. At that speed, a tornado can pick up vehicles, shatter buildings, and launch 2x4s like javelins with enough force to pierce a brick wall! As many states are in the midst of tornado season right now, you might care quite a bit about the likelihood of a tornado hitting your state. No worries, we've got you covered—read on to find out where tornadoes happen most often and learn some basic tornado safety .

This Article: How and Why?

Tornado risk is one of the factors to consider when choosing a new home. How sturdy is the construction and does it have a basement or storm shelter?

From sites such as the NOAA National Severe Storms Laboratory , The Weather Channel, and the National Weather Service, we've compiled a comprehensive list of the states with the most tornadoes. This is information you'll want to take into account when you consider things like travel plans during tornado season, insurance coverage for your property, and fixing up an appropriate storm shelter in your house.

What Causes Tornadoes?

Supercells like this are a specific type of rotating thunderstorm that can give birth to tornadoes.

Meteorologists don't entirely understand how tornadoes form, but in general terms, they are rotating vortexes that form from a specific type of thunderstorm known as a supercell. A convergence of warm and cool air creates a rotating updraft that can become an intensely violent storm up to a mile in diameter. A tornado can last for a few minutes to over an hour. It can settle over one place without moving much or crash over the landscape at up to 90 mph. They are most likely to take place in a windy, relatively flat landscape in the rainy and stormy weather of spring and summer.

What Countries Have the Most Tornadoes?

This is a rare occurrence of a tornado in Lithuania.

By far the United States has more tornadoes than any other country: an average of 1,200 a year. That's about 75% of all the tornadoes in the world. Neighboring Canada has only a hundred or so weak tornadoes each year, given its colder temperatures. A second geographic region with concentrations of tornadoes is the so-called "Tornado Corridor" in South America, including parts of Argentina, Paraguay, Uruguay, and Brazil. Europe as a whole has about 250 tornadoes a year, with the most number per land area concentrated in the UK. Australia suffers about 50 tornadoes a year. The deadliest tornadoes take place in Bangladesh, as they are of similar intensity of those in the United States but occur in conditions of heavy population and inadequate medical care.

What States Have the Most Tornadoes?

Cold and warm air collide over the broad plains of the midwestern United States, creating more tornadoes there than any other region.

Most tornadoes in the United States happen in "Tornado Alley"—a band of states in the center of the country with no clear geographical boundaries, but usually including the Plains states from the Canadian border south through Texas, and from as far west as Colorado to as far east as Ohio. This area has ideal climactic and geographical conditions for the formation of big and frequent tornados.

The Midwest

This tornado-spawning storm occurred in Illinois, considered part of "Tornado Alley."

The Wizard of Oz helped sear Kansas in our minds as tornado country, and rightly so. Only Texas, a vastly larger state, has more tornadoes. Although the Great Plains are one of the most sparsely populated areas of the country, the frequent tornadoes there can flatten crops and destroy agricultural equipment and infrastructure. The costs get passed along to all of us through higher insurance rates and food prices to cover these losses.

• Kansas: 87
• Illinois: 57
• Iowa: 53
• Missouri: 53
• Minnesota: 46
• Nebraska: 45
• North Dakota: 29
• South Dakota: 28
• Indiana: 27
• Wisconsin: 26
• Ohio: 23
• Michigan: 12

The South

Parishioners survey the damage to their church after a tornado in Alabama.

Sensational media references and Hollywood films about "Tornado Alley" can create a sense of complacency about the danger of these storms in other parts of the country. In fact, the American South is equally subject to frequent tornadoes. In part, this is because the region is also a prime target of Atlantic and Caribbean hurricanes, which often spawn numerous tornadoes. The South gets nighttime tornadoes more frequently than other parts of the country, and this makes them more deadly as sleeping people don't always hear alerts and sirens. Alabama has had some especially deadly storms over the years.

