Tornadoes are among the most violent and most powerful natural disasters. They appear as an incredibly fast, rotating column of air that assumes a funnel shape. What makes them dangerous and potentially destructive is the high-speed wind that travels with them. It can seamlessly knock down buildings, toss vehicles into the air, and sweep away trees.

Tornadoes can hit nearly anywhere in the country, but their sting is felt the most in the Midwest and southern states. In fact, some states have experienced so many tornadoes and severe weather that they have earned themselves an unfortunate nickname, Tornado Alley.

How Do Tornadoes Form?

Natural disasters have a unique way in-which they form. Tornadoes form when warm, humid air meets with cold, dry air. The cold air, which is denser, is pushed over the warm air, typically producing thunderstorms. The less-dense warm air, in return, cuts through the cold air, thereby causing an updraft. It’s this updraft that starts to rotate when winds fluctuate in direction or speed.

To put it simply, tornadoes form from really tall thunderstorm clouds named cumulonimbus clouds, and these are the steps:

  • First, a great thunderstorm occurs in a cumulonimbus cloud.
  • That will necessitate a change in the direction and speed of the wind, usually at high altitudes, which causes the updraft air to swirl horizontally.
  • Air rises from the ground, pushing up on the swirling air and consequently tips it over.
  • Then a funnel of swirling air takes up more warm air from below. This funnel stretches and tends towards the ground.
  • It’s this funnel that becomes a tornado when it reaches the ground.

Often times more than one tornado can happen in a single area or time frame. If they happen within the a similar time frame and similar locations. These multi-tornado events are generally called series or outbreaks. These terms can be used interchangeable to talk about the multi-tornado events.

Top 10 States Affected by Tornadoes

Tornadoes and other catastrophes can leave people who weren't prepared stranded and desolate. As a prepper, the goal is to be prepared for any possible life-altering event like an EF5 tornado.

Knowing how likely your area is to be hit by a hurricane will help determine how prepared you should be. Below are the top 10 states regularly affected by tornadoes:

1. Texas

Average Annual Number of Tornadoes: 155

Texas is no stranger to tornadoes. The March 2022‘s outbreak in Austin is the latest of them. According to data from the National Oceanic and Atmospheric Administration (NOAA), Texas reportedly saw over 9,500 tornadoes between 1950 and 2021.

1953 Waco Tornado Outbreak

Between 9 and 11 of May in 1953, a deadly series of tornadoes greeted 10 U.S. states. The strongest one, which was also the deadliest of them, was an F5 tornado that swept through Waco, Texas on May 11. It caused 114 deaths and many more injuries. The 1953 Waco Tornado Outbreak was recorded as the deadliest in Texas history and the eleventh deadliest in the history of the United States.

2. Kansas

Average Annual Number of Tornadoes: 96

Tornadoes are not new to the state of Kansas. Just a few days ago, on April 29, 2022, at least one tornado left about 1,000 structures in ruins between Sedgwick County (one tornado formed here) and Butler County.

Tornado Outbreak of May 4-6, 2007

Some areas in the Central United States saw a major tornado outbreak for three days, from May 4 to 6 in 2007. The deadliest tornado in the outbreak, an EF5 tornado, landed in western Kansas on the evening of May 4. It destroyed at least 95 % of Greensburg, Kiowa County. 13 people died while 60 people suffered different degrees of injuries.

3. Florida

Average Annual Number of Tornadoes: 66

While not necessarily a geographic member of Tornado Alley, Florida sees more tornadoes than most U.S states. Especially the coast between Tampa Bay and Fort Myers. Tornadoes in Florida can occur anytime, however, they mostly occur in the Spring and Summer months.  

1998 Kissimmee Tornado Outbreak

In 1998, between February 21 and 23, a significant tornado outbreak swept through portions of the Southeastern United States. Florida was the primary target. It killed 42 people and injured 259. Otherwise known as the Night of the Tornadoes, the 1998 Kissimmee Tornado Outbreak was the deadliest one in Florida history.

4. Oklahoma

Average Annual Number of Tornadoes: 62

Tornadoes are commonplace in Oklahoma. In fact, it could even be argued that all four seasons in Oklahoma are tornado seasons. Between late March and August, however, sees the most tornadoes. Oklahoma City is among the cities with the highest rates of tornadoes in the United States.

The Woodward Tornado of 1947

On Wednesday, April 9 in 1947, the state of Oklahoma would suffer its deadliest tornado yet. It struck the city of Woodward and would continue into Woods County. In all, 9 people were killed and 42 suffered various injuries.

5. Nebraska

Tornado Outbreak Sequence of March 1913

From March 21 to 23, 1913, a series of tornado outbreaks swept through the northern Great Plains, the Southern United States, and parts of the upper Midwest. The last day was the most devastating as four F4 tornadoes tore through parts of eastern Nebraska and western Iowa. At least, 94 people lost their lives in Omaha that day. To date, the Tornado Outbreak Sequence of March 1913 remains one of the deadliest tornadoes ever to hit Nebraska.
