Lightning may not strike the same place twice, but tornadoes do. Moore, Oklahoma, which was devastated yesterday, was also hit in 1999 and 2003.
This time winds of up to 200 mph flattened whole neighbourhoods. Schools were destroyed, and at least 24 people have been killed. President Obama has declared it a major disaster. Tornadoes, hail and high winds also hit Iowa and Kansas.
The 1999 tornado (pictured) caused devastation for nearly 40 miles, killing 41 people, destroying thousands of homes, and inflicting damage that cost more than $1 billion. In 2003, houses, businesses, two hotels and a church were among the buildings destroyed or damaged.
The most devastating twister in US history was the Great Tri-State Tornado of 1925, which wrought havoc in Missouri, Illinois and Indiana, killing around 700.