• Texas: 124
• Oklahoma: 66
• Alabama: 64
• Mississippi: 63
• Florida: 46
• Louisiana: 45
• Georgia: 40
• Arkansas: 38
• North Carolina: 32
• Tennessee: 31
• Kentucky: 29
• South Carolina: 26
• Virginia: 21
• Maryland: 8
• West Virginia: 2
• Delaware: 1

The Northeast

New York may seem an unlikely place for a tornado, but as this resident of Long Island discovered, they do happen there on occasion.

The Northeast is the area with the fewest tornados, but Pennsylvania and New York, the largest states in the region, have the lion's share. The region occasionally suffers a tornado-spawning hurricane, or the after-effects of one that travels up the coast from the South. Rhode Island is the only state that averages zero tornadoes a year. They have occurred there, but so infrequently that in an average year there is unlikely to be one.

• Pennsylvania: 16
• New York: 9
• C0nnecticut: 2
• Maine: 2
• Massachusetts: 2
• New Jersey: 2
• New Hampshire: 1
• Vermont: 1
• Rhode Island: 0

The West

The Prospect Valley tornado touched down in Colorado in 2018.

In the West, Colorado gets by far the most tornadoes. If your mind immediately goes to the Rocky Mountains when you think of this state, keep in mind that the eastern half of it is a plain just like neighboring Nebraska and Kansas. Tornadoes do happen in the mountains as well, though. In Wyoming, for example, a strong tornado touched down and crossed the Continental Divide in Yellowstone National Park. You might be surprised to see Alaska on the list at all. Though rare, there have been documented cases of tornadoes there, including photos of one touching down on a mountain peak.

• Colorado: 41
• New Mexico: 9
• Wyoming: 9
• California: 8
• Arizona: 5
• Montana: 5
• Idaho: 3
• Washington: 3
• Nevada: 2
• Oregon: 2
• Utah: 2
• Alaska: 1
• Hawaii: 1

Tornado Tips

Falling debris, gas leaks, and exposed power lines are some of the life-threatening hazards to avoid in a tornado-damaged neighborhood.

There's no need to live in terror of tornadoes, but there's no need to be caught completely unprepared, either. Knowledge and preparation can help ease your mind, knowing you have done all you can to get ready for a worst-case scenario that, with any luck, will not actually come to pass. Next are some suggestions from the American Red Cross and others to help keep you, your property, and your family safe during and after a tornado.

Tornado Preparation

It's smart to set aside some emergency supplies not only for a tornado but for any number of other kinds of emergencies.

• Install a free weather app on your phone to alert you of severe weather events.
• Memorize the difference between a tornado watch (a tornado is possible) and a tornado warning (a tornado is near). Maybe this will help you remember: if a police officer is watching you, keep doing what you're doing, but be careful. If the police officer is warning you, immediately do something different, or you're going to be in real trouble.
• Store bottled water, non-perishable food, a backup phone battery, a battery-powered radio, and necessary medications in your shelter.
• Keep essential documents backed up electronically and/or in hard copies in a waterproof container in your shelter.
• Practice tornado drills with your family and pets. Do not search for pets during a tornado, as you may have only seconds to get to safety.

During a Tornado Warning

Tornado warnings have to be taken seriously. You may have only seconds to get to safety.

• Take shelter in a basement or storm shelter. If you don't have one, take refuge in the lowest level of your house in a small windowless room.
• If you are driving, it is not safe to stay in your car. The wind can get under the vehicle and roll it or fling it airborne.
• Get out of the car and run to a sturdy building or lay down in a low-lying area. If there is absolutely no time to abandon the car, then tighten your seat belt, get down as low as possible, and cover your head.
• Never take shelter under a highway overpass. It acts as a wind tunnel that accelerates the speed and force of the wind.

After the Tornado

Falling debris, gas leaks, and exposed power lines are some of the life-threatening hazards to avoid in a tornado-damaged neighborhood.

• Follow all instructions of emergency personnel. Even if your home is not damaged, it may be necessary to evacuate because of the danger of gas leaks or other hazards in nearby homes.
• Once evacuated, do not return to your home until officials have given the all-clear.
• Be alert to the possibility of gas leaks, downed power lines, falling debris, and sharp nails and glass on the ground.
